RFID Standards Progress

I was in Atlanta a few weeks ago week for a couple of standards events.

First, there was a meeting of ANSI MH10.8.  It is a subgroup of the MH10 group whose scope is: "To facilitate freight movement within transportation and distribution systems by providing standards for transport-packages and unit-loads, including their dimensions, definitions, terminology, coding, labeling, and performance criteria; and to represent the United States' interests within the scope of ISO/TC 122".

The MH10.8 subgroup is responsible for "Coding & Labeling of Unit-Loads". This means bar codes for a lot of the work, but there is an increasing amount of RFID in there. The most well-known standard from MH 10.8 is ANSI MH10.8.2 "Data & Application Identifiers" but the group is responsible for many standards, you can see a full list at below. The meeting in Atlanta spent time reviewing the .1, .7, .12 and .13 documents.

  • MH10.8.1:2006 – Shipping Label Standard
  • MH10.8.2:CM – Data & Application identifier standard
  • MH10.8.3:2002 – Syntax for High Capacity ADC Media
  • MH10.8.4:2002 – RFID Tags for Returnable Containers
  • MH10.8.5 – Retired
  • MH10.8.6:2003 – Product Packaging standard
  • MH10.8.7:2005 – Product Marking standard
  • MH10.8.8:2006 – RFID for Parcels, Packages and Flat Mail
  • MH10.8.9 – Product ID using other than optically readable media
  • MH10.8.10 – RFID for Product Packaging
  • MH10.8.11 – Unit loads and transport packages for North American border crossings
  • MH10.8.12 – Component Marking Standard
  • MH10.8.13 – Label Test Procedures for Bar Code and Two-Dimensional (2D) Label
  • MH10.8.14 – Unique Digital Identifier
  • MH10.8.15 – XML Reader Output from ISO/IEC 15434 formatted AIDC Media

The Data Identifiers standards details the various Data Identifiers that you may use in the numbering of a package to better explain the content of the package. The abstract of the standard says: "This standard provides a comprehensive dictionary of MH 10/SC 8 Data Identifiers and GS1 Application Identifiers, provides for the assignment of new Data Identifiers, as required, and provides a document detailing the correlation, or mapping, of Data Identifiers to Application Identifiers, where a correlation exists."

 

The second meeting this week was the US TAG to ISO/IEC JTC 1/SC 31. The US TAG (AIDC 1) is responsible for creating the US positions and responding to ballots that are posted related to the work of SC 31. This means that almost every standard related to AIDC is reviewed by this group and the US opinion is developed and posted to the international community. For the latest work in SC 31 you can visit http://www.understandrfidstandards.com/isoiec-jtc-1sc-31/ . This web site keeps an updated list of all the RFID related work in the committee.

The big items in RF at the moment include a rework of the ISO/IEC 18000-6 standard (air interface standard for 860-960 MHz). This standard was published in late 2010 and is 470 pages long. It includes four different air interface standards and also how to include battery and sensor support for some of the air interfaces. The new standard will divide the original one into sub-parts so that you can get all the information for a single air interface in one standard without the confusion of the others.

Part 63 is the new standard for what was referred to as ISO/IEC 18000-6 Type C (also known as the EPC UHF Gen 2 standard). All of the new sub parts of this document are now in the first stage (CD) ballot. The various parts are:

  • 18000-6: The general information that relates to all the sub parts
  • 18000-61: Type A
  • 18000-62: Type B
  • 18000-63: Type C
  • 18000-64: Type D

Other RFID work that is happening in SC 31 at this time includes a re-write of ISO/IEC 18000-7 (active RFID at 433 MHz).

The US TAG reviews every document created by SC 31 and provides input to the work. The annual TAG meeting allows the members to get together to review the work of the TAG as well as review the procedures of the group. This year starts the planning for 2012 when the US will host the Plenary of SC 31.

 

The final meeting during this week was the AIM RFID Experts Group (REG). This group has identified several work items that they are looking at. The first of these is a methodology to allow the testing of RFID equipment in the healthcare environment. Working with various groups and Universities, the REG is reviewing proposed test procedures for both implantable medical devices (such as pacemakers) and medical devices used in a medical environment.

The second work item is a white paper to describe the best way to implement a numbering system in an RFID tag. The paper will describe the various existing numbering methodologies that exist and recommend ways to get the best system for your project.

ther work items that are just starting include:

  • The use of RFID in explosive environments
  • The use of RFID on material handling equipment

Standards Update – 3 – February 2011

This month there are a series of ISO RFID standards meetings taking place in Sarasota, FL USA.  The third meeting was SC 31/WG 4/SG 3.  This committee is responsible for RFID air interface standards –  ISO/IEC 18000 series standards.

All of the parts of ISO/IEC 18000 have been published, but work items are currently open to revise parts 6 and 7.

ISO/IEC 18000-6 is the air interface standard for 860 – 960 MHz UHF RFID. This standard was revised and published in 2010 with the addition of a Type D and support for sensors and battery assist. The addition of these options to the standard meant that the document had grown to almost 500 pages.  A new work item to break this standard into smaller parts was approved at the end of 2010 and the committee met, for the first time since that approval, to review the work that has been done.

The standard has been broken into five parts:

  • Part 6: Parameters for air interface communications at 860 MHz to 960 MHz General
  • Part 61: Parameters for air interface communications at 860 MHz to 960 MHz Type A
  • Part 62: Parameters for air interface communications at 860 MHz to 960 MHz Type B
  • Part 63: Parameters for air interface communications at 860 MHz to 960 MHz Type C
  • Part 64: Parameters for air interface communications at 860 MHz to 960 MHz Type D

Each of these parts was approved to move to the first stage of balloting – CD ballot. For more details of how the ISO process works see: http://www.understandrfidstandards.com/how-does-iso-work/

ISO/IEC 18000-7 Parameters for active air interface communications at 433 MHz was last published in 2010. This standard has been opened to revise the technology to include multi-channel utilization and more efficient communication techniques needed to address increased market and application needs for higher and more secure data transmissions. This revision will also specify the sensor interface and a universal mechanism to allow for other services to be enabled on the tag.
