AS 2699.3:2020 Built-in components for masonry construction, Part 3: Lintels and shelf angles (durability requirements)
Standards Australia
This Standard is the third part of a three-part series on masonry wall ties, connectors and accessories, and lintels and shelf angles. The series comprises the following:
AS 2699.1, Built-in components for masonry construction, Part 1: Wall ties
AS 2699.2, Built-in components for masonry construction, Part 2: Connectors and accessories
AS 2699.3, Built-in components for masonry construction, Part 3: Lintels and shelf angles (durability requirements)
The objective of this Standard is to provide manufacturers of lintels and shelf angles with specifications to achieve durability requirements, and methods for testing corrosion resistance.
Durability requirements for lintels and shelf angles are specified in AS 3700, Masonry structures and AS 4773.1, Masonry in small buildings, Part 1: Design, and AS 4773.2, Masonry in small buildings, Part 2: Construction.
The terms "normative" and "informative" are used in Standards to define the application of the
appendices to which they apply. A "normative" appendix is an integral part of a Standard, whereas an
"informative" appendix is only for information and guidance.
Notes to clauses in this Standard are for information and guidance only and conformance with them is
not a requirement of the Standard.
First published as AS/NZS 2699.3:2000. Second edition 2002. AS/NZS 2699.3:2002 revised and redesignated AS 2699.3:2020.
This Standard specifies requirements for the durability performance of steel lintels and shelf angles to be built into masonry.
This Standard applies to lintels and shelf angles used in masonry construction described in AS 3700,
AS 4773.1 and AS 4773.2.
NOTE 1: AS 2699.1 specifies the durability performance and test procedures for structural performance of wall ties used in masonry construction.
NOTE 2: AS 2699.2 specifies the durability performance and test procedures for structural performance of connectors and accessories used in masonry construction.
NOTE 3: Throughout this Standard, lintel signifies lintel or shelf angle, unless stated otherwise.
NOTE 4: The durability classifications employed in this Standard are compatible with the environments
specified in ISO 9223, AS 4312—2008, AS 3700, AS 4773.1 and AS 4773.2.
NOTE 5: This Standard does not cover requirements for structural design or the method of its determination. Details for these are given by AS 3700, AS 4773.1, AS 4100, and AS/NZS 4600.
NOTE 6: Design and installation requirements for lintels and shelf angles are specified in AS 3700, AS 4773.1 (design) and AS 4773.2 (construction).
