ISO 9022 Parts 12, 14 and 17 updated

April 6th, 2015

ISO 9022 Parts 12, 14 and 17 have just been updated.  There’s three new Parts: ISO 9022-12 2nd Edition, “Optics and photonics – Environmental test methods – Part 12: Contamination,” ISO 9022-14 2nd Edition, “Optics and photonics – Environmental test methods – Part 14: Dew, hoarfrost, ice,” and ISO 9022-17 2nd Edition, “Optics and photonics – Environmental test methods – Part 17: Combined contamination, solar radiation.”  They are available now from Document Center Inc.  You may purchase authorized copies in paper format, for pdf download or as part of our multi-user Standards Online subscription service.  The ISO 9022 series provides environmental tests used for optical and photonic instruments, equipment whose function is mainly based on optical phenomena.

The ISO 9022-12 2015 is a minor revision of the 1st Edition from 1994.  However, it does cancel and replace the earlier edition, so if you’re using the document you will need a copy of the update.  It relates specifically to tests for the ability of the instrument to resist contact with corrosive chemical substances (the contamination referred to in the title).  Because these tests involve taking samples of material or surface coatings and exposing them to these test agents, most of the time you will not be testing complete instruments.  The tests will thus help you to investigate the resistance of an optical instrument’s surfaces, coatings, and synthetic materials to short exposures.  This is useful during the design phase when you are selecting the materials and components, rather than as part of production control.  There is no guidance from the committee on exactly where the changes have occurred.

ISO 9022-14, on the other hand, does have a redline edition available for the new 2nd Edition.  Again, the committee alerts you to the fact that this is a minor revision.  However, because you have a comparison document available you can see what modifications to this edition have been made.  Here we can find that changes have been made in the following sections of the standard:

  • The foreword
  • The introduction
  • Clause 1, Scope
  • Clause 2, Normative references (referenced documents)
  • Clause 4, Conditioning
  • Subclause 5.1, General (FYI Clause 5 deals with the procedure)
  • Subclause 5.3, Test sequence
  • Clause 6, Environmental test code
  • Annex A, Explanatory notes

For the ISO 9022-17 2nd Edition, this too is labelled a minor revision, replacing the 1st Edition which is now obsolete.   In this case, the tests are for evaluating the effect of corrosive substances (hand sweat, fuels, cosmetic substances, and so on) on test samples when exposed to solar radiation.

FYI:  The ISO 9022 series has been undergoing a number of changes lately.  Here’s the complete list of current editions for the parts that remain in force:

  • ISO 9022-1, 2nd Edition, Optics and photonics – Environmental test methods – Part 1: Definitions, extent of testing
  • ISO 9022-2, 3rd Edition, Optics and photonics – Environmental test methods – Part 2: Cold, heat and humidity
  • ISO 9022-3, 3rd Edition, Optics and photonics – Environmental test methods – Part 3: Mechanical stress
  • ISO 9022-4, 3rd Edition, Optics and photonics – Environmental test methods – Part 4: Salt mist
  • ISO 9022-6, 2nd Edition, Optics and photonics – Environmental test methods – Part 6: Dust
  • ISO 9022-7, 3rd Edition, Optics and photonics – Environmental test methods – Part 7: Resistance to drip or rain
  • ISO 9022-8, 2nd Edition, Optics and photonics – Environmental test methods – Part 8: High internal pressure, low internal pressure, immersion
  • ISO 9022-9, 1st Edition, Optics and optical instruments — Environmental test methods — Part 9: Solar radiation (a new edition is in the works…)
  • ISO 9022-11, 1st Edition, Optics and optical instruments — Environmental test methods — Part 11: Mould growth (a new edition is planned)
  • ISO 9022-12, 2nd Edition, Optics and photonics – Environmental test methods – Part 12: Contamination
  • ISO 9022-14, 2nd Edition, Optics and photonics – Environmental test methods – Part 14: Dew, hoarfrost, ice
  • ISO 9022-17, 2nd Edition, Optics and photonics – Environmental test methods – Part 17: Combined contamination, solar radiation
  • ISO 9022-20, 2nd Edition, Optics and photonics – Environmental test methods – Part 20: Humid atmosphere containing sulfur dioxide or hydrogen sulfide
  • ISO 9022-22, 1st Edition, Optics and photonics – Environmental test methods – Part 22: Combined cold, dry heat or temperature change with bump or random vibration
  • ISO 9022-23, 1st Edition, Optics and photonics – Environmental test methods – Part 23: Low pressure combined with cold, ambient temperature and dry and damp heat

Understanding EN expiration dates

April 2nd, 2015

Recently I had a customer who was told that an EN standard that he uses had expired and he should start using the previous edition.  Our client turned to us for clarification.  I figured that the information was not correct.  But of course, I researched it out because you never know…  It turned out that the source of the information was a person new to standards.  What was the real problem?  Not understanding EN expiration dates.

