ASTM A276/A276M updated – Stainless steels

ASTM A276/A276M, “Standard Specification for Stainless Steel Bars and Shapes,” has been updated.  The new 2016 Edition has just been released and it replaces all earlier editions, including the previous 2015 Edition from January 2015.  This is an essential standard covering hot- or cold-finished stainless steel bars and shapes.  Reforging and free-machining types are not included.

As with all ASTM standards with a dual designation (A276 and A276M), the specification provides you with measurements both in inch-pound and SI units.  Since values are not  exact equivalents in moving from one to the other, you will need to be consistent in which measurement system to use.

The specification is divided into two major sections, each with it’s own table.  First comes the chemical requirements, listed by UNS numbers.  This gives you the percentage of the various metals that compose each UNS metal alloy type.  Table two provides you with the mechanical requirements, again listed by UNS number.  A short Table 3 covers the response to heat treatment.  And of course, there’s the balance of the technical information — ordering information, manufacture, magnetic permeability, certification and the like.

Those of you who use the ASTM A276/A276M will want to know where to find the changes.  Your committee A01 has provided you with a “Summary of Changes” at the end of the publication.  This is your guide to where to look for your updates.

First, there is a new UNS type added to both Tables 1 and 2.  You’ll find this also in section as a stabilized anneal condition.  There is also a new footnote K in Table 1.  And another revision to Table 1 has been made to Grade S32750 (the additional of footnote L).

Of course, if you use this specification you’ll want a copy of the new 2016 Edition.  You can purchase it in paper format or for pdf download at the Document Center Inc. webstore,  Here is the direct link to the ASTM A276/A276M order page.  And as an authorized distributor of ASTM Standards, we also offer the specification as a redline edition or as part of our Standards Online multi-user subscription service.  Just contact us for more information by phone (650-591-7600) or email (  We’re here to help you use your standards more effectively and with confident.  Make us your Standards Experts!

Why was AN 960 cancelled again?

What?  The AN 960, “Washer, Flat ,” has been cancelled again?  The new Cancellation Notice 2 for the 21st Revision was just released.  Since AN 960 was already cancelled in September 2011, you may be wondering why they decided to cancel it second time.  Good question!  And yes, the publication is still replaced by NAS 1149, “Washer, Flat.”  So there’s nothing to worry about in that department…

NAS 1149 was originally released in 1990 and adopted by the DoD (Department of Defense) in 1992.  At about the same time, the last Revision 21 for AN 960 was released.  And guess what!  The Revision 21 was deemed “inactive for new design” with the direction to use the NAS 1149 for all new projects (a substitution in all applications.)

So actually the cancellation of AN 960 in 2011 was a transitional cancellation — It still allowed for the use of existing stock until that stock was deleted.  However, a number of years have passed since then.  So the new Cancellation Notice 2 no longer contains that “depletion of existing stock” language.

Instead, the new notice 2 contains the cross-reference tables to help you identify the original AN 960 PIN (Part or identifying numbers) and match it to the replacement NAS 1149 PIN.  It appears to be the same information as before, just without that “escape clause” regarding the use of material that was made to the old specifications.

You can think of this new cancellation notice as “closing the loop.”  It finally completes the transition from one document to the other, and from a now-obsolete air force-navy drawing to an industry specification.

How to get copies of either the AN 960 or the NAS 1149?  Head straight to Document Center Inc.  Our webstore is at and enables you to order government and industry specifications from one location, as well as both current and obsolete documents.  Here is a link to the order page for AN 960 and a link to the order page for NAS 1149.

What are FDA Guidance Documents?

What are FDA Guidance Documents?  Why should we use them?  Do they have any legal weight?  These are questions that many organizations have when trying to understand FDA compliance and how the FDA works.  Since FDA Guidance Documents contain a wealth of information that many of our Document Center customers find to be very helpful, I’m going to discuss these publications in general today.  My goal?  To give you a better idea of when and how to use them to improve the way you interact with the FDA.

Guidance Documents are published by the FDA on a regular basis.  They are a methodology they use to communicate information about FDA processes and regulatory requirements.  These publications do not have any legally binding status.  They just are a way for the FDA to let you know what their current thinking is on a topic or how they deal with certain issues or about new processes that you’ll be asked to meet.

