Abstract

Specifies the minimum frequency of testing necessary to ensure compliance with the requirements of AS 4672.1 for prestressing steel products intended for use in concrete structures designed in accordance with AS 3600 or NZS 3101.1.

Scope

This Standard sets out the minimum rate of testing of wire, strand and bar for prestressing of permanent structures necessary to comply with the requirements of AS/NZS 4672.1.
NOTE: Manufacturing control should apply to all aspects of production from steel melting to the dispatch of the final product.