Here at Document Center Inc. we have a number of tools that we use for understanding the timelines for adoption and migration to the various editions EN standards.  And if there’s one thing that is always confusing, it’s understanding the EN expiration dates.  This information is found in the Harmonized Lists, so let’s go to the Harmonized List for Directive 93/42/eec on Medical Devices.

Let’s scroll down until you get to the section labelled: Summary list of titles and references harmonised standards under Directive 93/42/EEC for Medical devices.  This information is presented in tabular format, with a series of 5 columns of data and a separate row for each EN standard.  Column 1 tells you which of the European Standards Organizations (CEN, CENELEC or ETSI) are responsible for each document.  Column 2 is the document number itself and its title.  Column 3 is the first publication date in the OJ, the Official Journal of the European Union, which is the date when the standard is officially accepted onto the harmonized list.  Column 4 provides you with the information on what standard, if any, is replaced by the one in column 2.  So this might be the previous edition, or it might be a similar document but one with a different number.

However, the confusion that many people run into is with the data in column 5 on the far right, “Date of cessation of presumption of conformity of superseded standard.”  This is sometimes referred to as the expiration date.  This date is not the expiration of the document in column 2.  It is the expiration date of the standard in column 4.  Thus, you use this column to see when you have to complete your migration from 1 document or edition to the next.

Why do they call this “cessation of presumption of conformity?”  The harmonized standards have been developed specifically for a program called the New Approach.  In this system, regulators request one of the European Standards Organizations to develop a standard to meet specific requirements of a directive.  So for the List of Harmonized Standards for 93/42/eec, all documents on this list were prepared by a standards body specifically upon request of the regulators.  These regulators then accepted the documents (after review) with the publication of a notice in the OJ (the first publication date mentioned above).

Now, the essential benefit of this Harmonized List and the New Approach is what’s called “presumption of conformity.”  This is the concept that when you meet the requirements of a standard on the harmonized list, you meet the requirements of the applicable directive (in this case 93/42/eec).  So if you can find a harmonized standard and meet it’s requirements, your product can be easily certified for sale within the European Union.

However, the list does change as new standards are accepted by the regulators, especially when new revisions are released.  You, as a user of the standard, know that just because a new standard is available, that doesn’t mean that you can update your products and processes overnight to meet new requirements.  How much time will you legally have?  For the European Union, you’ll use the expiration date or cessation date as the time limit for compliance with the new material.

Is the cessation date always the date by which you must comply?  In the note at the bottom of the table, you’ll see that in special cases additional time may be allotted.

Is publication on the Harmonized List always proof of conformity?  Well, it used to be.  However, as the system matures, there are a few cases when this presumption of conformity for some standards has been called into question.  If this is a case for one of the standards you use, you’ll need to do additional work to “bridge the gap.”

Understanding EN expiration dates is essential to the proper use of these publications, but it can be confusing.  Document Center Inc. is a trusted resource you can turn to for information and clarification of these types of standardization questions and issues.  So not only can you purchase standards at our Document Center webstore at, you can turn to us for additional services to improve the way you use your compliance documentation.  We’re your Standards Experts!

ISO 7494-2 Updated

April 1st, 2015

ISO 7494-2, “Dentistry – Dental units – Part 2: Air, water, suction and wastewater systems,” has just been updated.  The new 2015 2nd Edition is available now from Document Center Inc.  You can get a copy in paper format, as a pdf download, or as part of our multi-user Standards Online subscription service.  The new update replaces the previous 1st Edition from 2003, which is now obsolete.  It also replaces the ISO 11144, “Dental equipment – Connections for supply and waste lines,” and partially replaces ISO 10637, “Dental equipment – High- and medium-volume suction systems.”

