| Degree of Etherification: |
|
| ?Test Method A—Acid Wash | 10 – 17 |
| ?Test Method B—Nonaqueous Titration | 10, 12, 18 – 23 |
| Viscosity | 24 – 29 |
| Purity | 30 – 37 |
| Sodium Glycolate | 38 – 46 |
| Sodium Chloride | 47 – 54 |

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 15.1 and 20.
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.
Significance and Use:
5.1 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.
