(Test Method)Standard Test Methods for Hydroxyethylcellulose
Standard Test Methods for Hydroxyethylcellulose
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 sulfated ash) is a measure of the amount of active polymer in the material and must be considered when determining the amount of hydroxyethyl cellulose to use in various formulations.
SCOPE
1.1 These test methods cover the testing of hydroxyethylcellulose.
1.2 The test procedures appear in the following order:
Sections
Moisture
4 – 9
Ash
10 – 17
Viscosity
18 – 23
Density
24 – 30
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.
