    Significance and Use

    4.1 This practice, used in conjunction with the following quantitative atomic emission spectrochemical test method, B954, is suitable for use in manufacturing control, material or product acceptance, certification, and research and development.

    1. Scope

    1.1 This practice describes the sampling of magnesium and magnesium-base alloys to obtain a chill-cast sample suitable for quantitative atomic emission spectrochemical analysis. The disk in the region to be excited is representative of the melt and gives a repeatability of results that approach that of the reference materials used.

    1.2 This practice describes the procedure for representative sampling of molten metal.

    1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

    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. Specific precautionary statements are given in 5.1.
