ISO/IEC 19592-2 – How to share secrets!

ISO/IEC 19592-2 on sharing secrets has just been released.  It is the companion document to the ISO/IEC 19592-1.  OK…  This secret sharing scheme is a cryptographic technique.  It breaks up a message into parts along with a message sharing algorithm for dividing the message and another for putting it back together again.  The new ISO/IEC 19592-2 gives you the mechanisms to do this.  Both are available from Document Center Inc. now.

I blogged about the ISO/IEC 19592-1 when it was released last year.  The new Part 2 is titled Information technology – Security techniques – Secret sharing – Part 2: Fundamental mechanisms.  It specifies how you’ll go about setting up the actual sharing scheme. It will contain two functions — message confidentiality and message recovery.

The standard begins with the usual scope, referenced documents and definition sections.  There is an additional Clause 4 with symbols and abbreviated terms.  Then we move directly into secret sharing schemes themselves in Clause 5.  A number of schemes are reviewed.  These include Shamir and Ramp Shamir.  Additive, replicated additive, and computational additive are also included.  Two informative Annexes cover object identifiers and numerical examples.  An 8-item bibliography completes this 30 page document.

If you need to know how to share a secret, the ISO/IEC 19592 standards are for you.  Purchase your copies from Document Center Inc., an authorized ISO and IEC distributor.  You can find them at our webstore,  Here is a direct link to the order pages for the new ISO/IEC 19592-2 and the ISO/IEC 19592-1 for your convenience.

ANSI B11.20 – Safety for Integrated Manufacturing Systems

ANSI B11.20, the standard on Safety Requirements for Integrated Manufacturing Systems, has just been updated.  The 2017 (3rd) Edition replaces the previous 2004 Edition, which is now obsolete.  The committee recommends that you make the transition to this new edition within 30 months.  You can get your copy now from Document Center Inc. in either paper format or for pdf download. And it can be included in our company-wide access cloud service, Standards Online.

What is an integrated manufacturing system (IMS)?  It’s a shop floor layout that incorporates two or more industrial machines.  They manufacture, package, treat or move parts or assemblies.  They can operate independently of each other but are linked by a material handling system.  This control system results in coordinated operation.

Why do you need a safety standard for IMS’s?  To minimize the risk of injury to staff in this complex environment.  The number and types of risks are different when machines are operated in a coordinated fashion.  You should set up your safety system based on the installation, rather than on the hazards of each machine individually.

What’s new in this edition of the ANSI B11.20?  First, it is now harmonized with the ISO 11161.  The terms have been updated as part of an effort to set up consistent definitions for all of the B11 safety standards.  There are 2 new Annexes — Annex D on zone determination and span of control, and Annex E, special mode.  You’ll find significant updates toclauses 4, 5, 7, and 9.  Training will be impacted by new clause 10 and Annex F on general guidelines for operator training.  And there is also a new clause 11 for decommissioning.

Of course, Document Center Inc. is an authorized distributor of the ANSI B11 standards.  So you can search for and order them with confidence from our webstore,  Here is a direct link to the order page for the ANSI B11.20 for your convenience.

ISO 28590 – Inspection by Attributes

ISO 28590 and an additional seven standards in the series have just been released.  These are the new ISO standards on sampling for inspection by attributes.  The ISO 28590 is the overview standard, providing an introduction to what is called the “ISO 2859 series.”  The complete title of this new release is Sampling procedures for inspection by attributes – Introduction to the ISO 2859 series of standards for sampling for inspection by attributes.  It and the balance of the newly released series are available now from Document Center Inc.

Of course, here in the U.S. we’ve been using the ASQ-Z1.4 (previously the MIL-STD-105) for many years.  The ISO 2859 series is the European equivalent for this sampling procedure.  The two schemes are both current and can be referenced with confidence.

ISO released the ISO-2859 series back in the 1990’s.  However, with the October release of these new issues, some frequently-used ISO publications have basically been renumbered.  Here is a list of the changed references:

What are the primary changes to these documents?  The revised numbering to bring them all into a series format.  And don’t forget, the old ISO 2859 series standards (Parts 1 through 5) remain in force.

You may also wonder what the European equivalent is for the ASQ Z1.9 standard on inspection by variables.  This would be the ISO 3951 series.

Now to get your copies.  I’ve included links to the order pages in the list above.  However, you can also search for and order other quality standards from our Document Center webstore at  We are an authorized distributor of standards and have an extensive collection for you to choose from.

ISO/IEC TS 33073 – Process Assessment

ISO/IEC TS 33073 has just been released to help you set up a quality management process assessment model (PAM).  This is a set of indicators for process performance and process capability.  They are to be used to collect objective evidence for your assessor.  The PAM supported by this standard meets the requirements of ISO/IEC 33004.  It is available now from Document Center Inc.

