"Standard Test Methods and Definitions for Mechanical Testing of Steel Products" cover procedures and definitions for the mechanical testing of steels, stainless steels, and related alloys. The various mechanical tests herein described are used to determine properties required in the product specifications. Variations in testing methods are to be avoided, and standard methods of testing are to be followed to obtain reproducible and comparable results. | 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. Designation A370 17 Standard Test Methods and Definitions for Mechanical Testing of Steel Products1 This standard is issued under the fixed designation A370 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. This standard has been approved for use by agencies of the . Department of Defense. 1.