So, what’s ISO 7494-2 all about?  Well, I was surprised the other day when I went in for a routine teeth cleaning.  My hygienist didn’t give me the usual little paper cup of water for rinsing out my mouth, but relied solely on her suction device.  “Why?” I asked.  Of course, the answer was simple.  My saliva is classified as a bio-hazard!   So this means that the systems in any dentist’s office that provide air, water, suction, and waste removal need to be designed for both functional and sanitary requirements.

You’ll notice right from the start that the scope of the document has been expanded (The title of the 1st Edition is “Dentistry – Dental units – Part 2: Water and air supply.”)  The new edition is also 32 pages in length compared to the previous 16 pages.  Between the covers, you’ll find that it is a complete overhaul of the document.  The requirements clauses have been expanded from Clauses 4 to 7 in the 1st Edition to Clauses 4 to 9 in this new 2nd Edition.  The new material covers Sampling and a Technical Description.  And the other clauses have also gone through an update as well.

One thing to be aware of is the intention of the committee TC106 subcommitte SC6 (on dental equipment) to now work on requirements specifically directed to the microbiological aspects of fluids (my biohazards!) transported by dental units.  You should expect standardization to follow for the prevention, inhibition, and removal of dental unit waterline biofilm.  And other projects may follow.

FYI:  Currently the ISO 7494 series consists of just two publications: ISO 7494-1, 2nd Edition, “Dentistry – Dental units – Part 1: General requirements and test methods,” and the Part 2 reviewed here.

If you design and/or manufacture such equipment, you’ll want to get a copy of this new publication as soon as possible.  Order online at the Document Center Inc. webstore,  Or contact our staff for more information by phone (650-591-7600), fax (650-591-7617) or email (  We’ve been working with standards since 1982.  Take advantage of our expertise by making us your Standards Experts!

New IEC 62220-1-1 – Digital X-Ray Imaging Devices

March 31st, 2015

IEC 62220-1-1, “Medical electrical equipment – Characteristics of digital X-ray imaging devices – Part 1-1: Determination of the detective quantum efficiency – Detectors used in radiographic imaging,” has just been released.  This new publication replaces the IEC 62220-1, which is now withdrawn and obsolete.  It brings the conversion of the old 62220-1 into a 3 part series to completion.  And it is available from Document Center Inc. in paper format, for pdf download, and as part of our Standards Online multi-user subscription service.

As with many tools, digital x-ray imaging is fast overtaking older analog devices.  The IEC 62220-1 series defines the parameters describing the specific imaging properties and standardizing the measurement procedures to be used with this new equipment.

Of course, your next question is what is “detective quantum efficiency?”  Also known as DQE, it describes the ability of the imaging device to preserve the signal-to noise ratio from the radiation field to the digital image.  It really is a ratio of two noise power spectrum functions.  Why do you need to know it?  It’s used to describe the dose efficiency of a given digital x-ray device.  How widely is DQE used?  You’ll find this ratio referred to by manufacturers to describe equipment performance and in regulatory requirements (like those of the FDA).

What does the part 1 cover compared to the other 2 parts of the series?  IEC 62220-1-1 is for all detectors in digital radiographic imaging except those for mammography, found in IEC 62220-1-2, and dynamic imaging, found in IEC 62220-1-3.   In addition it should not be used for dental radiography, slot scanning devices or computed tomography.

What are the main updates from the IEC 62220-1 to the new IEC 62220-1-1?  Subcommittee 62B on diagnostic imaging equipment provides the following information for the user in the introductory material:

  • Revisions are included that have resulted from input from IEC 61267, “Medical diagnostic X-ray equipment – Radiation conditions for use in the determination of characteristics.”
  • Lag and ghosting compensation are now both addressed in the method for determining lag effects.
  • The method for determining MTF (modular transfer function)  has been restricted to only include the averaging of the ESF (edge spread function.)
  • There’s now a description of obtaining the diagonal MTF and NPS (noise power spectrum.)

New SAE J2894/2 – Plug-in EV (Electric Vehicle) Chargers

March 30th, 2015

SAE’s Hybrid – EV Committee has just issued another in their series of ground vehicle standards on electric vehicles.  This new SAE J2894/2, “Power Quality Test Procedures for Plug-In Electric Vehicle Chargers,” should be used in tandem with the SAE J2894/1, “Power Quality Requirements for Plug-In Electric Vehicle Chargers.”  The new Part 2 provides you with test procedures for both quality and efficiency.

