This Standard was prepared by the Joint Standards Australia/Standards New Zealand Committee BD-011, Interior Board Lining, to supersede AS/NZS 2589:2007, Gypsum linings—Application and finishing.

This Standard incorporates Amendment No. 1 (November 2018) and Amendment No. 2 (April 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 manufacturers, designers and users of gypsum linings with requirements for the application and finishing of such linings in residential and commercial construction applications. This Standard provides a reference for the building industry and specifiers, and a basic Standard for adoption in contracts.

This edition incorporates the following major changes to the previous editions:

(a) Inclusion of surface tolerances.
(b) Cross-reference and alignment to AS/NZS 2311.

Statements expressed in mandatory terms in notes to tables are deemed to be requirements of this Standard.

The terms ‘normative’ and ‘informative’ have been used in this Standard 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.
