Significance and Use
5. Significance and UseTop
Bottom
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 used to calculate the amount of active polymer in the material and shall be considered when determining the amount of ethylcellulose in various functions.
1. Scope
1.1 These test methods cover the testing of ethylcellulose.
1.2 The test procedures appear in the following order:
| | Sections |
| Moisture | 4 to 6 |
| Sulfated Ash | 7 to 11 |
| Chlorides (as Sodium Chloride) | 12 to 16 |
| Ethoxyl Content | 20 to 24 |
| Viscosity | 25 to 39 |
1.3 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only.
1.4 Warning???Mercury has been designated by EPA and many state agencies as a hazardous material that can cause central nervous system, kidney and liver damage. Mercury, or its vapor, may be hazardous to health and corrosive to materials. Caution should be taken when handling mercury and mercury-containing products. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA???s website (http://www.epa.gov/mercury/faq.htm) for additional information. Users should be aware that selling mercury or mercury-containing products, or both, in your state may be prohibited by state law.
1.5 This standard may involve hazardous materials, operations, and equipment. 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.
