Organization: ASTM International
Publication Date: 1 April 2018
Status: active
Page Count: 3
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.

scope:

1.1 These test methods measure the specific gravity of polyols. Test Method A measures the specific gravity of polyols using a pycnometer and Test Method B lists a reference for measuring the specific gravity of liquids using a density meter that is applicable to 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

Note 1: There is no known ISO equivalent to this standard.

1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
