AS 4200.1:2017 Pliable building membranes and underlays, Part 1: Materials
Standards Australia
This Standard incorporates Amendment No. 1 (June 2021). The changes required by the
Amendment are indicated in the text by a marginal bar and amendment number against the
clause, note, table, figure or part thereof affected.
The objective of this Standard is to provide a means of testing and evaluating pliable
building membrane materials for various applications within a building structure.
Amendment No. 1 to this document was prepared by the Australian members of Joint
Standards Australia/Standards New Zealand Committee BD-058, Thermal Insulation. As a
consequence of Amendment No. 1, which is published as an Australian-only amendment,
the designation of this document has been changed from AS/NZS 4200.1:2017 to
AS 4200.1:2017.
The objective of this revision is to provide broader material classifications for pliable
building membranes to assist users in making informed decisions on how to select the right
material for the chosen application, including classification of electrical conductivity.
It is acknowledged that further research is required to better define the Duty Classifications
for all material types in common use. When this work is completed the Duty Classifications
will be reviewed and if justified, proposed for revision in a future amendment to this
Standard. This revision also includes optional tests for material properties that determine
long-term durability which will generate market data able to be used within the next
revision.
This Standard is intended to be read in conjunction with AS 4200.2, Pliable building
membranes, Part 2: Installation requirements.
The term ‘normative’ has been used in this Standard to define the application of the
appendix to which it applies. A ‘normative’ appendix is an integral part of a Standard.
First published as part of AS CA22-1965. AS CA22-1965 revised and redesignated AS 1736-1975. AS 1903 first published 1976. AS 1903-1976 and part of AS 1736-1975 jointly revised, amalgamated and redesignated as AS/NZS 4200.1:1994. Second edition 2017. Reissued and redesignated incorporating Amendment No. 1 (June 2021) as AS 4200.1:2017.
This Standard sets out requirements for materials for use as pliable building membranes
(also known as ‘sarking’ or ‘underlay’), when used either independently or as a facing to
other materials, such as insulation materials, for any one or more of the following control
functions:
(a) Water control.
(b) Thermal control.
(c) Vapour control.
(d) Air control.
This Standard does not cover requirements for materials used in the following applications:
(i) Air-handling ducts and building services.
(ii) Under concrete slabs on-ground.
(iii) Waterproofing above flat concrete roofs.
NOTE: Thermal performance of reflective insulation pliable building membranes and faced
building blankets is specified in AS/NZS 4859.1.
