Bright Annealed Seamless Copper Tube, Standard Specification by ASTM International

This standard outlines bright annealed seamless copper tubing, ideal for refrigeration, oil, and gasoline lines, requiring an interior surface free of scale and dirt. Manufacture involves copper UNS No. C10200, C10300, C10800, C12000, or C12200, processed into uniform, wrought structures. The material adheres to specified chemical compositions, and is supplied in O50 or O60 annealed tempers. Upon testing, the tube meets minimum tensile strength and elongation values, and its diameter can be expanded to the specified size. It can also be flattened as per the described method. Copper UNS nos. C10200, C12000, and C12200 pass the embrittlement test, and tubes not triggering the testing unit's signaling device are considered compliant.
