Fecha:
2016-02-01 /Historical
Superseeded by:
Significance and Use:

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.

Scope:

1.1 These test methods cover the testing of sodium carboxymethylcellulose.

1.2 The test procedures appear in the following order:

Sections
Moisture4-9
Degree of Etherification:
Test Method AAcid Wash10-17
Test Method BNonaqueous Titration10, 12, 18-23
Viscosity24-30
Purity31-38
Sodium Glycolate39-47
Sodium Chloride48-55
Density56-62

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.
