Safer hydrogen storage – international Standard
Summarised from an article by Dr Chris Jubb and Randy Dey in ISO Focus magazine, June 2009.
An international Standard will help pave the way for larger, widespread applications of hydrogen. Transportable gas storage devices – Hydrogen absorbed in reversible metal hydride, ISO 16111:2008, describes the service conditions, design criteria, type tests, and routine tests to ensure the safety of metal hydride assemblies used for the storage of hydrogen.
The hydrogen stored in metal hydride assemblies will be able to travel across international borders – a major benefit for the industry.

DZ 5259 A1 NZS 5259:2004 Gas Measurement Amendment 1
In order to cite NZS 5259:2004 in the revision of the Gas Regulations 1993, Table 3 of NZS 5259 has been amended to conform to the accuracy of conversion requirements given in the current regulation 9. Some changes have been made to the energy conversion section to clarify accuracy requirements, and the competency requirements have been updated. A small number of technical corrections have also been included in this amendment. Two new appendices have been introduced: a new Appendix B which provides guidance for low pressure accuracy of turbine meters calibrated at high pressure and Appendix N to provide guidance for time-stamped data. Public comment on this draft closes on 24 August 2009.
