Specifies the durability requirements for steel lintels and shelf angles built into masonry. Appendices includes methods for determining durability classification of coating of lintels, as well as a method for identifying stainless steel grades.

This Standard specifies the requirements and methods of test for durability performance of steel lintels and shelf angles to be built into masonry.NOTES:1 This Standard does not cover requirements for structural design or the method of its determination. Details for these are given by NZS 3404, AS 3700, AS 4100, NZS 4210 or AS/NZS 4600.2 The design and installation requirements for lintels and shelf angles are specified in AS 3700 and NZS 4203.3 Throughout this Standard, lintel signifies lintel or shelf angle, unless stated otherwise.4 Lintels with a high durability classification may be used for less severe corrosion conditions.5 The durability performance categories employed in this Standard are compatible with the environments specified in AS 3700, NZS 3604 and AS/NZS 2312.This Standard applies to lintels and shelf angles used in masonry construction as described in AS 3700 and NZS 4210.
