Standard Test Method for Expansion (Pin Test) of Copper and Copper-Alloy Pipe and Tubing

SIGNIFICANCE AND USE
When properly performed and interpreted, the expansion pin test will provide information with regard to the capacity of a tube for expansion and to reveal surface defects. Expansion pin test may provide data for research and development, engineering design, quality control, and acceptance or rejections in specifications.
SCOPE
1.1 This test method establishes the requirements for the expansion pin test for copper and copper-alloy pipe and tubing in sizes up to and including 4 in. (102 mm) in outside diameter.
Note 1—For tubes of sizes greater than 4 in. in outside diameter, the following flattening test, as described in the various pipe and tube specifications, is recommended as a substitute for the pin expansion test. For pipe and tubes over 4 in. in outside diameter in the annealed condition, a 4-in. long shall be cut from the end of one of the tubes. This 4-in. long sample shall be flattened so that a gage set at three times the wall thickness will pass over the pipe freely throughout the flattened part. The pipe or tube so tested shall develop no cracks or flaws visible to the unaided eye as a result of this test. In making the flattening test, the elements shall be slowly flattened by one stroke of the press.
Note 2—The term "unaided eye," as used herein, permits the use of corrective lenses necessary to obtain normal vision.
1.2 UnitsThe values stated in inch-pound units are regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information purposes only and are not considered standard.
1.3 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.
