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 contents are determined by fire assay for the purpose of metallurgical exchange between buyer and seller. 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. |

1. Scope | ||||||||
1.1 This practice covers the silver loss correction, utilizing slag recycling and cupellation of proof silver during the fire assay of metal bearing 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 and health practices and determine
the applicability of regulatory limitations prior to use.
