Standard Specification for Sampling Procedure for Impact Testing of Structural Steel
ABSTRACT
This test method deals with the standard sampling procedure for impact testing of structural steel. Covered are the procedures for longitudinal Charpy V-notch testing, which contain two testing frequencies. The two frequencies for testing (H and P), frequency (H) heat testing, and frequency (P) piece testing, are discussed and presented in details.
SCOPE
1.1 This specification covers the procedure for Charpy V-notch testing of structural steel and contains two frequencies of testing. The impact properties of steel can vary within the same heat and piece, be it as-rolled, control-rolled, or heat treated. 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. Normalizing or quenching and tempering the product will reduce the degree of variation.
1.2 This specification is intended to supplement specifications for structural steel when so specified.
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.
1.4 Two frequencies of testing (P and H) are prescribed.
1.5 The values stated in either inch-pound units or SI units are to be regarded as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining values from the two systems may result in nonconformance with this specification.
1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
