This test method covers the spectrographic determination of boron in carbon and low-alloy steel for boron in the concentration range from 0.001 to 0.01 %.

Formerly under the jurisdiction of Committee E01 on Analytical Chemistry for Metals, Ores, and Related Materials, this test method was withdrawn in November 2006.

Область применения

1.1 This test method covers the spectrographic determination of boron in carbon and low-alloy steel for boron in the concentration range from 0.001 to 0.01%.

Note 1--The concentration range of the element listed has been established through cooperative testing of reference materials. The scope is underwritten by available spectrochemical reference materials.

1.2 This test method is applicable for the analysis of carbon and low-alloy steel samples, chill-cast, rolled, or forged, of miscellaneous sizes and shapes on which a flat surface at least 12.7 mm in diameter can be prepared, and which are sufficiently massive to prevent overheating during the discharge. Thin samples less than 3.2 mm but greater than 0.79 mm thick, may be analyzed if these samples are soldered to steel plate having a thickness of at least 3.2 mm.

1.3 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.
