A summary of key current activities for ISO TC 197: Hydrogen Technologies is presented as follows:

1. The Draft International Standard 15869.2 Gaseous hydrogen and hydrogen blends – Land vehicle fuel tanks has been sent out for vote and comment by November 1st. A teleconference on comments was held on Oct. 11th. The Committees ISO TC 58/SC 3 (gas cylinders/cylinder design) and ISO TC 22: Road Vehicles are also invited to participate. The U.S. TAG also met by teleconference Oct. 11 to discuss written comments sent in by U.S. TAG members. A revised list of proposed comments has been circulated to U.S. TAG members for their consideration. Shortly following the call, one U.S. TAG member proposed additional comments. Any objections to these comments are requested no later than Oct. 20. U.S. TAG votes are due via e-mail to Debbie Angerman or using the U.S. TAG website by Oct. 29.

2. PDTS 16111.2 Transportable gas storage devices – Hydrogen absorbed in reversible metal hydrides has been sent out for comment and vote. The U.S. has voted in favor with both TC 197 and TC 58/SC 3 voting in the affirmative. The DTS was approved. A meeting to review comments was held on September 6 & 7 in Washington. Informal meeting notes are posted on the U.S. TAG website and were provided by Bob Mauro. Based on editorial and technical clarification comments, the DTS was revised and has been sent to ISO TC 197 for publication as a Technical Specification. Work continues on the International Standard.
   
   
3. DTS 14687-2, Hydrogen fuel – Product specification – Part 2: Proton exchange membrane (PEM) fuel cell applications for road vehicles is out for vote and comment until the end of November.
   
   
4. ISO 14687:1999, Corrigendum 2, Hydrogen fuel – Product specification is out for review and comment until the end of November 2006.
   
   
5. Systematic review of ISO 14687: 1999, Corrigendum 1: 2001, Hydrogen fuel – Product specification is out for review until February 2007.
   
   
6. IEC/CDV 62282-6-2 Fuel cell technologies Part 6-2: Micro fuel cell power systems – Performance is out for review by TC 197 on its hydrogen safety aspects until mid-December 2006.
   
   
7. IEC/CDV 62282-3-3 Fuel cell technologies – Part 3-3: Stationary Fuel cell power systems – Installation is out for review by TC 197 on its hydrogen safety aspects until mid-December 2006.
   
   
8. The U.S. was asked to provide comments on ISO/CD 16110-2, Hydrogen generators using fuel processing technologies—Part 2: Test methods for performance by the first part of October 2006. These are being assessed.
   
   
9. ISO TC 197/WG 13 (hydrogen-specific detectors) will meet in Vancouver, B.C. on October 31 – November 1, 2006.
   
   
10. ISO TC 197/WG 12 (hydrogen fuel quality) will be meeting on Nov 9 & 10 in Honolulu, and Fuel Cell Test QA will meet on November 13, 2006 in conjunction with the Fuel Cell Seminar (Nov 13-17).
