These test methods cover procedures and definitions for the mechanical testing of steel, 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.

The following mechanical tests are described:

• Tension
• Bend
• Hardness
  • Brinell
  • Rockwell
  • Portable
• Impact
• Izod Impact

Annexes covering details peculiar to certain products are appended to these test methods as follows:

• Steel Bar Products - Annex A
• Steel Tubular Products - Annex B
• Steel Fasteners - Annex C
• Round Wire Products - Annex D
• Notes on Significance of Notched-Bar Impact Testing - Annex E
• Procedure for Converting Percentage Elongation of a Standard Round Tension Test Specimen to Equivalent Percentage Elongation of a Standard Flat Specimen - Annex F
• Method of Testing Multiwire Strand for Prestressed Concrete - Annex G
• Rounding of Test Data - Annex H
• Methods for Testing Steel Reinforcing Bars - Annex I
• Procedure for Use and Control of Heat-Cycle Simulation - Annex J
• Method for Mechanical Pull Testing of Wire and Welded Wire Reinforcement for Concrete Pipe and Precast Products - Annex K
