1.1This practice covers the determination of silver corrections for fire assay of metal bearing ores, concentrates, and related metallurgical materials using the spent slags and cupels from the fire assay process, by gravimetry and atomic absorption spectrophotometry.
1.2The test methods appear in the following order:
| Sections | |
| Gravimetric Method | 10–11 |
| Atomic Absorption Method | 12–13 |
1.3Units—The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4This 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 Practices E50 and ISO Guide 35:1989.)
1.5This 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.