What is the rationale for the J2894 standards?  SAE members and others realized that the rising sales of EV’s (Electric Vehicles) has the potential to put new (and possibly unexpected) strains on the electrical grid.  In addition to the pull of power — potentially at peak periods, there are also concerns about the possibilities of electromagnetic interference and other harmonic distortions.

Why was the scope of the Part 2 expanded beyond that of the Part 1?  The industry is developing at a rapid pace.  Folks who are using the standard needed complete guidance to meet both state and federal requirements that are different than those of 2011.  So the document now supports system level analyses for processes appropriate to 2015.

How does the SAE J2894/2 work?  The standard sets out a boundary system.  In this system boundary, the parts of the battery charging system included for evaluation are the EVSE (electric vehicle supply system), the battery charger (BC), the system powering auxiliary loads, and the battery.  The system boundary for most of the systems expected to be evaluated using this Recommended Practice is shown in Figure 1.  Then J2894/2 defines the tested elements and the measurement points.  You analyze the information that results from your testing to evaluate efficiency and response to events.  FYI: Some systems may require multiple measurement points to capture all auxiliary loads.

How can you get your copy of this new J standard?  Order from Document Center Inc., an authorized distributor of  the SAE Standards.  You can purchase your copies online at our webstore,, in both paper format and for pdf download.  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  We have been providing folks like you with standards from our Silicon Valley headquarters since 1982.  Make us your Standards  Experts!

New NDT Standard ASTM E543 2015 Edition

March 27th, 2015

ASTM E543, “Standard Specification for Agencies Performing Nondestructive Testing,” has just been updated and the new 2015 Edition is available now from Document Center Inc.  The standard is used to assess the competence of any public, independent or in-house NDT facility.  It was developed so that when nondestructive testing is part of the purchasing requirements, there’s a methodology for assuring the customer that the testing is done properly.

This specification covers your requirements from A to Z.  Clauses cover:

  • The organization of the “agency” (the testing facility)
  • It’s responsibilities and duties (what kind of testing it’s qualified to do)
  • Personnel requirements and Certifications
  • Requirements for a procedure manual
  • Equipment (included in mandatory Annex A1)

Appendix X1 is a chart that compares selected NDE methods (provided for your information only, not as a requirement).    This is particularly helpful since many ASTM NDT specifications are called out in the reference documents section.  This will help you choose the appropriate tests and standards.

Since this specification sets out the minimum requirements for NDT facilities, it is entirely possible to expand your requirements as necessary.  It is expected that this would be done in the purchasing contract.

If you’re using the ASTM E543, you’ll want to know what the changes are.  The committee E07 has provided you with the following information at the end of the document:  Subclauses 9.4.3 and 9.4.4 have been revised.  And of course, you’ll be needing a copy of the 2015 Edition in order to stay current with this material.

Head to the Document Center Inc. webstore at to order a copy in either paper format or as a pdf download.  Want multi-user access to this ASTM publication?  Contact our staff about setting up an account for our Standards Online subscription service.  It’s an easy way to maintain your conformance documentation and offer your staff convenient access any time, any where.  You can reach us by phone (650-591-7600), fax (650-591-7617) or email (  Make Document Center your Standards Experts!

New ISO/TR 80001-2-7 – IEC 80001-1 Compliance for HDO’s

March 26th, 2015

ISO/TR 80001-2-7, “Application of risk management for IT-networks incorporating medical devices – Application guidance – Part 2-7: Guidance for Healthcare Delivery Organizations (HDOs) on how to self-assess their conformance with IEC 80001-1,” has just been released.  As part of the IEC 80001-2 series (also composed of some ISO 80001-2 documents), it helps you address the issue of risk within an IT network that includes medical devices.  It’s been written for organizations such as hospitals, managed care facilities, surgical centers, behavioral health care facilities, and the like.  It allows such facilities to self-assess to IEC 80001-1, “Application of risk management for IT-networks incorporating medical devices – Part 1: Roles, responsibilities and activities.”

Does ISO/TR 80001-2-7 have any additional requirements not included in IEC 80001-1?  No, it is used to facilitate the application of IEC 80001-1 where it has been determined to be applicable.  It contains a set of questions that you can use to assess the performance from a risk perspective of your medical IT network.  And you can tailor the approach to meet your specific needs.

