1.1 本试验方法涵盖了蒸发和干燥在植物鞣质分析方法中获得的100 mL部分分析溶液的程序，以便在测定样品中的总固体、可溶性固体和非鞣质时获得一致的结果。本试验方法也适用于在植物鞣质分析方法中测定皮粉样品中的水分以及原材料和废材料中的水分。 1.2 以国际单位制表示的数值应视为标准值。本标准不包括其他计量单位。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全、健康和环境实践，并确定监管限制的适用性。 1.4 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 4.1 该试验方法可用于测定分析溶液中的固体残留物。 4.2 由于本试验方法中可能存在未知错误，因此必须严格遵循该程序，以便在实验室内的样本之间和实验室之间的分析中获得可再现的结果。

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. ====== 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.
