MIL-STD-871 reactivated

MIL-STD-871, “Electro-Chemical Stripping of Inorganic Finishes,” has been reactivated and is now valid for both new design and replacement purposes.  The new Revision C is dated 6/30/2015 and is 20 pages in length.  A summary of the changes to this new edition can be found in the introductory material for the standard.  It’s available from Document Center Inc. in paper format, for pdf download, and as part of our Standards Online multi-user subscription service.

The U.S. Air Force is the caretaker for the MIL-STD-871, but the document is available to all the forces for use in purchase orders and contracts.  As a standard, it is an overview document on the process and materials used for stripping inorganic finishes.  Such finishes can include anodic coatings, chromate filming, nitriding, passive films and so on.  It also covers heat treating techniques that can be used after stripping for hydrogen embrittlement relief of the steel substrate.

Why will you want to use the MIL-STD-871?  First, in recent years there has been a concerted effort on the part of all of U.S. government procurement to reduce or eliminate the use of toxic and hazardous materials.  Since these types of stripping processes have relied heavily on the use of such chemicals in the past, this standard does provide you with a variety of chemical compounds that should be used moving forward.  Many of the stripping compounds chemical compositions have been modified.

Secondly, if you do work for the Air Force, particularly component repair, this is the document that is designed specifically for the task of repair and remanufacturing.  It covers the processes and the stripping solutions that are appropriate for this application.

IEC 62304 and it’s new amendment

IEC 62304, “Medical device software – Software life cycle processes,” has just been amended.  This new amendment 1 can be purchased from Document Center Inc. in two ways — As part of a consolidated Edition 1.1 or as a stand-alone Amendment 1.  Let’s talk about the pros and cons of these two formats and the changes that the new amendment makes to this important medical device standard.

First, if you purchase the amendment by itself, the cost is far less ($ 285.00) than getting the consolidated edition ($728.00).  You’ll have the changes clearly identified as they will be the only content of the document.  This makes your gap analysis safer, as you can be sure that you’ve addressed all modifications that have been made to the document.  However, with the extensive changes that have been made to the standard, it will be difficult to compile the data into one usable document once your analysis is complete.

The consolidated Edition 1.1 includes those same changes, with the document divided into two parts.  The first half of the publication is a Redline Edition, with changes identified by the use of a line in the margin and red typeface for all updates.   That’s followed by a Final Edition with the new text in full.  This will be easier to use once the gap analysis is complete, that’s for sure.

Now for the significance of the revisions.  Amendment 1 for IEC 62304 was developed to  address the issue of legacy software, that is medical device software designed prior to 2006 when the Edition 1.0 was released.  Why?  Because manufacturers need help to prove compliance with various European Directives.  Wouldn’t you know it — that means clarification of requirements and updating the classification to include a risk-based approach.

It’s taken a joint working group of subcommittee IEC TC62A, IEC TC62, ISO TC210, and ISO/IEC JTC 1/SC7 to write this update.  You’ll find there are significant and extensive changes to the document.  The amendment 1 alone consists of 46 pages of corrections.  Since the consolidated final edition is a total of 82 pages, you can see what I mean.  Changes occur in almost every section of the standard.  Some are simple corrections like those to a referenced document number to reflect the correct year of the current edition.  Others are major modifications, as to the update for Clause 4.3 on software safety classification.

How much time do you have to make the transition from the Edition 1.0 to the Edition 1.1 or Edition 1.0 with the Amendment 1?  The committee states in the introductory material that you have 3 years to make the required changes to your affected products.

What does the future hold for IEC 62304?  The committee is working on an Edition 2.0 right now to further refine the document to meet the challenge of the changes in the understanding of risk-management that is affecting many European medical device standards right now.

