(Specification)Standard Specification for Seamless Copper Tube in Coils
Standard Specification for Seamless Copper Tube in Coils
ABSTRACT
This standard specification establishes the requirements for seamless copper tube coils, suitable for use in refrigeration and air conditioning or other uses, such as oil lines and gasoline lines. The material of manufacture shall be cast billet, bar, tube and so forth of Copper Alloys No. C10200, C10300, C10800, C12000, or C12200. The tube shall be manufactured by such hot and cold working processes needed to produce a homogeneous, uniform wrought structure. The tube shall be cold drawn to the prescribed finish size and wall thickness. When the cold-drawn temper is required, the final drawing operation shall conform to the specified temper properties. When the annealed temper is required, the tube shall be annealed after the final cold draw to the specified temper properties. The product shall conform to the prescribed electrical mass resistivity, tensile strength, yield strength, Rockwell hardness, and expansion. Each tube shall be subjected to an eddy-current test. Particular coppers shall be tested to meet the cuprous oxide, embrittlement, and cleanness requirements.
SCOPE
1.1 This specification establishes the requirements for seamless copper tube in coils, suitable for use in refrigeration and air conditioning or other uses, such as oil lines and gasoline lines.
1.2 UnitsThe values stated in inch-pound units are 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 The tube shall be produced of the following coppers. Unless otherwise specified, tubes made from any one of these coppers may be supplied:
The following safety hazards caveat pertains to the test method portion, Section 17, 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.
