MIL-DTL-901 Revision E is Shock Test Update

MIL-DTL-901 Revision E has just been released as the update for MIL-S-901.  This important test specification is titled Shock Tests, H.I. (High-Impact) Shipboard Machinery, Equipment, and Systems, Requirements for.  It is available from Document Center Inc. now in paper format, for pdf download and as part of our Standards Online cloud access service.

This specification has not been updated since 1989.  The new MIL-DTL-901 is an extensive revision of the previous edition, which is now obsolete.  It is specifically for high-impact shock test requirements for machinery, equipment and so on.  These systems and structures are to be used aboard surface ships, including carriers.  Submarines are also in this category.  Why use this test?  To make sure on-board equipment and systems can withstand the impact of shocks that might occur during operation or attack.

The MIL-DTL-901 is now officially a detail specification. This means that there are unique requirements in this document that cannot be met using various industry documents.  Additionally, the specification lays out in detail exactly how to perform the required tests, including test equipment and so on.  The redesignation of the number from MIL-S-901 to MIL-DTL-901 confirms the upgrade.

In reviewing the changes, I note that the previous Revision D was only 83 pages while the new Revision E is 142.  The new edition is in a modern format, with a table of contents missing in the earlier edition.  The text is much clearer now that the document is no longer a reproduction of a type-written original.  The figures at the end of the publication are clearer and cleaner.  And an Appendix A, Example of Shock Response Frequency (SRF) Calculation, has been added.

ANSI X9.24-1 Updated for Retail Transaction Security

ANSI X9.24-1 has just been updated.  The standard is titled Retail Financial Services Symmetric Key Management Part 1: Using Symmetric Techniques.  This new 2017 Edition is available from Document Center Inc. now.  It replaces the previous 2009 Edition, which is now obsolete.

ANSI X9.24-1 provides retailers with information on using what are known as symmetric keys for transmitting financial information securely.  Part 1, this document, specifically addresses symmetric techniques.  Part 2 deals with asymmetric ones.

What function do these type of keys provide?  While the protocols for the transmission of this type of data is publicly known, the key information is unique to each transaction.  It is the use of the protective procedures and features of this standard and it’s partner publication that makes each transmittal secure.

This standard establishes the requirements and guidelines for managing keys securely.  It also addresses application-level interoperability of your keying operations.  It is intended to be used with two NIST protocols.  The first is TDEA (Triple Data Encryption Algorithm) and the second is AES (Advanced Encryption Standard).

ANSI X9.24-1 can be used for any number of types of messages needing encryption.  Some examples include ATM and POS systems (retail Point-of-Service) transactions.

The 48-page standard was developed with help from many of the premier financial organizations, including banks, credit card companies, and financial software providers.  Many other technology companies also took part in this committee.  And of course, RSA the Security Division of EMC — the company founded by the original encryption developers — also participated.

Why has the ANSI X9.24-1 been revised?  First, it was reviewed as part of the required ANSI 5-year standards cycle.  During this process, the document was significantly updated.  Some items addressed in the new issue are updates for key management security requirements, the inclusion of AES algorithm use, and advances in hardware devices used to protect cryptographic keys.  Also note, a Part 3 is in the works.  It will have implementation details for TDES and AES DUKPT.

ASTM D6300 updated for Precision and Bias of Petroleum Tests

ASTM D6300 has been updated (again!) and the new revision is available now from Document Center Inc.  The 2017 Edition is titled Standard Practice for Determination of Precision and Bias Data for Use in Test Methods for Petroleum Products and Lubricants.  During the last several years, the standard has been revised one or more times annually.

What are precision and bias?  Precision is how specifically determinability, repeatability, and reproducibility can be achieved.  Bias is defined as the estimate of the systematic error, that is the degree to which estimates fail to meet reality.  Bias comes in two flavors, relative and absolute. Absolute bias is the difference between the estimate and reality.  Relative bias is the difference divided by the reference value.

The ASTM D6300 addresses these issues for petroleum test methods.  It specifically covers issues that crop up in the preparation and planning of interlaboratory programs.  And as noted, the concepts of precision and bias are statistical concepts necessary in laboratory conditions where results can be affected by a number of variables.  They are used to better understand the effects of potential sampling problems.

Changes in this new revision are highlighted in the redline edition.  Terminology (Section 3) has been revised, including a new Note 2. And subscription 8.4 has also be updated.  The redline edition shows each change both as a black line in the margin and with “marked up” text.  Please note: when you purchase the redline edition you also get a clean copy of the new publication.

FYI:  ASTM is a major developer of petroleum standards.  It frequently works with the Institute of Petroleum (based in the UK).  Recently some of their joint publications have undergone administrative changes.  So the ASTM D6300, ASTM D3244, the RR:D02-1007, and the ISO 4259 have been reorganized.  At this point, the RR:D02-1007 can be considered to be replaced by this ASTM D6300.  And the D6300 does differ from the related sections of the ISO 4259.

