AS/NZS 4672.1:2007 Steel prestressing materials - Part 1: General requirements
AS 1313-1989, AS 1311-1987
This Standard provides a single specification for material requirements for as-drawn wire, stress-relieved wire, quenched and tempered wire, strand, and hot-rolled steel bars, intended for use in prestressed concrete structures which have been designed in accordance with AS 3600, Concrete structures or NZS 3101.1, Concrete structures Standard, Part 1: The design of concrete structures.
This Standard specifies requirements for high tensile strength steel tendons to be used for prestressing concrete and for other similar purposes (e.g., masonry structures). It applies only to tendons in the condition as supplied by the manufacturer. It does not cover requirements for anchorage devices (see Note 1) and materials used in conjunction with the prestressing steel in structural components.
The specific properties for each type of prestressing steel are given in Sections 2 to 6, namely:
(a) Section 2, As-drawn (mill coil) wire.
(b) Section 3, Stress-relieved wire.
(c) Section 4, Quenched and tempered wire.
(d) Section 5, Strand.
(e) Section 6, Hot-rolled bars with or without subsequent processing.
Note: Standard NZS 3101:Part 1:2006 refers to AS/NZS 4672 Steel prestressing materials (in preparation), AS/NZS 4672.1:2007 and AS/NZS4672.2:2007 are the closest published Standards to this reference.
