The objective of this Standard is to provide essential requirements and deemed-to-conform solutions to promote uniform standards of gas installation, and to provide a stand-alone Standard for LP Gas installations in caravans and boats for non-propulsive purposes.

This Standard is based on the general installation requirements of AS/NZS 5601.1.

This Standard is not to be regarded as a design specification or an instruction manual for untrained persons.

This Standard has no legal standing in its own right, but may acquire legal standing in either of the following circumstances:

(a) Where adopted by a Government or other authority having jurisdiction over relevant installations.
(b) Where adopted as part of an installation specification.

Regulatory bodies (Technical Regulators) may adopt this Standard.

Matters of an advisory or explanatory nature are indicated in the following manners:
(i) The word “NOTE” followed by a statement(s).
(ii) By inclusion in an informative appendix.
(iii) By inclusion in examples or caution statements.

Words that are indicated by italics in the body of the text are terms defined in Clause 1.3. This indication of italics does not apply to the text in the Preface, headings or figures. Section 1 contains the definitions of such terms as they apply to this Standard.

This Standard includes a statement that its requirements do not apply retrospectively.

Section 2 of this Standard details the various aspects of a gas installation that contribute to its safety, stating performance criteria for compliance with legislative requirements for safety of gas installations. Sections 3 to 9 provide more detailed information on conformance to the performance criteria.

The means of conformance in Sections 3 to 9 are not the only means of conformance to the performance criteria in Section 2.

Major changes from AS/NZS 5601.2:2013 include the following:

(A) The terms “pipe”, “piping”, “tube” and “tubing” are used throughout this Standard. They are to be considered to have the same meaning.
(B) Where the term “installation” is used, it is deemed to include the appliances, flues, ventilation, piping, components and other ancillary items.
(C) Introduction of definitions for “controlled area”, “domestic caravan”, “encapsulated”, “ignition source”, “non-sparking by nature”, “quick-connect device (cylinder)” and “toughened safety glass”.
(D) Prohibition of in situ fill cylinders on caravans, see Clause 2.4.5 and Clause 3.1.5.1.
(E) Introduction of requirement for orientation of cylinders on caravan drawbars to allow for unobstructed relief of cylinder pressure, see Clause 3.1.4.
(F) Figures showing “controlled area” and clearances on caravan drawbars for ignition sources, see Clause 3.1.8.
(G) A figure showing venting through a drain outlet from a cylinder compartment in a caravan, see Figure 3.3.1(B).
(H) Introduction of the requirement for shut-off solenoid valves to be “encapsulated” in LP Gas cylinder compartments, see Clauses 3.3.1(g) and 3.3.3(i).
(I) Clarification of access to internal cylinder compartments in caravans, see Clause 3.3.4.1.
(J) Allowance of hard drawn copper for use on houseboats on inland waterways on the low pressure side of the gas installation, see Clause 5.1.4.2.
(K) Limitations of hose assembly pigtails to only be class F, see Clause 5.1.4.3.
(L) Prohibition on the use of press-fit connections, see Clause 5.1.4.4(g).
(M) Introduction of requirements for “encapsulated” electrical devices, see Clause 5.3.
(N) Introduction of increased requirements for new installations of distance between cookers and rangehoods, see Clause 6.11.1.
(O) Introduction of requirement of carbon monoxide detectors in boats to conform with referenced internationally recognized Standards, see Clause 7.5.
(P) Additional requirements for thermal protection of combustible surfaces, see Appendix B.
(Q) New pipe sizing tables allowing for more flow capacity, see Appendix C.
(R) Additional requirements for gas leakage tests for appliances with interlocks, see Clause E.3.2(b).
(S) Introduction new appendix on purging, see Appendix L.
(T) The inclusion of references to a cylinder quick-connect device.

The terms “normative” and “informative” have been used in Standards to define the application of the appendix to which they apply. A “normative” appendix is an integral part of a Standard, whereas an “informative” Appendix is only for information and guidance.
