(Specification)Standard Specification for Test Coupons for Steel Castings
Standard Specification for Test Coupons for Steel Castings
ABSTRACT
This specification defines the geometries of several separately-cast and integrally-cast test coupons for use as specified in the applicable casting product or common requirements standard. Procedures for molding, casting, heat treating, machining, or testing are not covered in the standard, and are instead addressed as needed and appropriate by the applicable product or common requirements standard. The applicable casting product standard or common requirements standard or both provide information regarding the number of coupons, molding materials to be used, heat treatment concerns, and other processing issues. The primary function of the test coupon is to provide sound specimens usable for the determination of mechanical, physical, corrosion, or other properties of the metal used to produce the castings. If the test results conform to the stated requirements, then the test coupon may be considered to have functioned acceptably.
SCOPE
1.1 This standard defines the geometries of several separately-cast and integrally-cast test coupons for use as specified in the applicable casting product or common requirements standard. This standard does not address procedures for molding, casting, heat treating, machining, or testing; these items are addressed as needed and appropriate by the applicable product or common requirements standard.
Note 1—The test coupons described herein were formerly defined in multiple casting specifications. Those standards now reference this document when test coupons are required and should be consulted for applicable manufacturing and processing requirements.
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the 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.
