1.1这些试验方法包括使用两种烘箱干燥程序和一种卡尔费休程序测定纤维素中的水分。 1.2测试程序按以下顺序出现: 小节 试验方法A — 样品在烘箱中称重 4-10 试验方法B — 在烘箱外称重样本 11-17 试验方法C — 卡尔费休法 18-25 1.3以国际单位制表示的数值应视为标准。括号中给出的值仅供参考。 1.4 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和健康实践，并确定监管限制的适用性。 ====意义和用途====== 这些测试方法确定了纤维素样品中包含的水分量，该水分量确定了样品中存在的骨干纤维素量。 当使用纤维素作为生产纤维素衍生物的起始材料时，样品中纤维素的实际量是一个基本实体。

1.1 These test methods cover the determination of moisture in cellulose using two oven-drying procedures and one Karl Fischer procedure. 1.2 The test procedures appear in the following order: Sections Test Method A — Specimen Weighed in Oven 4-10 Test Method B — Specimen Weighed Outside of Oven 11-17 Test Method C — Karl Fischer Method 18-25 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 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 and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== These test methods determine the amount of moisture contained in a cellulose sample which determines the amount of bone dry cellulose present in a sample. The actual amount of cellulose in a sample is an essential entity when using cellulose as a starting material for the production of cellulose derivatives.