The standard is titled Information technology – Process assessment – Process capability assessment model for quality management.  It is designed to support self-assessment for process quality.  You’ll use it as the basis for your on-going improvement cycle.  And it provides you with a methodology for an actual process rating.

No matter the size of your organization or the types of processes you use, you’ll find the ISO/IEC TS 33073 to be applicable.  The 308-page standard begins with the usual scope, referenced documents and definition sections.  Section 4 reviews the process assessment model (PAM) itself.  You’ll get an overview of the structure of a PAM, the assessment indicators, and measuring process capability.

Section 5 covers various process performance indicators, divided into types.  COM.01 through COM.11 are administrative (like management review and operational planning).  ORG.01, ORG.02, and ORG.03 cover asset management, measurement resource management and supplier management respectively.  The 11 TEC indicators deal with configuration and product/service issues.  A final TOP indicator is on leadership.  Each of the indicators is presented as a table, featuring critical features of each.

Section 6 provides you with information on process capability indicators.  This time they’re organized by levels, from zero to five.  Information is presented in a combination of text and tables.  You’ll see how to define your requirements, identify and establish objects and measurements, create documentation, and so on.  Overview tables of the processes and attributes will supply you with visual support.

The ISO/IEC TS 33073 contains 3 informative Annexes.  Annex A is on conformity of the PAM, Annex B covers input and output characteristics, and Annex C reviews the relationship between this standard and the ISO 9001 requirements.  An 11-item bibliography completes the standard.

You can purchase your copy of this new edition now at Document Center Inc.’s webstore,  Here is a direct link to the order page for ISO/IEC TS 33073 for your convenience.  If you are ISO 9000 certified, you’ll want to learn more about our support services.  Check in with our staff by phone (650-591-7600) or email (  We have a range of products and services to help every size business improve document compliance outcomes.  Find out why so many companies make us their Standards Experts!

ISO 14644-15 – New Cleanroom Standard

The ISO 14644-15 Cleanroom Standard has just been released.  It’s title is Cleanrooms and associated controlled environments – Part 15: Assessment of suitability for use of equipment and materials by airborne chemical concentration.  It’s intended to be used with ISO 14644-8.  You can get your copy now from Document Center Inc. in either paper format or for pdf download.

The ISO 14644 series of standards on cleanrooms is widely used throughout industry.  There are many manufacturing situations where a clean environment is essential.  Some involve classifying the cleanliness level by the concentration of chemicals in the air.  The ISO 14644-15 has been developed to assist users using this method.

One issue for those in charge of cleanrooms is the impact of bringing in “foreign” materials into the cleanroom environment.  Now the ISO 14644-15 gives you a methodology for controlling contamination.  It specifically addresses evaluating equipment and materials that will be introduced into your cleanroom.  This evaluation is for the chemical airborne cleanliness of these items.  If you determine cleanliness classes by chemical concentration per ISO 14644-8, this will be immensely valuable.

The new standard begins with the usual scope, referenced documents, and definitions sections.  Nine additional sections cover symbols, test setup, representative mode, visual inspection, a description of the test, calculation of the measured concentrations, calculation of the specific emission rate, the assessment itself, and your documentation.  There are also 3 informative Annexes and a 19-item bibliography.  The Annexes can help you evaluate such items as flooring and wallpaper.

To get your copy of this and any of the ISO 14644 standards, use the Document Center Inc. webstore at  We are an authorized distributor of the ISO standards so you can purchase with confidence.  Here is a direct link to the order page for ISO 14644-15 for your convenience.

ANSI Z535.1 2017

ANSI Z535.1, Safety Colors, is being updated and the new 2017 Edition is due in mid-December.  This new Edition will also impact the ANSI Z535 set of the 6 standards in the series.  Remember, if you have purchased the entire set, only the Z535.1 will be updated in December.  The new revision will be available from Document Center Inc. at that time.

ANSI Z535.1 includes the technical definitions, color standards, and color tolerances for safety colors. These are the colors that are used in safety signage and other warning material.  It provides a consistent way to communicate hazardous situations and environments visually.

The standard is widely used throughout industry.  It has even been adopted by the U.S. Department of Defense.  The standard was last updated in 2006, with reaffirmation of the contents in 2011.  So this new update will be important for many businesses and other organizations.

There’s no preview available for the new ANSI Z535.1 2017 Edition at this time.  So I’m unable to give you concrete information on the up-coming changes.  I will note however that the ANSI-Z535.4 is also under review.  So a new edition of that standard could also appear soon.

