Historical Standard: ASTM D1243-95(2000)e1 Standard Test Method for Dilute Solution Viscosity of Vinyl Chloride Polymers
SUPERSEDED (see Active link, below)
ASTM D1243
1. Scope
1.1 This test method covers the determination of the dilute solution viscosity of vinyl chloride polymers in cyclohexanone. The viscosity is expressed in terms of inherent viscosity (logarithmic viscosity number). The test method is limited to those materials that give clear, uniform solutions at the test dilution.
Note 1--Other expressions for viscosity may be used as described in the Appendix, but any change from the test method as specified shall be stated in the report.
1.2 The values stated in SI units are to be regarded as the standard.
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.
Note 2--Although this test method and ISO 1628-2-1998 differ in approach or detail, data obtained by either are technically equivalent.