IEC reminds you to be sure you’ve purchased your copy from an authorized dealer and Document Center Inc. is the one you’ll want to use.  We offer the IEC 62304 in both paper and pdf format, and you can get multi-user access by including it in your Standards Online subscription service as well.  Order online at our webstore,  Or go direct to the link for either the IEC 62304 order page or the IEC 62304 Amendment 1 order page.  And if you need a personal touch, contact our staff by phone (650-591-7600), fax (650-591-7617) or email (

Elsmar Cove is closed!

Elsmar Cove, a discussion forum for both professionals and novices in the business of quality assurance and industry standards, is closed.  It is clear that the site is already missed by thousands of users.  And folks who’ve come to rely on the “people helping people” Elsmar ethic are scrambling for venues to replace the information-sharing service the site provided.

Since both Document Center and Elsmar Cove have (had) a mission to help people understand standards and use them effectively, founder Marc Timothy Smith and I had a phone conversation on Monday to discuss Elsmar and it’s closing.

What happened to Elsmar Cove?  As noted on the website’s homepage (and only page now), it’s has been closed as part of a settlement that stemmed from a civil lawsuit filed in Florida. Mr. Smith, who founded the site in the mid 1990’s, is not allowed to reveal any details of the settlement that resulted in the closure of the Elsmar Cove.

What made Elsmar Cove special?  First and foremost, the site was a free resource for anyone with a question about quality assurance, national and international standards, regulations, or compliance.  Elsmar Cove was originally started as a informational website and evolved over the years into a discussion forum specifically geared to the questions folks have when dealing with many specialized niches.  It gave you a place to ask if anyone has faced a particular quality assurance related problem and find out what solutions have proved to be effective.

Elsmar Cove was a moderated site, with perhaps 10 moderators active at any given time but a stable of 25 to 30 in total.  Why moderated?  Like it’s founder, Elsmar was interested in providing an environment for sharing rather than self-promotion.  So folks with strong quality backgrounds monitored the forum to make sure that interchanges were on topic and focused on the mantra of “People helping People.”

Who is Marc Timothy Smith?  Mr. Smith is an “old quality hand” with extensive experience stemming from work with military quality systems back in the 1980’s.  His background in biology and chemistry from his college years made him particular strong in processes, using flow charts for both business analysis and quality control.   Since he’s from the Ohio area, his defense gig soon morphed into consulting work in the automotive and aerospace industries and beyond.  Stints included work for such companies as Harley Davidson, Motorola, Ford, Borg-Warner and Boeing.

As a side-line, Mr. Smith started a quality assurance information website in January, 1996.  Over time, this became the discussion forum we’ve come to know and love.  With the gradual expansion of the forum, Marc found himself concentrating on the service and it’s software backbone by 2003/2004.  Only after early 2004 did Marc turn to Adsense and other advertising for the financial support that’s needed to operate such an extensive site.

Will Elsmar Cove be back?  No, the Elsmar Cove you’ve known will not be returning.  However you will find a number of niche forums cropping up as various moderators create venues based on their areas of expertise.  For example, those of you in the medical device field should now check out

What’s next for Marc Smith?  You can bet that Mr. Smith is looking for the next opportunity to make a contribution to the quality assurance and standards community.  His extensive consulting background is only one of the assets he possesses.  From his unique perspective watching and monitoring the landscape of the quality field, he offers a wealth of experience in understanding the compliance challenges many companies and industries face.

Never much of a self-promoter, he’s always relied on recommendations to generate business for himself.  But he still has an on-going interest in the quality community, in the requirements for compliance that face many businesses, and in participating in helping others achieve success.  Of course, his CV is lengthy displaying a familiarity with the quality concerns of a broad range of industries.  And his experience with Elsmar has only further expanded his grasp of the continuing concerns around which most quality issues revolve.  Check him out at or reach out to him at

As our conversation wrapped up, I ask Marc what legacy he hoped Elsmar Cove would have.  Of course, he replied “People helping people.”  There’s no question that he achieved that goal.  I’m looking forward to seeing what door opens for him in the next phase of his fascinating career!

