ASTM A751-07a

This document is not anASTM standard and is intended only to provide the user of anASTM 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.
Designation:A751–07 Designation:A751–07a
Standard Test Methods, Practices, and Terminology for
1
Chemical Analysis of Steel Products
This standard is issued under the fixed designation A 751; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
INTRODUCTION
These test methods, practices, and terminology were prepared to answer the need for a single
document that would include all aspects of obtaining and reporting the chemical analysis of steel,
stainless steel, and related alloys. Such subjects as definitions of terms and product (check) analysis
variations(tolerances)requiredclarification.Requirementsforsampling,meetingspecifiedlimits,and
treatment of data usually were not clearly established in product specifications.
It is intended that these test methods, practices, and terminology will contain all requirements for
the determination of chemical composition of steel, stainless steel, or related alloys so that product
specifications will need contain only special modifications and exceptions.
1. Scope*
1.1 These test methods, practices, and terminology cover definitions, reference methods, practices, and guides relating to the
chemical analysis of steel, stainless steel, and related alloys. It includes both wet chemical and instrumental techniques.
1.2 Directions are provided for handling chemical requirements, product analyses, residual elements, and reference standards,
and for the treatment and reporting of chemical analysis data.
1.3 These test methods, practices, and terminology apply only to those product standards which include these test methods,
practices, and terminology, or parts thereof, as a requirement.
1.4 Incasesofconflict,theproductspecificationrequirementsshalltakeprecedenceovertherequirementsofthesetestmethods,
practices, and terminology.
1.5 Attention is directed to ISO/IEC 17025 when there may be a need for information on criteria for evaluation of testing
laboratories.
1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility
of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory
limitations prior to use.
