Details
1.1 This practice covers the determination of fire assay correction for silver, utilizing proof silver, ores, concentrates, and related metallurgical materials.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. (See Test Methods E1335, Practices E50, Guide E882, and ISO?Guide?35:?2017.)
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
Significance and Use:
5.1 This practice is primarily intended to be used for the correction of silver loss in the fire assay process. Silver assays are determined by fire assay for the purpose of metallurgical exchange between seller and buyer.
5.2 It is assumed that all who use this practice will be trained analysts capable of performing skillfully and safely. It is expected that work will be performed in a properly equipped laboratory under appropriate quality control practices such as those described in Guide E882.
