    Significance and Use

    4.1 Moisture content of the cellulose ester can be used to estimate the dry weight of the cellulose ester. Since cellulose esters are desiccants, their moisture content can vary greatly depending on storage.

    1. Scope

    1.1 These test methods cover procedures for testing cellulose acetate.

    1.2 The test procedures appear in the following sections:




    8 to 11

    Color and Haze

    67 to 72

    Combined Acetyl or Acetic Acid Content


     Test Method A. Solution Method

    17, 19 to 23

     Test Method B. Heterogeneous Saponification Method

    17, 24 to 26

    Free Acidity

    12 to 16

    Heat Stability

    47 to 56

    Hydroxyl Content

    27 to 33

    Intrinsic Viscosity

    57 to 62

    Moisture Content

    4 to 7

    Primary Hydroxyl Content

    34 to 39

    Sulfur or Sulfate Content

    40 to 45


    63 to 66
