Standard Test Method for Polyurethane Raw Materials: Determination of Basicity in Polyols, Expressed as Percent Nitrogen

Importancia y uso:

5.1 This test method is suitable for quality control, as a specification test, and for research. The results are measures of batch-to-batch uniformity and are useful in estimating reactivity.

5.1.1 The percent nitrogen can be used to characterize a polyol or indicate amounts of certain components in a polyol blend.

5.1.2 It is permissible to also express the results in equivalents of base per gram of sample, if desired.
