|Publication Date:||1 April 2013|
|ICS Code (Auxiliary materials and additives for plastics):||83.040.30|
|ICS Code (Thermoplastic materials):||83.080.20|
significance And Use:
4.1 These test methods are suitable for quality control, specification testing, and research. The specific gravity is necessary when converting kinematic viscosity to absolute viscosity.
1.1 These test methods measure the specific gravity of polyols. (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 known ISO equivalent to this standard.