As for me, there’s still a lot of questions about what happened.  It looks like I’m going to have to do some sleuthing on my own to get any answers, if they’re out there at all.  If I find them, you’ll be the first to know!

New ANSI Z308.1 2015 Edition – Workplace First Aid Kits

ANSI Z308.1, “American National Standard – Minimum Requirements for Workplace First Aid Kits and Supplies,” has just been revised.  The new 2015 Edition is available from Document Center Inc. now.  The new edition corrects a measurement error in the 2014 Edition which was released at the beginning of this year.  It also has a number of other new updates that I’ll review below.

Are there new classes of first aid kits in this update?  Yes, there are two classes of first aid kits that have been introduced in the ANSI Z308.1 2015 Edition.  These classes are based on based on the assortment and quantity of first aid supplies.  Class A kits are for the most common workplace injuries, like minor cuts, abrasions and sprains.  This means Class B kits contain more variety and quantity of supplies for injuries that might occur in more complex or high-risk environments.

Are there other classifications for workplace first aid kits?  Yes, there are 4 types of kits: Type I is usually mounted on a wall, Type II is portable for indoor use, Type III is for both indoor and outdoor use, is portable but can also be mounted in a fixed position, and Type IV is again for outdoor use but has a more rigorous list of requirements regarding moisture, etc.

What else is covered in the ANSI Z308.1?  The standard not only tells you what type of kit to use for specific situations, but also the supplies that need to be included in each type of kit.  Additionally, it provides you with the specific marking and labeling requirements each must have.

Who wrote this new standard?  ANSI Z308.1 is developed by ISEA’s Industrial First Aid Group using the accepted consensus principles and practices required by ANSI.  This means that the standard is able to be adopted as an American National Standard.  Additionally, OSHA often refers employers to this standard as a best practices solution for the requirements of  Paragraph (b) of 29 CFR 1910.151 if a company does not have an infirmary.

What is the correction in this new edition of the Z308.1?  ISEA says, “The 2015 revision corrects a minor measurement conversion error in the 2014 edition (previously released January 2015), with respect to the U.S. measurement for minimum application for antibiotic and antiseptic supplies.”

Where can I get a copy of the ANSI Z308.1?  You’ll need to get a copy from an authorized distributor of the standard since it is a copyright publication.  Choose Document Center Inc.  You can order online at our webstore,  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  And here’s a link to the order page for ANSI Z308.1 directly.  Remember, we’ve been selling standards since 1982.  Make us your Standards Experts!

Fireworks Standards for your 4th of July!

Have a safe and happy 4th of July!  That’s our message for this weekend and it is made possible by those Standards Professionals who write fireworks standards! Here in the U.S., you’ll find fireworks standards provided by NFPA (the National Fire Protection Association) and AFSL (the American Fireworks Standards Laboratory).  In Europe, this topic is covered by the CEN Technical Committee 212 and ISO Technical Committee 264.

AFSL has issued the following standards:

  • AFSL 101 – Standard for Combination Items
  • AFSL 102 – Standard for Comets, Mines, and Shells
  • AFSL 103 – Standard for Firecrackers
  • AFSL 104 – Standard for Fountains
  • AFSL 105 – Standard for Ground Spinners and Chasers
  • AFSL 106 – Standard for Specialty Items
  • AFSL 107 – Standard for Party, Trick, and Toy Smoke Devices
  • AFSL 108 – Standard for Reloadable Tube Aerial Shells
  • AFSL 109 – Standard for Roman Candles
  • AFSL 110 – Standard for Sky Rockets, Missiles, and Helicopters
  • AFSL 111 – Standard for Hand-Held Sparkling Devices
  • AFSL 112 – Standard for Wheels
  • AFSL 113 – Standard for Girandolas
  • AFSL 114 – Standard for Crackling Strips

You’ll find these standards at the AFSL website.  The publication includes all the standards plus a series of Appendices which cover general topics like the chemical that can and cannot be used, transportation regulations and so on.  I admit — Every kind of fireworks goody I can think of is certainly covered here!

