1.1ÂThese 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.
1.2ÂThe values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
1.3ÂThe 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 |
1.4ÂThis 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.
1.5ÂThis 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.
