Anotace textu normy ASTM B491/B491M-23 :
This specification covers aluminum and aluminum-alloy extruded round tubes either in coils or straight lengths, for general purpose applications such as refrigeration service, gas lines, oil lines, and instrument lines, in the alloys and tempers. Chemical composition: silicon, iron, copper, manganese, magnesium, chromium, zinc, vanadium, titanium, and aluminum. Tubes produced shall be cooled from an elevated temperature shaping process and naturally aged to a substantially stable condition. The specimen shall then undergo tests to check leakage and any evidence of leak shall be a cause for rejection. The ends of tubes in selected tempers shall be capable of being expanded by forcing a steel pin into the tube without signs of cracks, ruptures, or other defects clearly visible by normal vision. The tubes shall be supplied in the mill finish and shall be uniform as defined by the requirements of this specification and shall be commercially sound. Each tube shall be examined to determine conformance to this specification with respect to general quality and identification marking.