ASTM standards are copyright and can be purchased with confidence from Document Center Inc., an authorized distributor.  You’ll have a number of purchasing options, from paper format or pdf download to company-wide online access.  Order at our webstore,, or contact us by phone (650-591-7600) or email (  Here is a direct link to the order page for the ASTM D6300 latest edition.

EN 16935 Released for Information on Bio-based Products

There’s a new standard EN 16935 out and it’s available from Document Center Inc. now.  It’s titled Bio-based products. Requirements for Business-to-Consumer communication and claims.  It’s a European standard for the business-to-consumer communication of the characteristics of bio-based products.

What are bio-based products?  These are products made from plants and other renewable agricultural, marine, and forestry materials.  Of course, there’s many lotions and other cosmetics made from plants.  But now there’s also alternative fuels, bio-plastics, lubricants, candles and a host of other products in this category.

Bio-based products are gaining increasing market share as companies and customers look to reduct their environmental impact in terms of biodegrability, toxicity, and pollution.  Since bio-based products do not rely on petroleum, they have the potential to help reduce our carbon footprint.

What does EN 16935 address?  This new document has requirements for  a transparent and non-misleading business to consumer communications using labeling and claims.  This information centers on the characteristics of bio-based products themselves.  The standard should be used as a tool to generate and transfer this type of data to the consumer.

There are additional expectations for the EN 16935.  The European Standard is intended to be used as an input for product-specific standards and certification schemes in the future.

How can you get a copy of the new document?  You’ll have a wide array of choices since each European nation will publish their national edition as they adopt the standard.  Currently, the English language edition is available from Document Center Inc.  Here is the order page for the BS EN 16935 for your convenience.  Over the next couple of months, additional editions will become available.  You can search for and order them at our Document Center webstore,

If you’d like to know more about available standards for bio-based products, please see our Document Center Inc. List of Standards on Biobased Products.  It’s one of our many lists of standards on specific topic areas.

ISO 17361 Updated for Lane Departure Warning Systems

Is your car getting “smarter?”  If so, ISO 17361 on lane departure warning systems (LDWSs) may be partially responsible.  The standard is titled Intelligent transport systems – Lane departure warning systems – Performance requirements and test procedures.  It has just been revised and the new 2nd Edition is available now from Document Center Inc.

LDWSs help you keep your vehicle in your lane on highways and such.  The ISO 17361 is specifically for the warning system.  It does not address the use of automated action to avoid collisions.  This type of  warning system is intended to prompt the driver back into the lane when inattention causes “drifting” in the lane.

So you’ll find information on what such a system should consist of, various classifications of these systems, your human-machine interface (HMI) and test methods you can use to test your LDWS.  What kinds of things does this include?  Well, for example figure 1 addresses the concept of warning thresholds and warning threshold placement zones.   This helps you define the lane boundary, with specific outside zones that delineate the earliest warning line and the latest warning line.

The 1st Edition of the ISO 17361 was released in 2007.  This new 2nd Edition is a minor revision, but it does cancel and replace that previous document.  The committee notes the following changes:

  • Clause 2 has been updated
  • The Annex a has been deleted (you’ll use ISO 11270 instead in subclause 3.2)
  • Unicode is now used for the previous inequality signs

You’ll need the 2nd Edition if you use this publication.  Purchase an authorized copy from Document Center Inc. at our webstore,  Here is a direct link to the order page for ISO 17361 for your convenience.  And you may also want to take a look at our Document Center Inc.

ISO 18415 for Microbiological Examinations of Cosmetics Updated

The ISO 18415 cosmetics standard has just been updated.  You can get your copy of this new revision from Document Center Inc.  Your authorized purchase can be made in paper format or for pdf download.   Cosmetics – Microbiology – Detection of specified and non-specified microorganisms 2nd Edition cancels and replaces the 1st Edition from 2007.

Standards serve a very public service in assuring us that the products that we purchase are safe.  Indeed, quality and safety are two of the most important factors in standards development.  There are many products that we don’t particularly associate with standards.  Yet in areas like cosmetics, standards have an important role to play.

One of these is the determination of microbiological risk and protocols for reducing those risks.  Since cosmetics can harbor pathogens that cause infection, it is essential that cosmetic developers and manufacturers be vigilant.  And special care must be taken to avoid contamination during the manufacturing process itself.

ISO 18415 gives you guidelines for the detection and identification of specified microorganisms in cosmetic products.  You’ll be using a method that involves the use of a liquid medium for detection of microbial growth.  Any microorganisms can then be isolated using an agar media. Details on identifying these micoorganisms are included.  You’ll also find information on specific tests and test equipment.

Those of you already using the document will want to know about the changes in this second edition of ISO 18415.  The committee has provided you with information in the Foreword to the standard.  First, it notes that this is considered a “minor” revision.  Changes can be found in:

  • The scope section
  • Section 3.8
  • Clause 4
  • Sections 5.1, 5.2.1, and
  • Sections 11.3.1, 11.3.2, 11.3.3
  • Clause  12

Most of these updates center on a change to the concept of “validation.”
