About Amendment 4 to AS/NZS 5601.1

Amendment 4 to AS/NZS 5601.1 relates to the use of new quick connect devices for LP Gas cylinders (LCC27) which will apply from 1 October 2021. for leisure cylinders (nominally 10kg or less).

The new valve incorporates a back check valve to prevent gas flow unless the gas connection is made. The new valve and connection are aimed at reducing the risk of gas leakage and gas safety incidences to improve consumer safety.

Transition period

There is a 12 month transition timeframe (from the date of publication) for the LP gas cylinder industry to prepare. Refer to the timeline diagram below.

From 1 October 2021, gasfitting work for leisure cylinders (nominally 10kg or less) will allow for the use of the new cylinder quick connect device (LCC27) or the current Type 21 POL connection.

About revision of AS/NZS 5601.2

AS/NZS 5601.2: 2020 introduces new requirements for LP gas cylinders connections (similar to those contained in Amendment 4 above), and improved safety requirements for caravans and boats.

A six month transition period (from date of publication) for AS/NZS 5601.2 will apply, except for requirements relating to the cylinder quick connect device for LP cylinders (LCC27), where a 12 month transition applies from the date of publication.

As above from 1 October 2021 both the new LCC27 device and current Type 21 connection can be used.

Some of the key changes affecting caravans and boats include:

      • Prohibiting the installation of in-situ LP cylinders in caravans,
      • New requirements of a “controlled area” on caravan drawbars to provide clarity with respect to clearances between cylinders and electrical equipment including road safety equipment
      • Electrical shut off devices in cylinder compartments needing to be encapsulated, and
      • New greater overhead clearances from rangehoods to cookers to align with international best practice.
