1.1These test methods cover the atomic absorption determination of silver in water. Section 34 on Quality Control pertains to these test methods. Three test methods are given as follows:
| | Concentration
Range |
Sections |
| |
| Test Method A—Atomic Absorption—Chelation-ExtractionA | 1 to 10 μg/L | 7 – 15 |
| Test Method B—Atomic Absorption—Direct | 0.1 to 10 mg/L | 16 – 24 |
| Test Method C—Atomic Absorption—Graphite Furnace | 1 to 25 μg/L | 25 – 33 |
1.2The values stated in SI units are to be regarded as standard. The values given in parentheses are mathematical conversion to inch-pound units that are provided for information only and are not considered standard.
1.3This 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. Specific precautionary statements are given in 11.5, 11.12.1, 13.8, and 22.1.
1.4This 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.
