Significance and Use
The mechanical properties determined from test bars for sand, permanent mold, and centrifugal castings poured in accordance with this practice represent the properties of the metal going into castings poured from the same heat. These mechanical properties may not be the same as the properties of the corresponding castings because of the solidification effects of varying size, section, and design.
Test bars for continuous castings are taken from the castings and therefore represent the properties of the castings.
1.1 This practice establishes procedures for preparing test coupons and specimens (machined and unmachined) for tension tests of copper alloys for sand, permanent mold, centrifugal and continuous castings.
1.2 The values stated in inch-pound units are the standard. SI values given in parentheses are for information only.
