Historical Standard: ASTM D1795-96(2007)e1 Standard Test Method for Intrinsic Viscosity of Cellulose
SUPERSEDED (see Active link, below)
ASTM D1795
1. Scope
1.1 This test method covers the determination of the intrinsic viscosity of purified celluloses such as bleached wood pulps, cotton linters, and regenerated cellulose. It is applicable to all cellulose samples with an intrinsic viscosity of 15 dl/g or less. Most native (unpurified) celluloses have intrinsic viscosity values too high for measurement by this test method.
Note 1 - The use of cuprammonium hydroxide solution for regular viscosity determination is described in Method T 206 m-55 of the Technical Association of Pulp and Paper Industry on 'Cuprammonium Disperse Viscosity of Pulp,' and Joint Army-Navy Specifications JAN-C-206.
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
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.
