- Safety of gas appliances – Interim Standard published
- International award for development of gas detector Standards – Dr Chris Simpson
A new Interim Standard NZS 5266(Int):2011 Safety of gas appliances has been published and supersedes NZS 5262 Gas appliance safety. NZS 5266(Int):2011 applies to specialised appliances and appliances produced in small numbers only. The safety of these appliances is assured through their assessment by an approved practitioner.
NZS 5266(Int) sets out the essential safety requirements for all gas appliances in New Zealand that are not subject to a recognised certification regime. It covers small production gas appliances, specialised gas appliances, and appliances for which a recognised certification scheme does not exist. The objective of this Interim Standard is to provide manufacturers, designers, regulatory authorities, testing laboratories, and similar organisations with a set of safety and performance outcome-oriented criteria, which may be used as the basis for approval of gas appliances for sale in New Zealand.
NZS 5266(Int) and NZS/AS 3645(Int) (Essential requirements for gas equipment, planned for publication in August 2011 to cover essential safety for gas appliances produced in volume) are designed to specify the minimum requirements for the safety of gas appliances and fittings that must be certified before being sold in New Zealand.
Standards New Zealand invites comment on NZS 5266(Int) – comments must be received by 22 June 2012 and this Interim Standard will be confirmed, withdrawn, or revised in the light of comments received. A form for comments is provided at the end of the Interim Standard.

Dr Chris Simpson has worked for 34 years – nearly half his life – on helping to develop Standards for gas detection systems, intrinsic safety, and other equipment for hazardous areas. For 20 of those years, he has been a delegate to the IEC subcommittee for gas analysers and, for some of that time, intrinsic safety.
In July 2011, Chris received the IEC 1906 Award for his contribution to the development of IEC gas detector Standards. Created in 2004 by the IEC Executive Committee, the IEC 1906 Award commemorates the IEC's year of foundation and honours its experts around the world, whose work is fundamental to the IEC.
The IEC 1906 Award citation reads:
For his significant contribution during nearly 20 years to the development of IEC gas detector Standards through active participation in meetings and countless hours spent in drafting or revising these Standards.
Thanks to his extensive expert and practical knowledge of gas detectors, he has had a major impact on the quality of the technical content and readability of the Standards.
Chris believes the areas in which he has mainly worked – equipment Standards and guidance Standards – are important as they can link the designer, the manufacturer, the testing authorities and the user of such equipment, and give at least a minimum expectation to all of them as to what may be regarded as 'fair play'.
Chris has had extensive involvement in IEC documents including producing many drafts that have been incorporated into international, regional, and local Standards. He is also chair of joint Standards Australia/Standards New Zealand subcommittees on intrinsic safety and on gas detectors, and serves on the parent Standards Australia/Standards New Zealand Hazardous Area Committee.

The question is not what you gain from standardisation, it’s what you lose without it.