One area that FDA guidance documents cover is submissions: how to make your submissions, how your submissions will be reviewed, what they should contain, and so on.  If you’re unfamiliar with what documentation you  need to provide and how it will be processed, guidance documents can explain this to you in general terms.  And occassionally you’ll even get an overview of a specific issue for submissions, as when the “Refuse to Accept Policy for 510(k)s – Guidance for Industry and Food and Drug Administration Staff” was recently released.  This document covers a specific situation for submissions, what it means and how to deal with it.

Another area that’s addressed is compliance, inspection and enforcement.  For anyone with FDA regulatory requirements, understanding how an inspection can take place and what the inspector(s) will be looking for is critical.  Promoting compliance with regulatory requirements over time is an important aspect of the FDA’s mission.  So you’ll find such publications as “Unique Device Identification System: Small Entity Compliance Guide – Guidance for Industry and Food and Drug Administration Staff” available to help you in this regards.

And the other main area that’s covered by guidance documents are about the regulated products or processes themselves.  You’ll find information in these publications on design, production, labeling, promotion, manufacturing, and testing.  They’re a critical communications tool for the FDA.

Some are issued for products that are “hot” as when there was some concern over sterility processes for endoscopes recently.  The FDA issued an update for it’s publication “Reprocessing Medical Devices in Health Care Settings: Validation Methods and Labeling – Guidance for Industry and Food and Drug Administration Staff” to help resolve this issue.  And alongside the FDA’s guidance release, standards organizations also looked to improve processes defined by standardization for this topic.

Others are issued when the FDA or industry perceive that additional information is required to get the desired level of safety and reliability necessary for the public’s well-being.  These can be about very specific topics or more general, like the recent “Premarket Notification Requirements Concerning Gowns Intended for Use in Health Care Settings – Guidance for Industry and Food and Drug Administration Staff.”

So, as we mentioned before, FDA Guidance Documents are not a requirement, but they can offer medical device developers and manufacturers a wealth of information to improve the way that you interact with the Administration.  If you’re in this industry, you should monitor these publications on a regular basis.  One easy and effective way to do so is to review the on a regular basis.  Just yesterday, I posted the new Medical Device Guidance Documents that were released during the 4th quarter of 2016!  Check it out.

And don’t forget:  Document Center Inc. not only provides you with the standards you’ll need but also gives you access to regulations and supporting documentation necessary to achieve compliance and safety in your product line.  Order the material you need at our webstore,  Or if you have additional questions, reach us by phone (650-591-7600) and by email (  We’re here to support your quality and compliance requirements!  Make us your Standards Experts!

New IPC-A-610 F Amendment 1

IPC-A-610, “Acceptability of Electronic Assemblies,” has just been updated.  There’s a new Amendment 1 available for Revision F and you’ll want a copy if you use this important electronic assembly standard.  It is being issued in conjunction with a new Amendment 1 for the J-STD-001 so you may want to get both amendments at the same time.

IPC-A-610 is one of the most frequently ordered assembly standards here at Document Center Inc.  So the new Amendment 1 is big news.  Here are the changes as specified by IPC:

  • Reintroduce the Space Shuttle symbol to show where there are different criteria in the J-STD-001FS, “Space Applications Electronic Hardware Addendum” to IPC J-STD-001F, “Requirements for Soldered Electrical and Electronic Assemblies”
  • Revise the Class 2 requirements for vertical solder fill on plated through holes with less than 14 leads to include requirements when there is a connected internal thermal plane
  • Eliminate requirements for BGA voiding for BGA components with noncollapsing balls

RR-W-410 H released for Wire Rope and Strand

RR-W-410, “Wire Rope and Strand,” has been updated.  The new Revision H cancels and replaces the previous Revision G from June 2010.  The new update for this Federal Specification can be procured in both paper format and for pdf download from Document Center Inc.  It is used in many organizations across the U.S. — both for government contract work and general specifications for the product.

Federal specifications like RR-W-410 are written and maintained to provide the requirements for products purchased by the federal government.  They may not include all types and classes that are in commercial use, but they certainly provide you with the details of items called out in U.S. government contracts.

In this case, the specification covers wire ropes and wire seizing strands, with information on the types, classes, constructions and sizes required.  First comes a detailed list of all the wire rope types and sizes that are addressed in this document.  Next general requirements are reviewed.  This Clause 3 is lengthy, including things like the types of materials that can be used, workmanship, tensile strengths, and so on.  Clause 4 gives you the quality assurance requirements you’ll need to meet.  Packaging requirements are reviewed in Clause 5.  Clause 6 is a notes section.  It does tell you that the changes in the new Revision H are extensive, so there are no black lines in the margins to help you identify them.

