ASTM A1067/A1067M-12a(2018)

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 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 nonconformance 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM A1067/A1067M-12a(2018): Standard Specification for Test Coupons for Steel Castings establishes the geometries and design requirements for several types of test coupons used in evaluating steel castings. This international standard, issued by ASTM, provides a unified reference for coupon dimensions and forms that are applicable to a range of casting product standards and common requirements standards in the steel casting industry.

Test coupons play a crucial role in confirming that the steel used in castings meets specific mechanical, physical, and corrosion-resistance properties as required by both purchasers and relevant standards. However, this specification does not address detailed procedures for molding, casting, heat treating, machining, or mechanical testing, as these topics are covered in the associated casting product standards.

Key Topics

• Test Coupon Geometries: The standard defines both separately cast and integrally cast coupons, including several commonly used shapes such as 2-leg, 4-leg, block, and cylindrical designs, enabling broad industry adoption.
• Dimensional Requirements: All coupon dimensions are explicitly specified in both SI and inch-pound units. Drawings provided are not to scale but serve as reference for minimum requirements.
• Manufacturing Flexibility: The standard leaves specific choices about gating, risering, and some design aspects to the manufacturer, unless otherwise outlined in product-specific standards.
• Testing Representation: Emphasis on the requirement that test coupons must be poured from the same heat or master heat as the steel castings they represent, ensuring authenticity of test results.
• Traceability and Identification: Outlines the need for procedures to maintain coupon traceability from pouring through testing where required.
• Safety and Units Compliance: States the responsibility of the user to observe safety and regulatory requirements, and requires units to be used independently without mixing to avoid noncompliance.
• International Alignment: Developed in accordance with World Trade Organization (WTO) principles for international standards, supporting global trade and acceptance.

Applications

• Quality Assurance in Steel Foundries: Steel casting producers use the defined test coupons to verify that cast materials meet agreed-upon standards for tensile strength, impact resistance, and corrosion properties before shipping products to customers.
• Material Qualification and Certification: The test coupons form the basis for qualification of new casting heats or alloys by providing samples for destructive and non-destructive evaluations.
• Process Validation: Foundries and clients employ these standards to validate that production processes consistently yield compliant mechanical properties.
• Regulatory Compliance and Procurement: Purchasers reference ASTM A1067/A1067M in procurement documents to ensure standardization of test samples across suppliers, promoting transparency and comparability.
• International Trade: By adhering to internationally recognized principles, this standard facilitates acceptance of steel castings and their certification in cross-border transactions.

Related Standards

When using ASTM A1067/A1067M-12a(2018), it is common to reference the following related standards and documents to ensure comprehensive compliance and understanding:

• ASTM Steel Casting Product Standards: Product-specific standards specify the number of test coupons, required testing methods, and acceptance criteria.
• ASTM A703/A703M: Covers common requirements for steel castings, including supplementary requirements for coupons and test procedures.
• ISO Standards on Steel Castings: For international conformity assessment and mutual recognition.
• Other ASTM Test Methods (e.g., ASTM A370 for mechanical testing of steel products): For procedures related to specimen preparation and testing from test coupons.

This standardized approach to test coupon geometry and specification supports the steel casting industry's goals of product reliability, regulatory compliance, and global acceptance.
