Designation: A1067/A1067M −12a (Reapproved 2018)
Standard Specification for
Test Coupons for Steel Castings
1
This standard is issued under the fixed designation A1067/A1067M; the number immediately following the designation indicates the
year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last
reapproval. A superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
1. 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 require-
ments 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 appli-
cable product or common requirements standard.
NOTE 1—The test coupons described herein were formerly defined in
multiple casting specifications. Those standards now reference this docu-
ment 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 noncon-
formance 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 appro-
priate safety, health, and environmental practices and deter-
mine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accor-
dance with internationally recognized principles on standard-
ization established in the Decision on Principles for the
Development of International Standards, Guides and Recom-
mendations issued by the World Trade Organization Technical
Barriers to Trade (TBT) Committee.
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 otherwise specified by the purchaser, test cou-
pons 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.
7. Workmanship, Finish, and Appearance
7.1 Care should be taken in the preparation and pouring of
the molds to avoid the creation of inclusions or other anomalies
in the resulting test specimens.

8. Sampling
8.1 Care shall be taken in the production and processing of
the test coupon to ensure that it is representative of the casting
or castings it represents.
9. Number of Tests and Retests
9.1 Sufficient test coupons shall be produced to provide the
needed number of test specimens.
10. Certification
10.1 Certification of the test coupon is not applicable,
except when specified by the casting purchaser.
11. Product Marking
11.1 Marking of test coupons other than as necessary to
provide the identification and traceability described in 6.1 is
not needed, except where specified by the casting purchaser
and agreed by the producer.
