Issue 46 – February 2013

Standards New Zealand recently published NZS/AS 3645.1:2012 Essential requirements for gas equipment Part 1: Essential safety, NZS/AS 3645.2:2012 Essential requirements for gas equipment Part 2: Certification, and NZS 5266(Int):2012 Safety of gas appliances. Energy Safety sponsored these projects.

NZS/AS 3645.1&2 have been published as full Standards with no changes to the technical content from the 2010 Interim Standards.

  • NZS/AS 3645.1:2012 supersedes NZS 5262:2003 and NZS/AS 3645.1(Int):2010.

  • NZS/AS 3645.2:2012 supersedes NZS 5262:2003 and NZS/AS 3645.2(Int):2010.

NZS 5266 has been reissued as an Interim Standard and supersedes NZS 5262:2003 and NZS 5266(Int):2011. It includes a minor change from the 2011 Interim Standard.

NZS/AS 3645 and NZS 5266(Int) are designed to specify minimum requirements for the safety of gas appliances and fittings that must be certified or endorsed prior to being sold in New Zealand. Although the two Standards may differ slightly in wording, the technical requirements for safety are essentially the same.

NZS/AS 3645

NZS/AS 3645 applies to appliances produced in volume. The Standard:

  • provides manufacturers, designers, regulatory authorities, testing laboratories, and similar organisations with a set of safety and performance outcomes-oriented criteria applicable to products for which regulatory approval is required before sale

  • has been divided into two parts to separate the essential safety requirements and certification requirements

  • will ensure gas appliances supplied to the New Zealand market meet essential safety and compliance requirements, while meeting New Zealand's obligations to international trade.

NZS 5266(Int)

NZS 5266(Int) applies to specialised appliances and to appliances that are produced in small numbers only. Safety of these appliances is assured through their assessment by an approved practitioner. The Interim Standard:

  • provides 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 for sale in New Zealand

  • sets out the essential safety requirements for all gas appliances in New Zealand that are not subject to a recognised certification regime

  • will support trans-Tasman and international trade and ensure gas appliances supplied to the New Zealand market meet essential safety and compliance requirements

  • was first issued as an Interim Standard in 2011. After minor changes in 2012, it was reissued for a further period of comment. This revision has added to the list of characteristics to be assessed and affirmed the validity of tests using Australian test gases for natural gas.

→ As there are no approved practitioners yet, Standards New Zealand has published the Interim Standard to allow practitioners to use the Standard and to comment on it by the end of 2013. Standards New Zealand invites comment on NZS 5266(Int) from persons and organisations concerned with this subject. The date for expiry of comment is 20 December 2013 – 1 year after publication at which time (or earlier) this Interim Standard will be confirmed, withdrawn, or revised in the light of comments received. A form for comment is provided at the end of the Interim Standard.
