Scope

Moisture analysis (along with purity) is used to calculate the amount of active polymer in the material and must be considered when determining the amount of sodium carboxymethylcellulose to use in various formulations.

1.1 These test methods cover the testing of sodium carboxymethylcellulose.

1.2 The test procedures appear in the following order:

	Sections
Moisture	4-9
Degree of Etherification:
Test Method A—Acid Wash	10-17
Test Method B—Nonaqueous Titration	10, 12, 18-23
Viscosity	24-30
Purity	31-38
Sodium Glycolate	39-47
Sodium Chloride	48-55
Density	56-62

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. For specific hazard statements, see 15.1 and 20.