For example, you can use the assessment method of Clause 4 to audit your system to determine IEC 80001-1 conformance.  Or if you already know you conform, you can still use the assessment method to judge capability issues and your risk management processes.  Further, the assessment method is flexible so that it can be modified to meet the concerns of individual HDO’s.

What’s to be gained by using an internal assessment approach?  You’ll be able to spot current risk management weakness and will have a basis for improvement.  Or you might consider using it as a first-pass assessment to which you can add more stringent requirements as you move forward.

What will you find in ISO/TR 80001-2-7?  There’s guidance for the HDO self-assessment for IEC 80001-1 of course.  You’ll also get a set of questions to help you set up your assessment process for your medical IT-network from a risk management point of view.  It also will help you define a PRM (Process Reference Model) as required by IEC 80001-1.  And you’ll be able to set up a PAM (Process Assessment Model) that meets the requirements of ISO/IEC 15504-2, “Information technology — Software process assessment — Part 2: A reference model for processes and process capability.”

What are the stages of this ISO/TR 80001-2-7 assessment method?  Here are the stages that are required:

  • 1 – Defining assessment scope
  • 2 – Stakeholder involvement
  • 3 – Information collection and evaluation
  • 4 – Generating a findings report
  • 5 – Presenting the findings report

There are also a couple of additional optional stages:

  • 6 – Improvement planning
  • 7 – Follow-up assessment

There is no doubt that the reduction of risk in a patient-care setting is essential to the minimization of costs and liability, and the improvement of patient outcomes and satisfaction that are critical in today’s changing healthcare environment.  So those of you responsible for quality in an HDO setting will want to review this timely technical report now.

Where can you get your authorized copy?  Try the Document Center webstore at  You can order ISO and IEC standards in both paper format or for pdf download.  And they are available as part of our multi-user subscription service, Standards Online.  Contact our staff by phone (650-591-7600), fax (650-591-7617) or email ( for more information.

New IEEE C63.7 2015 Edition

March 25th, 2015

IEEE C63.7, “American National Standard Guide for Construction of Test Sites for Performing Radiated Emission Measurements,” has just been updated.  The 2015 Edition is available now from Document Center Inc. in either paper format or for pdf download.  It can also be included in our Standards Online subscription service for multi-user access.  The EMC standard is ANSI approved (the document used to be known as ANSI C63.7).  It’s been updated so that it can be used with the latest edition of IEEE C63.4 (“American National Standard for Methods of Measurement of Radio-Noise Emissions from Low-Voltage Electrical and Electronic Equipment in the Range of 9 kHz to 40 GHz” 2014 Edition).

Why would you use IEEE C63.7?  The standard provides you with the requirements for building test facilities to measure radiated emissions.  The facilities will be appropriate for testing electromagnetic emissions in the frequency range of 30 MHz to 40 GHz.  It is intended to be used with the other C63 series EMC standards.

Is there only one option for this type of testing facility?  No, you have several options depending on the frequencies you’ll be testing.  For 1 GHz and below, you’ll get the requirements for an open-area test site (OATS) and a semi-anechoic chamber (SAC).  For 1 GHz and above, you can choose from an OATS with absorber material or a SAC again with absorber material, in a number of surface configurations (one of which is called a fully anechoic room (FAR)).

What are the changes in this new 2015 Edition for IEEE C63.7?  The committee has highlighted the following areas where updates have occurred:

  • OATS with weather protection coverage are now included.
  • New provisions are introduced for SACs and FARs.
  • There’s updated to grounding for radio frequency low impedance and for human safety.
  • Of course, the coverage of the document has been expanded from 1 GHz to 40 GHz.
  • Links to useful URL’s are now included.
  • Annex C has been added (it cites the occurrences of “test site” in the C63.4 and C63.5).
  • Annex D, the bibliography, has also been expanded.

How can you get a copy of IEEE C63.7?  Go to the Document Center Inc. webstore at  You’ll have a choice of ordering IEEE C63.7 (paper format) or IEEE C63.7 PDF (pdf format).  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  They can help you with any questions or provide you a quote for multi-user access.  You have a choice, so remember to use Document Center for all your standards purchases and support services.  We’re your Standards Experts!

