1.1 These test methods cover procedures and definitions for the mechanical testing of wrought and cast 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. 1.2 The following mechanical tests are described: Sections Tension 5 to 13 Bend 14 Hardness 15 Brinell 16 Rockwell 17 Portable 18 Impact 19 to 28 Keywords 29 1.3 Annexes covering details peculiar to certain products are appended to these test methods as follows: Annex Bar Products A1.1 Tubular Products Annex A2 Fasteners Annex A3 Round Wire Products Annex A4 Significance of Notched-Bar Impact Testing Annex A5 Converting Percentage Elongation of Round Specimens to Equivalents for Flat Specimens Annex A6 Testing Multi-Wire Strand Annex A7 Rounding of Test Data Annex A8 Methods for Testing Steel Reinforcing Bars Annex A9 Procedure for Use and Control of Heat-Cycle Simulation Annex A10 1.4 The values stated in inch-pound units are to be regarded as the standard. 1.5 When this document is referenced in a metric product specification, the yield and tensile values may be determined in inch-pound (ksi) units then converted into SI (MPa) units. The elongation determined in inch-pound gage lengths of 2 or 8 in. may be reported in SI unit gage lengths of 50 or 200 mm, respectively, as applicable. Conversely, when this document is referenced in an inch-pound product specification, the yield and tensile values may be determined in SI units then converted into inch-pound units. The elongation determined in SI unit gage lengths of 50 or 200 mm may be reported in inch-pound gage lengths of 2 or 8 in., respectively, as applicable. 1.6 Attention is directed to Practices A 880 and E 1595 when there may be a need for information on criteria for evaluation of testing laboratories. 1.7 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.
