Specifies requirements for round, square and rectangular seamless copper and copper alloy tubes for general engineering purposes. Chemical composition, mechanical and other properties, and manufacturing tolerances are specified.

This Standard specifies requirements for round, square and rectangular seamless copper and copper alloy tubes for general purposes. It does not apply to tubes for heat exchangers (see AS 1569) or tubes for airconditioning (see AS/NZS 1571).NOTE: Advice and recommendations on information to be supplied by the purchaser at the time of enquiry or order are contained in the purchasing guidelines set out in Appendix A.
