1.1 This practice covers the sampling of all grades of steel, both cast and wrought, and all types (grades) of cast irons and blast furnace iron for chemical and spectrochemical determination of composition. This practice is similar to ISO 14284.

1.2 This practice is divided into the following sections.

1.3 The values stated in SI units are regarded as standard. No other units of measurement are included in this standard.

1.4 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific statements, see 6.4.3.5, 9.4.4.3, 12.5.1, and Section 5.

1.5 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.

4.1 This practice covers all aspects of sampling and preparing steel and iron for chemical analysis as defined in Test Methods, Practices, and Definitions A751 and Specification A48/A48M. Such subjects as sampling location and the sampling of lots are defined.

4.2 This practice includes most requirements for sampling steel and iron for analysis. Standard test methods that reference this practice need contain only special modifications and exceptions.

4.3 All who use these procedures should be trained samplers capable of performing common sampling operations skillfully and safely. Only proper sampling equipment should be used.
