Hi. Thanks for your answer.
We have ASTM D 4662-03 Standard Test Methods for Polyurethane Raw Materials Determination of Acid and Alkalinity Numbers of Polyols, which is about the same thing but was replaced by the one I mentioned above. I just needed it to check if there is some problem with the old one or some major improvement, otherwise I won't really need it. So I was looking for a free version.
Thanks.
