GSO ASTM B42:2016 Scope
This specification covers seamless copper pipe in all nominal standard pipe sizes, both regular and extra-strong, suitable for use in plumbing, boiler feed lines, and for similar purposes. The material shall conform to the specified chemical requirements. The pipe shall be produced from one of C10200, C10300, C10800, C12000, and C12200 copper UNS numbers. All pipes shall normally be furnished in the prescribed annealed, light drawn, or hard drawn temper. The pipe shall be made from copper that is free of cuprous oxide, as determined by microscopical examination. The pipe shall be subjected to expansion or flattening, Eddy-current, and hydrostatic tests. Samples for chemical analysis shall be taken in accordance with Practice E255. However, the manufacturer shall have the option of determining conformance by analyzing samples taken at the time the castings are poured or from the semifinished product, subject to the conditions set in the specification.