New ISO 5356-1 4th Edition Released

March 24th, 2015

ISO 5356-1, “Anaesthetic and respiratory equipment – Conical connectors – Part 1: Cones and sockets,” has just been updated.  The new 4th Edition is available now from Document Center Inc.  It can be purchased in paper format, as a pdf download, or for inclusion in our Standards Online multi-user subscription service.  Since it is a technical revision, the 4th Edition withdraws and replaces the 3rd Edition from 2004.

ISO 5356-1 is widely used for breathing attachments in anesthetic and respiratory equipment.  This is because in clinical practice there is often more than one device or items of medical equipment making up the breathing system.  The challenge is in providing connections for all these types of equipment that are interchangeable.   So the ISO 5356 series (both Parts 1 and 2) provide the manufacturers with specifications so that equipment from more than  one source will still work easily together.

If you use this standard, you’ll want to know what the changes are in this new edition.  The ISO committee 21 has provided you with guidance in the foreword to the new edition.  Here’s the highlights:

  • The revision makes the terminology consistent throughout both the title and text,
  • Updates to the definition section,
  • 11,5 mm cones and sockets have been included,
  • Modifications to the internal diameters of some cones
  • Significant changes to the requirements of 22 mm latching sockets and cones,
  • Corrections to Annex A, and
  • Restructuring of the document in order to make the text clearer.

FYI: There are no updates pending for the ISO 5356-2 on screw-threaded weight-bearing connectors at this time.

If you use this standard, you’ll want to get a copy of this new revision.  Order online at the Document Center webstore,  Or contact our staff by phone (650-591-7600), fax (650-591-7617) or email (  We’ve been an authorized distributor of the ISO standards since the 1990’s and offer a full range of services to support your use of compliance documentation.  Do like thousands of other companies do and make Document Center Inc. your Standards Experts!

ASTM D638 updated – Plastic strength test

March 23rd, 2015

ASTM D638, “Standard Test Method for Tensile Properties of Plastics,” has just been updated and the new 2014 Edition is available now at Document Center Inc.  Although the document was approved in 2014, it has just been made publicly available (published).  This is one of the most commonly used test methods for determining the strength of plastic.  It tells you how to test the strength of a plastic specimen in the shape of a dumbbell or dogbone in specific conditions, including temperature, humidity, and testing machine speed.

The test is basically executed by putting your specimen into a test machine that basically pulls the sample apart.  It’s held in place by grips and measurements are made as this process is taking place.  You then use your data to determine your results.

One thing to realize with a standard like this is that those results can vary depending on a number of factors.  So ASTM is clear in pointing out where these variations can occur and what you must do if your application requires more precise results.  The committee has also provided caveats for those who want to use the test for engineering design.

You’ll want to note that if your material is thinner than 1.0 mm (0.04 inches), you’ll need to use the ASTM D882.  And if the specimen is thicker than 14mm (.55 inches), you’ll have to reduce the thickness by machining.

Since ISO 527-1 is a similar standard, there is the question of interchangability.  The answer? They are not.   ASTM D638 and ISO 527-1 cover the same subject matter, but they are different in the technical content.  This divergence occurred when the ISO 527-1 was updated in 2012.

Now to take a look at where the changes are in this new 2014 Edition, since it cancels and replaces the previous 2010 issue.  The authoring committee, ASTM D20, has put a list of updates at the end of the document.  You’ll see that:

  • Note 1 has been revised, since ISO 527-1 is no longer equivalent (the changes that happened when the 2nd Edition of ISO 527-1 was released).
  • Updates have happened in some areas of the standard to eliminate permissive language
  • Editorial changes have also been made
  • Tables 2, 3, 4, and 5 have been moved to Section 13 (Precision and Bias)
  • And of course, the summary of changes has been changed!

If you use this standard, you’ll need to get a copy of the new D638-14!  Order online at the Document Center Inc. webstore,  You’ll have the option of ordering a paper copy or getting a pdf download.  Want multi-user access?  Check in with our staff about our Standards Online subscription service.  You can reach them by phone (650-591-7600), fax (650-591-7617) or email (  Document Center has been an authorized distributor of ASTM standards since the 1980’s.  You’ll notice the difference when you take a look at the revision history of the standards you’re interested in.  So make us your Standards Experts!
