ASTM B68-02

Standard Specification for Seamless Copper Tube, Bright Annealed

ABSTRACT
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. The tube shall be manufactured by such hot- or cold-working processes as to produce a homogeneous uniform wrought structure in the finished product. The tube shall be cold drawn to the finished size and wall thickness and shall be bright annealed to meet the specified temper. The material shall conform to the chemical composition requirements prescribed and the tube shall be furnished in either of two annealed tempers, light annealed or soft annealed. Grain size and mechanical properties such as tensile strength and elongation shall be determined. The material shall be subjected to expansion and flattening tests to evaluate its performance. An electromagnetic or eddy-current test, a nondestructive test, shall be done as well.
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 inch-pound units are the standard except for grain size, which is given in SI units.
1.3 This specification is the companion to SI Specification B 68M; therefore, no SI equivalents are presented in this specification.
1.4 The following hazard statement pertains only to the test method described in Sections 20.5 and 21.2.6 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.
