AAMI ST90 – QMS for Processing Health Care Products

AAMI ST90 has just been released.  It’s titled Processing of health care products – Quality management systems for processing in health care facilities.  The new 50 page standard was developed by a group that included industry, practitioners (including nursing representatives), academia, government, affiliated organizations, and other interested parties.  It is focused on guidelines for hospitals and other healthcare facilities.  You’ll use it to set up procedures and guidelines supporting quality management systems (QMS) for processing medical devices (sterilization).

The hospital and health care facilities industry is fast adopting processes used by quality professions for many years.  These protocols are helping this industry improve outcomes, with an increased focus on systematic process improvement using a range of quality tools.    The AAMI ST90 is based on ANSI/AAMI/ISO 13485 and follows its format.  However, you can use this document even if you are not implementing the 13485.

The standard is to be used for the sterilization processing of medical devices.  With the knowledge that many adverse effects are in fact caused by human error, creating a QMS for effective and consistent processing during sterilization is a reasonable goal.  So you’ll find information in this standard for setting your objectives, creating a document trail, management responsibilities, resource management, and of course, measurement, analysis, and improvement.

The AAMI ST90 is then arranged to support this.  It begins with the usual scope, referenced documents, and definitions sections.  Next follow sections on QMS, management, resources, product realization, and the measurement, analysis and improvement process.  Four Annexes cover document and record retention, risk management, product QA testing for steam sterilization, and the six major steps in creating a QMS.  A 30-item bibliography completes the text.

Now you’ll want to get a copy of this new standard.  Choose Document Center Inc., an authorized distributor of the AAMI standards.  You can order them on our website at www.document-center.com in paper format or for pdf download.  Here is a direct link to the order page for AAMI ST90 for your convenience.

SAE J2931/7 Released – Plug-In Vehicle Communication Security

SAE J2931/7, Security for Plug-In Electric Vehicle Communications, has just been released.  This is a new addition to the J2931 set of ground vehicle standards focused on plug-in vehicles.  They center on the intersection of data communications, vehicles, and the “smart” energy grid.

The 65-page SAE J2931/7 sets security requirements for digital communication between Plug-in Electric Vehicles (PEV), the Electric Vehicle Supply Equipment (EVSE) and electric grid components.  These include the utility supplier, the Energy Service Interface (ESI), the Advanced Metering Infrastructure (AMI) and/or the Home Area Network (HAN).  (Boy oh boy, more acronyms!)  Communications may be via wire or wireless, and may be point-to-point or internet-enabled.

The standard begins with the usual scope, referenced documents, and definitions sections.  Next, logical architecture and the available interfaces for plug-in electric vehicles are reviewed.  Section 5 provides you with requirements.  These range from basic assumptions to authentication, authorization, privacy, and data integrity.  Attention is given to the various interest areas: vehicle owner, vehicle operator, vehicle maintenance providers, passengers, energy services and providers, and so on.

Section 6 covers Use Cases.  These include such things as charging locations, payments and the like.  Sections 7 and 8 delve into communication issues.  Section 7 is on the network and 8 is for software vulnerabilities.  A brief Section 9 touches on emerging technologies.

There are a lot of interesting developments in the area of electric vehicles.  Standards provide the structural support necessary for developing the new infrastructure requirements for implementing these technologies.  SAE and its membership recognize the benefits of “smart” cars and a “smart” power grid.  Creating the background protocols for effective and secure communication between electric vehicles and the energy grid is essential.  This work is just another example of the developing inter-reliance between industry sectors not seen in the past.

AS 13001 Updated – Supplier Self Release Training

AS 13001 has just been updated.  The new Revision A has a change in the title.  It’s now Delegated Product Release Verification Training Requirements.  You may be more familiar with this as Supplier Self Release verification training.  The new Revision A is available from Document Center Inc. in paper format, for pdf download, and as part of our Standards Online cloud access service.  The revision is a technical update, primarily intended to bring this standard in line with the new Edition of AS 9117.

The AS 13001 is an Aerospace Standard and reflects the industry’s use of a delegated product release verification system.  This is where a supplier is authorized to ship product directly to the end-use customer without oversight by the contracting organization.  It is essential that the duties that might have previously been performed by a company representative be correctly performed by supplier personnel.  Thus, the need for training.

The 8-page standard begins with the usual scope, referenced documents, and terms and definitions sections.  The core of the technical information is found in the requirements section 4.  This provides an overview, delegating organization training requirements, supplier training requirements and records retention.  Appendix A covers the relationship between this and other SAE standards on the topic. Links are provided to pertinent websites for further assistance.

