1.1 These test methods cover mechanical tests described in ASTM, EN, ISO, and JIS standards that utilize the SI system of units. The test methods in each system are not exact equivalents. Each standards system (ASTM, EN, ISO, and JIS) shall be used independently of the other. Combining requirements from any two or more systems may result in nonconformance with the purchase order.
1.2 These test methods cover procedures 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. In those cases in which the testing requirements for certain products 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 shall be followed: ASTM, EN, ISO, or JIS. When a test method or practice is not available in one of the tracks then an appropriate test method or practice from an alternative track shall be used. The respective tests are listed in the column shown in Table 1.
Note 1—The test methods in each system are not exact equivalents.
1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.5 Attention is directed to Practice ISO 17025 when there may be a need for information on criteria for evaluation of testing laboratories.
1.6 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.
|Tension||5 to 12||E8/E8M||10002-1||6892||Z 2241|
|Impact||18 to 26||E23||10045-1||148-1||Z 2242|
A These standards are designated EN ISO; this identifies the adoption of ISO standards by EN. “EN ISO” is part of the designation.