The second half of the RR-W-410 is devoted to the various tables that are included to help you meet the exact dimensional requirements for the various types of wire ropes.  You’ll also find a series of figures in this part of the publication that are cross-sections of various types of wire rope, again to insure that you understand exactly how each type should be configured.

As a user of Federal specifications, you have a number of choices when getting your copies of these publications.  Consider using Document Center for your purchases, as you’ll get our free best-in-class notification service with each document you buy from us.  And if you’d like to have an online portal where all your staff can review and use the documentation necessary for compliance in your organization, ask us about our Standards Online subscription service.  All federal specifications can be included in this multi-user service.

BHMA A156.6 and BHMA A156.15 updated – for Doors

BHMA A156.6, “Architectural Door Trim,” and BHMA A156.15, “American National Standard for Release Devices – Closer Holder, Electromagnetic and Electromechanical,” have been updated.  The new 2015 Editions were released at the very end of the year and both replace and cancel the previous editions.  Copies are available in both paper format and for pdf download.  We’ll discuss each separately.

One thing to note, however.  BHMA does not provide you with any guidance within the document itself with regards to the changes in each of these updated publications.  So you will need to review each of these new publications carefully.

Now for basic information on BHMA A156.6 and BHMA A156.15:

BHMA A156.6 (aka ANSI/BHMA A156.6) 2015 Edition

This Standard covers such products as door protection plates, door edgings, push plates, door pulls, push bars, and pull bars. As a standard, requirements are provided for each of these types of “trim.”  You’ll find strength and finish tests, and dimensional and material criteria all included in this publication.  It is ANSI adopted.

BHMA A156.15 (aka ANSI/BHMA A156.15) 2015 Edition

BHMA A156.15 establishes requirements for door closers combined with hold-open devices or free-swinging door closers combined with releasing devices.You’ll find  performance tests included which cover operational, cyclical and finish criteria.  It also includes information on how to communicate requirements for installation and maintenance to your customer base as well.  And again, it is ANSI adopted as well.

Both BHMA A156.6 and BHMA A156.15 follow the same basic format:  A scope paragraph followed by definitions and then general information.   At this point the A156.6 then is divided up according to the various product categories (J100 for door protection plate, J200 for door edgings, and so on).  Next comes the finish tests and Appendix A (not enforceable requirements, but a discusssion of various points of interest for the various clauses of the standard.)  A156.15 on the other hand, reviews the steps involved in performance testing — from preparation through the testing itself and finish performance requirements.  Then there’s an explanation of the identifying numbers and, of course, a similar Appendix A, again with additional information to help you use the standard effectively.

ASTM E10 Updated again!

ASTM E10, “Standard Test Method for Brinell Hardness of Metallic Materials,” has been updated yet again!  The new 2015a Edition is available from Document Center Inc. now in both paper format and for pdf download.  And as I have mentioned before, ASTM standards that are updated frequently are perfect candidates for our multi-user Standards Online subscription service, since updates are posted to your account immediately with no additional charge.

Of course, I’ve described how the standard provides you with everything you need to know in order to conduct tests to determine the brinell hardness of various metallic materials in previous posts.  So it’s likely that you already use this standard in your operations.

I’m sure that you’re now interested in finding out what the changes are in the 2015a Edition that’s just been released.  But first, since I last reviewed the standard when the 2014 Edition came out, there’s a missing review of the 2015 Edition that has been in effect since July.  So let’s take a look at those changes first, and then we’ll review the 2015a changes after that.

In July, ASTM E10 had changes made to the Annex A.  These can be found is section A1.5.2.3, which covers how many hardness tests you need to make for the daily verification test blocks.

The new 2015a revision (approved by the committee at the beginning of December) is also a technical revision, this time updating the  calculation found in section 3.2.4, for determining the error E in the performance of a Brinell hardness machine.  Additionally, the section on tests for flat surfaces (7.6.3) has been modified.  The ambient temperature section has been updated (7.8).  And Table 5’s values have been completely redone (for the summary of statistical information).

This is indeed a change to the 32-page standard that you’ll want to review, so you’ll want to purchase your copy asap.  Go directly to the Document Center webstore to purchase an authorized copy.  It’s at  And here’s the direct link to the order page for ASTM E10!

