ASTM A1067/A1067M-12a
(Specification)Standard Specification for Test Coupons for Steel Castings
Standard Specification for Test Coupons for Steel Castings
SCOPE
1.1 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. 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.

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

limitations prior to use.
2. Ordering Information
2.1 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.
3. Materials and Manufacture
3.1 Unless specified otherwise by the purchaser, test coupons shall be poured from the same heat, or from the same master heat,
or from a sub-heat from the same master heat as the castings they are to represent.
3.2 Except where specified herein or in the applicable product or common requirements standard, the details of the gating and
risering of the coupons are left to the discretion of the producer.
3.3 The test coupons shall be processed and heat-treated as specified in the applicable product or common requirements
specification. Except when specified otherwise, the portion of the test coupon from which the test specimen or specimens are to
be machined may be cut from the riser or feeder prior to heat treatment.
4. Performance Requirements
4.1 The primary function of the test coupon is to provide sound specimens useable 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.
5. Other Requirements
5.1 The casting producer shall establish procedures for the identification and traceability of the coupons from pouring through
testing.
6. Dimensions and Permissible Variations
6.1 The drawings shown in this standard are not necessarily drawn to scale. The values shown in the tables constitute the
dimensional requirements.
6.2 The drawings shown in this standard depict the more commonly used test coupons (Figs. 1-9). Other designs may be suitable
when shown to produce acceptable properties or where agreed.