NFPA on the other hand provides the following 3 standards:

  • NFPA 1123, Code for Fireworks Display
  • NFPA 1124, Code for the Manufacture, Transportation, Storage, and Retail Sales of Fireworks and Pyrotechnic Articles
  • NFPA PYR 1129, Standard Method of Fire Test for Covered Fuse on Consumer Fireworks

In Europe, there’s quite a number of standards on this topic.  It’s easiest just to peruse the list using the ICS classification code for fireworks.  Here is the link to our Document Center List of Standards on Explosives, Pyrotechnics and Fireworks.  You’ll find it’s quite lengthy!

So there you have it.  Lots of fireworks standards available — All developed with one thing in mind:  Keeping us safe when we get the thrill of seeing those wonderful fireworks displays like those that will be happening this 4th of July!  Here at Document Center Inc., we hope you and yours have a great holiday and a safe one!

New EN ISO 11137-2 2015 Edition

EN ISO 11137-2, “Sterilization of health care products. Radiation. Establishing the sterilization dose,” has just been updated.  The new 2015 Edition is being released in the various national adoptions from the members of the EU now.   This update leaves the adopted ISO 11137-2 2013 Edition untouched — the changes are all to the Annex material.

What is the EN ISO 11137-2?  It is the European adoption of ISO 11137-2.  Here’s how this is phrased in the endorsement notice: “The text of ISO 11137-2:2013 has been approved by CEN as EN ISO 11137-2:2015 without any modification.”  Additionally, the EN ISO 1137-2 is on the harmonized list of standards for the 3 medical device directives: 90/385/eec, 93/42/eec, and 98/79/ec.  So it is an important part of the documentation requirements for many medical device manufacturers who sell products in Europe.

What are the changes in the 2015 Edition of EN ISO 11137-2?  First, the introductory material includes clarification of what documents should be used as referenced standards.  Then, since the document continues to adopt the ISO 11137-2 without any modifications, the balance of the changes are contained in the Annexes (ZA, ZB, and ZC — one for each of the directives it applies to).

If you are already using any of the ISO adoptions on these 3 directives’ harmonized lists, you know about the problems that risk assessment is causing at the present moment.  So it will be no surprise that this update seeks to clarify the situation as regards to the ISO 11137-2 material.  There is the addition of 4 notes at the beginning of each of the 3 Annexes.  Note 1 provides you with a straight-forward statement of the expectation of the reduction of risk.  Note 2 then expands on this with the requirements for a manufacturer’s policy regarding acceptable risk.  Note 3 confirms that the “normative references” (reference documents) in the Annex are the European adoptions as laid out in the forward and noted above.  Note 4 reminds you that any Essential Requirement of your directive is not met if it does not appear in the appropriate directive’s Annex.

The last change to each Annex is actually an update for the table that is contained in each.  The third column for each table has been expanded.  This means, in part, that only sterilization using ionized radiation is covered by the publication.  And it is now emphasized that other aspects of manufacture not relating to sterilization are not covered by this document.  The previous other notes continue to be in force.

When will it be mandatory to meet this new edition?  First, when the update is formally accepted and added to the harmonized lists, there will be the cessation date for the 2013 Edition included on the list itself.  And even though this has not yet taken place, it is expected to be processed without issue.  Secondly, the member nations of Europe have until December 2015 to adopt this document and withdraw any conflicting or duplicating standards.  So we’d make that our preliminary migration date until the new harmonized list comes out.

How do I comply with these changes to the Annexes?  Remember, standards give you the presumption of conformity to specific Essential Requirements (ER’s) of specific directives.  But there may be other ER’s that the directives do not meet.  This means that you’ll have to address these types of issues in your technical file.  The new material in the Annexes seems to indicate that your company policy with regards to risk management will be at scrutiny.  And you may also need to prove compliance in this regards for the covered device as well.

