Specifies requirements for round, seamless copper tubes, supplied in coils and straight lengths for use in plumbing, gasfitting and drainage applications. The ranges of nominal sizes are DN 6 to DN 200 inclusive for Types A and B, DN 10 to DN 25 inclusive for Type C and DN 32 to DN 150 inclusive for Type D. Details of dimensions and tolerances, chemical composition, temper and form of material, testing and marking are specified. The appendices propose purchasing guidelines, safe working pressure, testing pressure, and hydrostatic test.

This Standard specifies requirements for round seamless copper tubes intended for use in pressure and non-pressure plumbing, gasfitting and drainage applications.NOTES:1 Clause 4 gives classification of tubes covered by this Standard.2 Guidelines to purchasers on information that should be supplied at the time of enquiry or order are detailed in Appendix A.3 Safe working pressure and testing pressure for installed copper tubes are given in Appendix B.
