Historical Standard: Standard Test Method for Dilute Solution Viscosity of Ethylene Polymers

ASTM D1601

Scope

1.1 This test method covers the determination of the dilute solution viscosity of ethylene polymers at 135°C. It is applicable to a reasonably wide spectrum of ethylene polymers having densities from 0.910 to 0.970 g/cm2. Directions are given for the determination of relative viscosity (viscosity ratio), inherent viscosity (logarithmic viscosity number), and intrinsic viscosity (limiting viscosity number) (see Appendix X4).

1.2 The values as 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 1—This test method is technically equivalent to ISO 1628-3.

Note 2—Appendix X1-Appendix X3 contain material from the previous version of Test Method D 1601 and are included for information only.