Now to get your copy of the new edition.  It’s available for pre-order now at our Document Center Inc. webstore,  Here is a direct link to the order page for the ANSI Z535.1 for your convenience.  Please note:  As I stated before, this new edition will also update the information for the Z535 set.  If you already own all 6 standards, you’ll only need to get the updated Part 1 in order to remain current.

Have additional questions?  Need to purchase other standards?  Want more information about all our support services?  Just get in touch.  We can be reached by phone (650-591-7600) or email (  We’ve been working with standards since 1982.  We’re your Standards Experts!

BS EN 55011 Corrected

BS EN 55011, the English language copy of the EN adoption of CISPR 11, has just been corrected.  The standard is titled Industrial, scientific and medical equipment – Radio-frequency disturbance characteristics – Limits and methods of measurement.  It was recently updated as the 2016 Edition with Amendment 1 from 2017.  An additional corrigendum (correction sheet) has just been released.  It is available from Document Center Inc. now.  If you already purchased the previous edition from us please let us know.  We offer a special deal for corrigendums for those of you who bought the standard from us.

This is not an unusual situation.  Most times the editorial review of a standard will catch mistakes prior to publication.  But occasionally, an error or two will make it into the final document.  Of course, usually the first users of the standard will spot a mistake and the standard is fixed.  However, we have had examples of customers finding errors years after a standard was formalized.

If you use BS standards, you’ll want to understand how to spot the revision history.  Look inside the front cover of the document.  There you’ll find a table at the bottom of the page labeled “Amendments/corrigenda issued since publication.”  For the BS EN 55011, you’ll see the implementation of the Amendment 1 on July 31, 2017.  And you’ll see the listing for the correction on October 31, 2017 as well.

A lovely feature of this table is that you’ll get information on each update.  For the corrigendum, it says “Supersession details in national foreword corrected.”  The bad news is that there is no further detail about what this means.

So in this case, you’ll look for the National foreward, which is on the same page as the table.  You’ll soon realize that the correction is very important.  In the 2016 Edition with Amendment 1, the standard correctly replaces the 2016 Edition.  But it also says that the 2016 Edition has been withdrawn.  Now in the corrected edition it shows that the 2016 Edition will be withdrawn on April 21, 2020.  This gives you additional time to make the transition from one edition to the next.

I hope you can see that corrigendums and other correction sheets can contain information critical to your proper use of a standard.  And if you’re using the BS EN 55011, you’ll want to get your copy now to keep your compliance documentation current.  Use the Document Center Inc. webstore at to purchase your authorized copy.  Here is a direct link to the order page for BS EN 55011 for your convenience.   We are authorized distributors of the BS standards collection, so you can buy with confidence from us.

How did you become a Standards Professional?

I was one of the mentor’s at ANSI’s Standards Simulation contest at San Jose State University last week.  And one of the questions students asked me was “How did you become a Standards Professional?”  In fact, ever since I have become involved in the standards community at large, this is a frequent question.  People want to know what career path leads to participation in standards activities.

Now the Asia-Pacific Economic Co-operation group APEC is going to find out!  Their Sub-Committee on Standards and Conformance (SCSC) is conducting a survey on this very question.  And best of all, if you take the survey, you’ll get a free copy of the results.

What is APEC’s Sub-Committee on Standards and Conformance?  The SCSC was established in 1994 to promote understanding and usage of standards in the Asia-Pacific region.  It was developed for a number of reasons.  First, this region has been very interested in using standards to facilitate international trade.  Second, Asia has been increasing participation in International Standards activities (ISO, IEC, and ITU).   Why?  For the sake of harmonization of standards in this area with international norms.  So a focal point for educational activities is warranted.  And lastly, greater reliance on standards promotes improved production integration with global partners.  All these activities have helped improve the economies of the APEC member countries.

What is the SCSC survey about?  The survey (located at is a questionnaire for standards professionals in both industry and in Standards Developing Organizations.  It aims to identify both the career path of standards professionals and map the reults.  It also asks about skills and the knowledge base required for those in the standards community.  In the end, the survey will be used to create recommendations for SCSC projects to inspire folks in the region to enter this field.

Who should take this survey?  Anyone who is a standards professional!  But you’ll need to act prior to December 15, 2017.  When the survey is complete you’ll get a copy of the survey summary results.  Since the company and individual information will not be publicly available, this is one of your few chances to gain access to this critical information.  It should be completed around March of 2018.

Hats off to APEC’s SCSC for undertaking this survey.  And also to Donggeun Choi from KSA (the Korean Standards Association) for taking the lead on the project.  We’re very interested in seeing the results of this work on “Inspiring the Next Generation of Standards Professional Development – Phase 2: Developing Career Path and Career Map.”  It is a great adjunct to other educational efforts like the ANSI Standards Simulation Competition that I participated in last week!