Normally, an updated standard like this would have black lines in the margins to help you spot the technical changes.  However, they are not provided in this new Revision A.  This is because the changes are so extensive.   The previous original release was only 3 pages in length compared to the 8 pages in this revision.  And, as noted, even the title of the standard has been changed…

ISO 11504 for assessing petroleum contaminated soil is updated

ISO 11504 has been updated.  It’s titled Soil quality – Assessment of impact from soil contaminated with petroleum hydrocarbons.  The new 2nd Edition is a technical update and replaces the previous 1st Edition from 2012.  Both editions are available from Document Center Inc. in either paper format or for pdf download.  They can also be provided as part of our enterprise custom collection subscription service.

ISO 11504 is a technical guideline for choosing the percentage and the types of petroleum compounds to look for when analyzing contamination of soils.  This is the type of standard that will be used to determine if there has been soil contamination from the hurricanes in the southern U.S.  Since petroleum hydrocarbons can be hazardous to human health, proper soil analysis is paramount.

Spotting these compounds can be a challenge when soil samples are taken to the lab.  So this standard reviews how to make a number of critical choices for measurement and risk assessment.  The ISO 11504 starts out with the usual scope, referenced documents, and definitions sections.  Section 4 discusses the principles affecting this type of assessment – Time and distance, for example, can degrade the samples.  So there are a number of factors that have to go into planning your testing.

Section 5 is on the relevant fractions and individual compounds.  This is important since petroleum is composed of various components.  And the types and percentage of hydrocarbons in a sample is the critical issue.  Tables and text provide you with the detail needed.

Section 6 specifically addresses petroleum hydrocarbons in soil.  Discussion on the composition and characteristics of crude and processed oils is enhanced by tables with information on the various petroleum mixtures, compounds, and their attributes.  Section 7 then reviews the exposure element that affects hydrocarbons when present in soil.

ISO 11504 Section 8 covers additional issues related to the sampling and investigation.  These issues range from preventing the loss of these volatile compounds in your samples to their proper storage and transportation.  The document is completed by the addition of 3 informative Annexes.  They discuss various physico-chemical properties of petroleum compounds, hazard level information, and an overview of suggested fractionations in various countries.  A 38-item bibliography is also included.

Now to get your copy of this new update.  You’ll use an authorized distributor of the ISO standards like Document Center Inc.  Our catalog, www.document-center.com, can be used for your purchase. Or go directly to the order page for ISO 11504.

AWS D17.1/D17.1M Update – Aerospace Fusion Welding

AWS is the premier standards organization for the development of welding standards.  And the AWS D17.1/D17.1M is one of their most frequently-used publications.  Now there’s a new 2017 Edition available at Document Center Inc.  You can get copies in both paper format and for pdf download.

The standard is titled Specification for Fusion Welding for Aerospace Applications.  It is a standard that was developed by industry to take the place of Department of Defense documents being withdrawn during the 1990’s mil spec reform.  The first edition was issued as AWS D17.1 in 2001, replacing MIL-STD-2219.  The new 2017 revision is the 3rd Edition, making previous editions obsolete.

Fusion welding refers to welding that includes the melting of the materials during the joining process.  It is particularly important to the airspace industry since quality demands are high.  You’ll find information on both welding practices and non-destructive examination tests for welds in this standard.

The AWS D17.1/D17.1M is arranged in the usual fashion, with the scope, referenced documents and definition sections at the beginning.  The standard then covers design, procedure and performance qualification, and fabrication.  Section 7 is on inspection, while Section 8 covers the repair of existing structures.  Section 9 on non-flight hardware completes the main body of the document.  As noted, there are 9 additional Annexes, both normative and information, at the end of the publication.

If you use this standard, you’ll want to know what the changes in the new  edition are.  Here is the list provided by the AWS Committee:

(1) Removed Annex B for effective throat
(2) Added Annex D—Materials in Table 5.4 with cross-referenced UNS numbers to various proprietary trade names.
(3) Added Annex G—Samples of Welding Forms for WPSs, PQRs, and Welder Performance Qualifications by removing the samples from elsewhere in the standard.
(4) Added Annex H—Qualified Positions for Production Welding
(5) Added Annex I—Common Acronyms Used in this Standard for quick user reference.
(6) Added Figures 5.11C and 5.11D to the standard.
(7) Separated Table B.3 into B.3 and B.3M, one for U.S. Customary Units and one for the International System of Units.
(8) Conversion values were updated to meet the requirements of AWS A1.1, Metric Practice Guide for the Welding Industry.

The committee also used the conventions of underlining text and adding lines in the margins to point out all changes from the previous 2010 Edition.
