ASTM E2857-22 - Standard Guide for Validating Analytical Methods

1.1 This guide describes procedures for the validation of chemical and spectrochemical analytical test methods 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 The suggested approaches in 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.

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.