How can I get a copy of the new EN ISO 11137-2 2015 Edition?  All national adoptions are covered by copyright, so you’ll want to purchase your copy from an authorized distributor like Document Center Inc.  Order on our webstore,  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (

What national adoption should I purchase?  Right now, the BS EN ISO 11137-2 2015 Edition is available in paper format only.  The SS EN ISO 11137-2 (in English) is expected to be released any day now and will be available in paper format, for pdf download and as part of our Standards Online multi-user subscription service.  The English language edition of the DIN EN ISO 11137-2 should also be available soon and can be purchased in paper format or for pdf download as well.  At that point, the only other difference between the 3 editions will be the price.

It is mandated that you use the EN editions of ISO adoptions when you’re meeting the requirements for directives with harmonized lists.  But if you’re like our Document Center customers, this still leaves you with many questions.  We’re here to help you navigate these waters, so make us your Standards Experts!

New ISO 17842 Series – Amusement Ride Safety

There’s a new ISO 17842 series out now, covering the full range of requirements for developing, manufacturing, inspecting and operating amusement rides safely.  It’s a 3-part series designed to cover rides like swings, boats, Ferris wheels, roller coasters, chutes, grandstands, stages, sides shows and the like.  With summer here, many of us will be taking our kids to theme parks and the like.  Just the time when we want to know that the rides they love so much are safe!

Let’s review each of the new documents one at a time:

ISO 17842-1, 1st Edition, “Safety of amusement rides and amusement devices – Part 1: Design and manufacture”

This new standard refers to amusement rides, etc., as amusement devices.  So you can also think of it for rides that carry passengers.  The Part 1 is lengthy (165 pages in all).  After the usual scope, referenced documents, and definitions sections, it moves right into the requirements for design analysis and examination.  This covers design documents including design risk assessment, selecting materials, design loads, structural analysis, stability, anchorages, strength and construction.  Section 5 is an in-dept review of the requirements for both the design and the manufacture of these types of rides and structures.  Then 9 Annexes provide you with information on fatigue analysis, electrical equipment and control systems, passenger containment, device logs, hazard lists, guest behaviors, accessibility, and what’s called the safety envelope for passengers.  A 23-item bibliography completes the standard.

FYI: A couple of things to note.  The document is intended to be applicable for rides manufactured after the date of publication.  And existing national rules on such things as worker safety are not addressed in the document.

ISO 17842-2, 1st Edition, “Safety of amusement rides and amusement devices – Part 2: Operation and use”

This part of the ISO 17842 is concerned with such things as the installation, assembly and dis-assembly, operation, dismantling, maintaining, repairing, modifying and inspecting amusement rides and other similar devices.  It’s intended to be used by controllers, operators, attendants and inspection bodies or by those who train them.   Here’s you’ll review the basics like the need to provide staff with manuals, device logs, and other operational documentation.   There’s a complete run-down of what you’ll need to do to select and train staff who will be working with these types of equipment.

Also covered in Part 2 are the basic requirements for those who are installing the various rides covered by this standard.  This includes where to place the ride, how to assemble the ride on site, and the safety requirements needed during this phase of the operation.  Further, there is coverage of what’s necessary in order to maintain the equipment once it’s been installed including trial operations and other checks.

You’ll also be getting information on working with the public and other operational aspects beyond the issues surrounding the actual equipment itself.  And the duties of the actual operator and attendants are also reviewed.  Special case situations are also included, like annual maintenance reviews and fire safety and training.  Annex A is a table with information on the training, qualification and experience expected of staff who handle various roles.  An 8-item bibliography completes the standard.

