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.

Sections Requirements for Sampling and Sample Preparation 6 General 6.1 Sample 6.2 Selection of a Sample 6.3 Preparation of a Sample 6.4 Liquid Iron for Steelmaking and Pig Iron Production 7 General 7.1 Spoon Sampling 7.2 Probe Sampling 7.3 Preparation of a Sample for Analysis 7.4 Liquid Iron for Cast Iron Production 8 General 8.1 Spoon Sampling 8.2 Probe Sampling 8.3 Preparation of a Sample for Analysis 8.4 Sampling and Sample Preparation for the Determination of 8.5 Oxygen and Hydrogen Liquid Steel for Steel Production 9 General 9.1 Probe Sampling 9.2 Spoon Sampling 9.3 Preparation of a Sample for Analysis 9.4 Sampling and Sample Preparation for the Determination 9.5 of Oxygen Sampling and Sample Preparation for the Determination 9.6 of Hydrogen Pig Irons 10 General 10.1 Increment Sampling 10.2 Preparation of a Sample for Analysis 10.3 Cast Iron Products 11 General 11.1 Sampling and Sample Preparation 11.2 Sections Steel Products 12 General 12.1 Selection of a Laboratory Sample or a Sample for 12.2 Analysis from a Cast Product Selection of a Laboratory Sample or a Sample for 12.3 Analysis from a Wrought Product Preparation of a Sample for Analysis 12.4 Sampling of Leaded Steel 12.5 Sampling and Sample Preparation for the Determination 12.6 of Oxygen Sampling and Sample Preparation for the Determination 12.7 of Hydrogen Keywords 13 Annexes Sampling Probes for Use with Liquid Iron and Steel Annex A1 Sampling Probes for Use with Liquid Steel for the Annex A2 Determination of Hydrogen

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.
