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.
