    Withdrawn Rationale:

    This specification establishes the requirements for bright annealed seamless copper tube suitable for use in refrigeration, oil lines, gasoline lines, and so forth, where tube with an interior surface essentially free from scale and dirt is required.

    Formerly under the jurisdiction of Committee B05 on Copper and Copper Alloys, this specification was withdrawn in February 2011 and replaced by Specification B68/B68M 11 on Seamless Copper Tube, Bright Annealed.

    1. Scope

    1.1 This specification establishes the requirements for bright annealed seamless copper tube suitable for use in refrigeration, oil lines, gasoline lines, and so forth, where tube with an interior surface essentially free from scale and dirt is required.

    1.1.1 Tubes made from any of the following Copper UNS No. designations shall be supplied, unless otherwise specified in the contract or purchase order:

    Copper UNS No.Type of CopperC10200Oxygen-free without residual deoxidantsC10300Oxygen-free, extra low phosphorusC10800Oxygen-free, low phosphorusC12000Phosphorus deoxidized, low residual phosphorusC12200Phosphorus deoxidized, high residual phosphorus

    1.2 Values stated in SI units are the standard.

    1.3 This specification is the companion to inch-pound Specification B 68.

    The following hazard statement pertains only to the test method described in Sections and 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.
