scope:
1.1 These test methods cover procedures for the testing of cellulose acetate propionates and acetate butyrates. These esters may vary widely in composition and properties, so certain of the procedures can be used only in the ranges of composition where they are suitable.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3 The test procedures appear in the following sections:
| Sections | |
| Acetyl Propionyl or Butyryl Contents | 28-37 |
| Acetyl Content, Apparent | 18-27 |
| Acidity, Free | 12-17 |
| Ash | 7-10 |
| Color and Haze | 77-81 |
| Heat Stability | 57-65 |
| Hydroxyl Content | 38-44 |
| Hydroxyl Content, Primary | 46-50 |
| Intrinsic Viscosity | 67-71 |
| Moisture Content | 5-6 |
| Sulfur or Sulfate Content | 51-56 |
| Viscosity | 74-75 |
| Limiting Viscosity Number | 67-71 |
1.4 This standard does not purport to address 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.
