Description

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 A1
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 Multiwire 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

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