AASHTO T 244-20

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

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

• Bar Products - Annex A
• Tubular Products - Annex B
• Fasteners - Annex C
• Round Wire Products - Annex D
• Significance of Notched-Bar Impact Testing - Annex E
• Converting Percentage Elongation of Round Specimens to Equivalents for Flat Specimens - Annex F
• Testing Multiwire Strand - 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
• Mechanical Pull Testing of Wire and Welded Wire - Annex K

Attention is directed to AASHTO R 18 when there may be a need for information on criteria for evaluation of testing laboratories.
