1.1 This guide describes procedures for the validation of chemical and spectrochemical analytical methods of analysis that are used by a metals, ores, and related materials analysis laboratory.
1.2 This guide may be applied to the validation of laboratory developed (in-house) methods, addition of analytes to an existing standard test method, variation or scope expansion of an existing standard method, or the use of new or different laboratory equipment.
1.3 This guide may also be used to validate the implementation of standard test methods used routinely by laboratories of the mining, ore processing, and metals industry.
