CONTAINED IN VOL. 08.03, 2016 Describes measuring alkalinity in low-alkalinity (<0.002 meq/g basicity) polyols.

1.1This test method covers measuring alkalinity in low-alkalinity (<0.002 meq/g basicity) polyols. This alkalinity is often expressed as CPR (controlled polymerization rate) of polyether polyols. This test method is not applicable to amine-based polyols.

1.2The values stated in SI units are to be regarded as the standard.

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 and health practices and determine the applicability of regulatory limitations prior to use.

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