Scope

1.1 This practice covers the general considerations for quantitative sample digestion for total metals in water using closed vessel microwave heating technique. This practice is applicable to surface, saline, domestic, and industrial wastewater. 1.2 Because of the differences among various makes and models of satisfactory instruments, no detailed operating instructions can be provided. Instead, the analyst should follow the instructions provided by the manufacturer of the particular instrument. 1.3 This practice can be used with the following ASTM standards, providing the user determines precision and bias based on this digestion practice: Test Method D857, Test Methods D858, Test Methods D1068, Test Methods D1687, Test Methods D1688, Test Methods D1691, Test Methods D1886, Test Method D1976, Practices D3370, Test Methods D3557, Test Methods D3559, Practice D3919, Test Method D4190, Practice D4453, Practice D4691, and Test Method D5673. 1.4 The 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. 1.5 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. For specific hazard statements, see Section 9. 1.6 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.
