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 test procedures appear in the following sections:

Sections Acetyl Propionyl or Butyryl Contents 28 to 37 Acetyl Content, Apparent 18 to 27 Acidity Free 12 to 17 Ash 7 to 10 Color and Haze 77 to 81 Heat Stability 57 to 65 Hydroxyl Content 38 to 44 Hydroxyl Content, Primary 46 to 50 Intrinsic Viscosity 67 to 71 Moisture Content 5 to 6 Sulfur or Sulfate Content 51 to 56 Viscosity 74 to 75 Limiting Viscosity Number 67 to 71

1.3 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.
