|Publication Date:||10 November 2002|
|ICS Code (Auxiliary materials and additives for plastics):||83.040.30|
|ICS Code (Thermoplastic materials):||83.080.20|
significance And Use:
This test method is suitable for quality control, as a specification test, and for research. It is necessary when converting from kinematic to absolute viscosity.
1.1 This test method measures the specific gravity of polyols using a pycnometer. (See Note 1.)
1.2 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-There is no equivalent ISO standard.
