1.1 These test methods cover mechanical testsdescribed in ASTM, EN, ISO and JIS standards that utilize the SIsystem of units. The test methods in each system are not exactequivalents. Each standards system (ASTM, EN, ISO and JIS) shall beused independently of the other. Combining requirements from anytwo or more systems may result in nonconformance with the purchaseorder.

1.2 These test methods cover procedures for themechanical testing of steels, stainless steels, and related alloys.The various mechanical tests herein described are used to determineproperties required in the product specifications. Variations intesting methods are to be avoided, and standard methods of testingare to be followed to obtain reproducible and comparable results.In those cases in which the testing requirements for certainproducts are unique or at variance with these general procedures,the product specification testing requirements shall control.

1.3 Only one of the testing procedure tracks shallbe followed: ASTM, EN, ISO or JIS. When a test method or practiceis not available in one of the tracks then an appropriate testmethod or practice from an alternative track shall be used. Therespective tests are listed in the column shown in Table 1.

Note1—The test methods in each system are not exact equivalents.

1.4 The values stated in SI units are to be regardedas standard. No other units of measurement are included in thisstandard.

1.5 Attention is directed to Practice ISO 17025 whenthere may be a need for information on criteria for evaluation oftesting laboratories.

1.6 This standard does notpurport to address all of the safety concerns, if any, associatedwith its use. It is the responsibility of the user of this standardto establish appropriate safety and health practices and determinethe applicability of regulatory limitations prior touse.