ISO 17842-3, 1st Edition, “Safety of amusement rides and amusement devices – Part 3: Requirements for inspection during design, manufacture, operation and use”

This is the shortest of the three parts (12 pages).  It is a requirements standard, with specific procedures and tests for both the initial approval stage and for in-service inspection.  It defines the specific aspects of both installation and operation that need to be confirmed.  This includes the expected schedule and reporting.

When I think of the benefits of standardization, health and safety are always at the top of my list.  In many ways, safety for leisure activities is right up there.  We want to be assured that when we are having fun, we are safe and secure and will be protected from tragedy.  So I’m always appreciative when standards committees develop documents like the ISO 17842 series.

If this is your field, you’ll need copies of these ISO standards.  Since they’re copyright documents, you’ll want to be sure to use an authorized distributor like Document Center Inc.  Head to our webstore at and order your copies in paper format or for pdf download.  Here’s direct links to order pages for ISO 17842-1, for ISO 17842-2, and for ISO 17842-3.

New Edition for EN 55024

EN 55024, “Information technology equipment – Immunity characteristics – Limits and methods of measurement,” has just been updated.  The new 2010 Edition with Amendment A1 is now available from Document Center Inc.  This is the European adoption of the CISPR 24 (same title, currently Edition 2.1 — the 2nd Edition with Amendment 1 interfiled).  It is a harmonized standard for both the 1999/5/EC (Radio and telecommunications terminal equipment) and  and the 2004/108/EC (Electromagnetic compatibility).

At the present time, the EN 55024 2010 Edition with Amendment A1 has not finished the process to add the new edition to either of the Harmonized Lists for these two directives.  So you’ll have some time to review the new update and determine if it will impact your products.

What is the EN 55024 about?  The standard is used for information technology equipment.  It covers continuous and transient, conducted and radiated disturbances, including electrostatic discharges (ESD).  This includes disturbances within the frequency range from 0 Hz to 400GHz.  Requirements and immunity tests are given so that the equipment will perform correctly in a given environment.

What changes does the Amendment 1 make?  The changes in the Amendment 1 for EN 55024 are the same as the changes in Amendment 1 for CISPR 24 Edition 2.0.  These changes were made to:

  • Clauses 4.2.1 and,
  • Tables 3 and A.1,
  • Annex A — Sections A.2.1, A.2.6,
  • Annex A — Figures A.6 and A.7,
  • Annex H — Section H.2, and
  • Annex H — Table H.2.

Why isn’t this new edition of EN 55024 on the Harmonized Lists yet?  Protocol for the official adoption of harmonized EN standards by the European Union itself requires an administrative review and then publication in the Official Journal prior to inclusion on the Harmonized Lists.  CENELEC expects the amended 2010 Edition to make it through this process by late August of this year.

What Edition of the EN 55024 should I be using right now?  Since the amended edition is not officially adopted, both the 2010 Edition and the 2010 Edition with Amendment 1 are current.  However, it is only a matter of time before the new update makes it through the process.  When it is added to the Harmonized lists, you’ll see the migration date in the second from the right column.  This “cessation of presumption of conformity of the superseded document” is the date you’ll need to stop selling any product that does not meet this new Edition’s requirements.

How do I get a copy of the EN 55024?  It’s a copyright document and is only distributed as nation-specific editions like BS EN 55024 and SS EN 55024.  For now, only the BS EN 55024 has been published.  We expect the Amendment 1 to be available separately as part of the SS EN 55024 edition shortly.

Document Center Inc. provides the BS EN 55024 in paper format only.  You can order online at our webstore  Or use this link to go directly to the order page for BS EN 55024.  The SS EN 55024 is available in paper format, for pdf download and as part of our Standards Online multiuser subscription service.  Here is the link to order this SS EN 55024 directly.  The DIN EN 55024 Edition is available in German only, but also in paper format or for pdf download  Here is the link for DIN EN 55024.

