AS 1571:2020 Copper - Seamless tubes for air-conditioning and refrigeration
Standards Australia
Supersedes: AS/NZS 1571:1995 Copper - Seamless tubes for air-conditioning and refrigeration
Draft Designation: DR AS 1571:2019The objective of this document is to specify requirements for round seamless copper tubes for use in air-conditioning and refrigeration.
The major changes in this edition include —
(a) increase in the range of sizes for 1/2H tubes;
(b) provision that combination of selection of diameter and wall thickness must conform to AS 4041;
(c) limitations on the minimum wall thickness of tubes being flared;
(d) refinement of the method of testing for cleanness; and
(e) addition of the calculation for determining safe working pressure.
The terms "normative" and "informative" are used in Standards to define the application of the appendices to which they apply. A "normative" appendix is an integral part of a Standard, whereas an "informative" appendix is only for information and guidance.
Originated in Australia as part of AS B2-1928. Previous edition Australia AS 1571-1985. Jointly revised and designated as AS/NZS 1571:1995. Revised and redesignated as AS 1571:2020
This document specifies the requirements for round, seamless copper tubes, manufactured from phosphorus-deoxidized copper containing high residual phosphorus and intended for use in air-
conditioning and refrigeration.
