1.1 This guide describes procedures for the internal preparation of reference materials for analytical testing of metals, ores, slags, and other materials encountered within the metals and mining industries. 1.2 This guide is applicable to the production of secondary reference materials only (usually for internal use) and does not apply to the production of certified reference materials (CRMs). Materials may include metals, alloys, minerals, geological materials, manufacturing intermediates, and byproducts. Samples may be in a number of physical forms including blocks, disks, rods, wires, chips, granules, and powders. 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.
