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.
