1.1 这些试验方法 3. 测定木材的水溶性。给出了两种方法，如下所示: 1.1.1 方法A-冷水溶解度- 这种方法可以测量木材中的单宁、树胶、糖和色素。 1.1.2 方法B-热水溶解度- 该方法提供了单宁、树胶、糖、色素、， 还有淀粉 在树林里。 1.2 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。 1.3 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====== 2.1 冷水可以去除一部分外来物质，如单宁、树胶、糖和色素。热水可以去除这些 加 淀粉。

1.1 These test methods 3 cover the determination of the water solubility of wood. Two methods are given, as follows: 1.1.1 Method A—Cold-Water Solubility— This method provides a measure of the tannins, gums, sugars, and coloring matter in the wood. 1.1.2 Method B—Hot-Water Solubility— This method provides a measure of the tannins, gums, sugars, coloring matter, and starches in the wood. 1.2 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. 1.3 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 ====== 2.1 Cold water removes a part of such extraneous materials as tannins, gums, sugars, and coloring matters. Hot water removes these plus the starches.
