1.1This specification establishes the requirements for welded copper tube with a longitudinal seam free of filler metal produced from sheet or strip of the following coppers:
Copper UNS Nos. | Type of Copper |
C10100 | Oxygen-free electronic |
C10200 | Oxygen-free |
C10300 | Oxygen-free, extra low phosphorus |
C10800 | Oxygen-free, low phosphorus |
C11000 | Electrolytic tough pitch |
C12000 | Phosphorus deoxidized, low residual phosphorus |
C12200 | Phosphorus deoxidized, high residual phosphorus |
C14200 | Phosphorus deoxidized, arsenical |
1.2Unless otherwise specified in the contract or purchase order, product furnished of any listed copper, with the exception of copper C11000, shall be considered acceptable.
1.2.1Copper C11000 welded tube shall not be used in applications where hydrogen embrittlement during heating is a concern.
1.3Units—The values stated in inch-pound units are to be regarded as standard except for grain size, which is given in SI units. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.
1.4The following hazard caveat pertains only to Section 13 of this specification: 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.5This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
