Standard Specification for Seamless Copper Pipe, Standard Sizes
ABSTRACT
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.
SIGNIFICANCE AND USE
For purposes of determining compliance with the specified limits for requirements of the properties listed in the following table, an observed value or a calculated value shall be rounded as indicated in accordance with the rounding method of Practice E29.
SCOPE
1.1 This specification establishes the requirements for seamless copper pipe in all nominal or standard pipe sizes, both regular and extra-strong, suitable for use in plumbing, boiler feed lines, and for similar purposes.
1.2 Units—The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are mathematical conversions to SI units, which are provided for information only and are not considered standard.
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
