The method specified in this International Standard measures the basic constituents in polyols that are soluble in glacial acetic acid and reactive with perchloric acid. Samples containing 0,3 % to 10 % of nitrogen have been evaluated by this method. The method is applicable to amine-based polyols, polyether polyols and polyether polyol blends that are used in polyurethane reactions. The results are measures of batch-to-batch uniformity and may be used to estimate reactivity in polyurethane reactions.<\/p>\n
It is also permissible to express the results in equivalents of base per gram of sample.<\/p>\n
\nNOTE This method is technically equivalent to that in ASTM D 6979.<\/p>\n<\/blockquote>\n
