ASTM D4902-99(2020)

ASTM D4902-99(2020) is a standard published by ASTM International. Its full title is "Standard Test Method for Evaporation and Drying of Analytical Solutions". This standard covers: SIGNIFICANCE AND USE 4.1 This test method is useful for determining the solid residue in analytical solutions. 4.2 Because of the possibility of unknown errors in this test method, it is essential that the procedure be followed exactly in order to obtain reproducible results, both among specimens within a laboratory and for analyses between laboratories. SCOPE 1.1 This test method covers a procedure for the evaporating and drying of the 100 mL portions of analytical solution obtained in the methods for vegetable tannin analysis, so that consistent results may be obtained for the determination of total solids, soluble solids, and non-tannins in the sample. This test method is also intended for use in determining the moisture in the hide powder samples and the moisture in raw and spent materials in the methods for vegetable tannin analysis. 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. 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.
