    1. Scope

    1.1 This 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
    C10100Oxygen-free electronic
    C10200Oxygen-free
    C10300Oxygen-free, extra low phosphorus
    C10800Oxygen-free, low phosphorus
    C11000Electrolytic tough pitch
    C12000Phosphorus deoxidized, low residual phosphorus
    C12200Phosphorus deoxidized, high residual phosphorus
    C14200Phosphorus deoxidized, arsenical

    1.2 Unless otherwise specified in the contract or purchase order, product furnished of any listed copper, with the exception of copper C11000, shall be considered acceptable.

    1.2.1 Copper C11000 welded tube shall not be used in applications where hydrogen embrittlement during heating is a concern.

    1.3 UnitsValues 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, which are provided for information only and are not considered standard.

    1.4 The 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 and health practices and determine the applicability of regulatory limitations prior to use.
