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.
© Section 4, Quenched and tempered wire.
(d) Section 5, Strand.
(e) Section 6, Hot-rolled bars with or without subsequent processing.
NOTES:
1 Anchorage devices are covered by AS/NZS 1314.
2 Advice and recommendations on information to be supplied by the purchaser at the time of
enquiry and order are contained in the purchasing guidelines set out in Appendix A.