ISO 15519-2 – Process Industry Diagrams

ISO 15519-2, “Specifications for diagrams for process industry – Part 2: Measurement and control,” has just been released.  This new standard complements ISO 15519-1 on general rules for these diagrams.  It covers how to prepare different types of diagrams including the use of graphical symbols, letter codes and reference designations.

What kinds of industries should use ISO 15519-2?  This standard has been written for all types of process industry fields.  Some examples of this would be the chemical, petrochemical, power, pharmaceutical, food, pulp and paper industries.

What kinds of diagrams are included in this ISO standard?  You’ll find information on the representation of measurement, actuation and control for process diagrams that include process flow diagrams (PFD), process and instrument diagrams (PID), process control diagrams (PCD) and typical diagrams (TYD).

Does this standard apply to the software that I use to generate process diagrams?  Indeed it does.  The ISO 15519-2 covers both the principles of process diagramming as well as the symbols used and their meanings.  It also reviews the interrelationship between ISO diagrams and IEC diagrams, since process diagrams contain elements of both schema.  So it can be used to understand the criteria by which a rules based system using a defined set of symbols should be implemented.

How is the ISO 15519-2 organized?  It starts with the usual scope, referenced documents and definitions sections.  Next it covers documentation and process control principles and how to exchange process control information.  Section 6 is centered on representation in general.  Then Section 7 specifically reviews representation in diagrams.  In this section, there’s an introduction and then each of the 4 types of diagrams I mentioned above are discussed.  The standard is completed by 5 Informative Annexes and a 14-item Bibliography.  Topics covered in the Annexes include a list of graphical symbols, examples of how to represent meanurement, control, and actuation tasks, diagram examples, the information exchange between process and control equipment, and the relationship between terms for closed loop control, measurement, actuation and so on.

By the way, the standard contains a note from the committee that it plans to withdraw all parts of the ISO 3511 series.  FYI:  The graphical symbols have already been moved over to the ISO 14617 series of standards.  Diagram rules are of course now in this ISO 15519 series.  Letter codes for process variables and control functions are also moving, this time from the ISO 14617 series to this ISO 15519 series.

To get any ISO standard, you’ll need to make your purchase from an authorized distributor like Document Center Inc.  Since this information is copyright, it is inappropriate to have a friend send you over a copy or to get the very inexpensive copies that pop up on illegal sites.  Order with confidence at the Document Center webstore at  Here’s a link for purchasing the ISO 15519-2 directly.

New ASTM E2104 2015 Edition – Radiographic Examination

ASTM E2104, “Standard Practice for Radiographic Examination of Advanced Aero and Turbine Materials and Components,” has just been released.  This ASTM standard provides the minimum requirements for radiographic examination of parts and materials for such applications as turbine engines and flight structures.  The new 2015 Edition cancels and replaces the previous 2009 Edition which is now obsolete.  The document was originally released in 2001.

What is radiographic examination?  It’s the use of x-rays to inspect material, for example to check welds for discontinuities.  It’s a non-destructive test which means that it does not affect the material being inspected.  It can be expensive and does need to be done by properly trained personnel as it involves the use of radiation.

What’s covered in the ASTM E2104?  The standard has the usual scope, referenced documents and definitions sections.  Clause 4 covers significance and use — when it’s to be used and why.  Clause 5 is titled “Basis of Application.”  This covers such topics as personnel qualification, timing of the examination, reporting and so on.  Clause 6 is the body of the publication, general practice.  Here you’ll get the requirements for facilities, safety, equipment and so on.  Clause 7 follows up with the detailed requirements for the testing itself.  Quality concerns are covered in Clause 8, with Clause 9 providing notes primarily for government contract work.  Clause 10 with keywords closes the requirements section.  There is an Annex in this document — it covers the military configuration for IQI (Image Quality Indicator) design.

What’s new in the ASTM A2104 2015 Edition?  This new edition includes references to two additional ASTM standards.  These new standards are referenced in the body of the document, providing users with mandatory changes.
