Significance and Use
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.
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.
1.1 These test methods cover the testing of hydroxyethylcellulose.
1.2 The test procedures appear in the following order:
