Описание
Причина отменыFormerly under the jurisdiction of Committee D01 on Paint and Related Coating, Materials, and Applications, this test method was withdrawn in January 2017 in accordance with section 10.6.3 of the Regulations Governing ASTM Technical Committees, which requires that standards shall be updated by the end of the eighth year since the last approval date.Значение и использование

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.

Область применения

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 ASpecimen Weighed in Oven4-10
Test Method BSpecimen Weighed Outside of Oven11-17
Test Method CKarl Fischer Method18-25

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.
