(Test Method)Standard Test Methods for Hydroxypropylcellulose
Standard Test Methods for Hydroxypropylcellulose
SIGNIFICANCE AND USE
5.1 The results of this test are used for calculating the total solids in the sample; and, by common usage, all materials volatile at this test temperature are designated as moisture.
5.2 Moisture analysis (along with residue on ignition) is a measure of the amount of active polymer in the material and must be considered when determining the amount of hydroxypropylcellulose to use in various formulations.
SCOPE
1.1 These test methods cover the testing of hydroxypropylcellulose.
1.2 The test procedures appear in the following order:
Sections
Moisture
4 – 9
Viscosity
10 – 16
pH
17 – 21
Residue on Ignition

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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. For specific hazard statements, see 26.6.
1.5 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.
