ASTM D871-96(2004) - 1.6.2004

Significance and Use

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:

Combined Acetyl or Acetic Acid Content

	Sections
Ash	to
Color and Haze	to

Test Method A. Solution Method	, to
Test Method B. Heterogeneous Saponification Method	, to
Free Acidity	to
Heat Stability	to
Hydroxyl Content	to
Intrinsic Viscosity	to
Moisture Content	to
Primary Hydroxyl Content	to
Sulfur or Sulfate Content	to
Viscosity	to

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

1.4 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.
