1.1These 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.

1.2The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.3The test procedures appear in the following sections:
