1.1These test methods (A and B) determine the viscosity of polyols in the range from 10 to 100 000 mPa·s(cP) at 25°C. Test Method A is a rotational procedure for determining dynamic viscosity. Test Method B is a general procedure for kinematic viscosity of transparent polyols. (See Note 1.)
1.2The values stated in SI units are to be regarded as the standard. Other equivalent units are provided because of current common usage.
1.3This 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:Test Method A is equivalent to ISO 3219. Test Method B is equivalent to ISO 3104.
1.4This 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.
