ISO/TC 197 is developing International Standards and Technical Reports covering a range of hydrogen energy technologies. The following draft documents are available for review. If you have an interest in reviewing one or more of these, please let me know in advance of the cut-off date shown. 

• ISO/DIS 22734-2: Hydrogen generators using water electrolysis process — Part 2: Residential applications has been circulated as a Draft International Standard (DIS). Comments from P-member countries are due to ISO/TC 197 on April 5. Comments are requested to me as soon as possible for preparation of a consensus position.
• A revised draft ISO 17268 Gaseous hydrogen land vehicle refuelling connection devices – has been circulated for comment. This second edition cancels and replaces the first edition, which has been technically revised. Comments requested to me by April 30.

In addition, there are two documents available for systematic review. This means we are trying to evaluate whether the published document should be reaffirmed, undergo revision, or be withdrawn. If you have a view on this, please let me know.

• ISO 13985:2006 Liquid hydrogen – Land vehicle fuel tanks has been circulated for systematic review. Comments are requested to me as soon as possible for preparation of a consensus position.
• ISO 16110-1:2007 Hydrogen generators using fuel processing technologies – Part 1: Safety is out for systematic review. Comments are requested by May 15 for preparation of a consensus position.

And finally, there are two activity updates:

• New work item proposal (NWIP) Gaseous Hydrogen — Cylinders and tubes for stationary storage has been approved. This new work (ISO WI 15399) is allocated to a new ISO/TC 197 working group: ISO/TC 197 WG 15 under the convenership of Mr. Frederic Barth of France.

• Comments received on the committee draft ISO/CD 20100 Gaseous hydrogen — Fuelling stations have been circulated. Nineteen pages of comments were received from the P-members of ISO/TC 197 and ISO/TC 22/SC 25. These comments were forwarded to ISO/TC 197 WG 11 for its consideration in preparation of the Draft International Standard (DIS). WG11 will be meeting in Paris on February 24 and 25, 2010.
