3.1.4 Condition of material: as rolled, stress relieved, nor- malized, normalized and stress relieved, or quenched and tempered. Ordering Information 3.1 The inquiry and order shall indicate the following: 3.1.1 The frequency of testing, (P) or (H). Referenced Documents 2.1 ASTM Standards: A 6/A6M Specification for General Requirements for Rolled Structural Steel Bars, Plates, Shapes, and Sheet Piling 2 A 370 Test Methods and Definitions for Mechanical Testing of Steel Products 3 3. Combining values from the two systems may result in nonconformance with this specification. The values stated in each system are not exact equivalents therefore, each system must be used inde- pendently of the other. Within the text, the SI units are shown in brackets. 1.5 The values stated in either inch-pound units or SI units are to be regarded as standard. 1.4 Two frequencies of testing (P and H) are prescribed. 1.3 This specification does not necessarily apply to all product specifications therefore, the manufacturer or processor should be consulted for energy absorption levels and minimum testing temperatures that can be expected or supplied. 1.2 This specification is intended to supplement specifica- tions for structural steel when so specified. Normalizing or quenching and tempering the product will reduce the degree of variation. The purchaser should, therefore, be aware that testing of one plate, bar, or shape does not provide assurance all plates, bars, or shapes of the same heat as processed will be identical in toughness with the product tested. The impact properties of steel can vary within the same heat and piece, be it as rolled, control rolled, or heat treated. Scope 1.1 This specification establishes the procedure for longitu- dinal Charpy V-notch testing of structural steel and contains two frequencies of testing. This standard has been approved for use by agencies of the Department of Defense. A superscript epsilon ( e ) indicates an editorial change since the last revision or reapproval. A number in parentheses indicates the year of last reapproval. Designation: A 673/A673M – 95 American Association State Highway and Transportation Officials Standard AASHTO No.: T 243 Standard Specification for Sampling Procedure for Impact Testing of Structural Steel 1 This standard is issued under the fixed designation A 673/A673M the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision.
