Standard Practice for Sampling Steel and Iron for Determination of Chemical Composition
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 It is intended that this practice include most requirements for sampling steel and iron for analysis. Standard analytical methods that reference this practice need contain only special modifications and exceptions.
4.3 It is assumed that all who use these procedures will be trained samplers capable of performing common sampling operations skillfully and safely. It is expected that only proper sampling equipment will be used.
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.
Requirements for Sampling and Sample Preparation
Selection of a Sample
Preparation of a Sample
Liquid Iron for Steelmaking and Pig Iron Production
Preparation of a Sample for Analysis
Liquid Iron for Cast Iron Production
Sampling and Sample Preparation for the Determination of
Oxygen and Hydrogen
Liquid Steel for Steel Production
Sampling and Sample Preparation for the Determination
Cast Iron Products
Sampling and Sample Preparation
Selection of a Laboratory Sample or a Sample for
Analysis from a Cast Product
Analysis from a Wrought Product
Sampling of Leaded Steel
Sampling Probes for Use with Liquid Iron and Steel
Sampling Probes for Use with Liquid Steel for the
Determination of Hydrogen
1.3 The values stated in SI units are to be 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 and health practices and determine the applicability of regulatory limitations prior to use. For specific statements, see 188.8.131.52, 184.108.40.206, and 12.5.1 as well as Section 5.
