(Test Method)Standard Test Methods, Practices, and Terminology for Chemical Analysis of Steel Products
Standard Test Methods, Practices, and Terminology for Chemical Analysis of Steel Products
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 In cases of conflict, the product specification requirements shall take precedence over the requirements of these test methods, 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.

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

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.

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