And if you want to make sure that you’re able to identify all the changes, contact our staff and ask for the redline edition of this standard.  You’ll receive two copies, one with the mark-up provided by the committee and the other clean copy of the new edition.  Just check in with our staff for more information — you can reach them by phone (650-591-7600) or email (  We’ve been selling authorized copies of the ASTM standards since the 1980’s.  Make us your Standards Experts!

AMS QQ-P-416 for cadmium plating revised

AMS QQ-P-416, “Plating, Cadmium (Electrodeposited),” has just been revised and the new Revision E is available from Document Center Inc.  You’ll be able to purchase this new update in paper format or for pdf download.  It replaces the Revision D from July 2015 (now obsolete.)

AMS QQ-P-416 has come a long way since it migrated from being a Federal Specification to an industry standard.  Yet it continues to be a heavily used document throughout industry.  It is the go-to standard for electrodeposited cadmium plating and has been for years.

The update resolves a couple of issues.  First, there were some errors in Table 1a in the last edition and these have been corrected.  Additionally, the ’24 hour minimum’ has been removed from the drying time requirement of

As you can see, these corrections make this a technical update and one that you’ll need to purchase if you are complying to this standard.  How do you get your copy?  Head to Document Center’s web store at and order online.  Here’s the direct link to the order page for AMS QQ-P-416.

New MIL-STD-461 G for EMI control

MIL-STD-461, “Requirements for the Control of Electromagnetic Interference Characteristics of Subsystems and Equipment,” has just been updated with the publication of Revision G.  The last edition, MIL-STD-461 F, was released in 2007 so it’s been a while!  The new MIL-STD-461 G cancels and replaces the previous edition and needs to be procured for all of you whose DoD contracts call out the document.  And this is one of the Military Standards that is widely used throughout industry.

MIL-STD-461 G provides you with the interface and verification requirements necessary to control electromagnetic interference (EMI) emissions.  These emissions affect electronic, electrical and electrommmmechanical equipment and subsystems.  In this document, the focus is on those products purchased by the DoD (the U.S. Department of Defense).  And as part of the general DoD profile, DID (Data Item Description) requirements are also included.

MIL-STD-461 G is divided into two sections:  the main body of the standard and the appendix.  The first contains all the interface and verification requirements necessary.  The appendix, on the other hand, is not part of the contractual requirements of the document.  But it provides the rationale and guidance for the interpretation and use of the various requirements spelled out in the main body.  So you’ll find a parallel numbering scheme used in both sections.

OK, so you use MIL-STD-461 and you want to know what the changes are in the new 280-page Revision G.  Here’s what Clause 6.8 has to say about the update:

“This revision of the standard deleted CS106 conducted susceptibility, transients, power leads. In addition, this revision added CS117, conducted susceptibility, lightning induced transients, cables and power leads and CS118, personnel borne electrostatic discharge. Marginal notations are not used in the revision to identify changes with respect to the previous issue due to the extensiveness of the changes.”

Now to get your copy of the new standard.  You’ll find it available in both paper format and for pdf download at the Document Center webstore,  Please note that your purchase will include our best-in-class notification service at no additional charge.  This means that you’ll be sent an email each time the publication is updated.  Here’s a link to the order page for MIL-STD-461 G.

ASTM B633 2015 Released

ASTM B633, “Standard Specification for Electrodeposited Coatings of Zinc on Iron and Steel,” has just been updated.  The new 2015 Edition replaces the ASTM B633 2013 Edition which is now obsolete.  This is an technical revision to an essential plating spec, used throughout industry.  Here at Document Center we’ve sold hundreds of copies of the document over the years.  You’ll want a copy if you use this specification.

What exactly does ASTM B633 2015 address?  The specification covers the materials and processes to use for the electrodeposition of zinc coatings on iron or steel goods to protect them from corrosion.  It also includes information on the various tests you’ll use to confirm thickness, adhesion, corrosion resistance and so on.  This means the coating requirements and the sampling process (including specimen preparation) are part of the publication as well.

What’s new in the ASTM B633 2015 Edition?  An additional test has been added to give you another option when it comes to determining the thickness of the coating.  This means that there is one more ASTM standard included in the referenced document section as well.

How can you get your copy of this new ASTM specification?  Choose an authorized distributor of the ASTM Standards like Document Center Inc.  You can go directly to our Document Center web store at and place your order online.  Here is the link directly to the order page for ASTM B633 — It’s available in both paper format and for pdf download.
