ASTM B369/B369M-24

Annotation of standard text ASTM B369/B369M-24 :

This specification establishes the requirements for threadless, seamless, and deoxidized copper pipes in straight lengths, in all nominal or standard pipe sizes, for piping systems that are assembled with brazed-joint pipe fittings. The pipe shall be produced from coppers with either UNS No. C10300 or C12200. The materials for manufacture shall be cast billets, bars, or tubes of such purity and soundness as to be suitable for processing by hot extrusion or piercing, and subsequent cold working to produce a uniform wrought structure in the finished product. Products shall be produced in the H58 (drawn general purpose) temper. Products shall be sampled and prepared, then tested accordingly to examine their conformance to dimensional (outer and inner diameters, wall thickness, cross-sectional area, theoretical weight, mass, length, and roundness or squareness), mechanical (tensile strength and Rockwell hardness), and chemical composition requirements. Products shall also meet performance requirements under microscopical examination, electromagnetic (eddy-current) test, hydrostatic test, and pneumatic test.
