ASTM D4878-98 - 10.7.1998
 
1. Scope

1.1 These test methods (A and B) determine the viscosities of polyols in the range from 10 to 100000 cP at 25°C or at 50°C. Test Method A also applies to more viscous samples that are soluble in -butyl acetate. (See Note.)

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 problems, 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-There is no equivalent ISO standard.
