ASTM D4661 Standard Test Methods for Polyurethane Raw Materials, Determination of Total Chlorine in Isocyanates

EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of ASTM D4661 testing. These test methods determine the total chlorine content of aromatic isocyanates used as polyurethane raw materials. The difference between the total chlorine content and the hydrolyzable chlorine content is a measure of the amount of o-dichlorobenzene and other ring-substituted chlorinated products present. Both procedures are applicable to a variety of organic compounds, but the amount of sample used may need to be varied.
