Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total chlorine
Preview
Summary
This document specifies the determination of the total chlorine content of aromatic isocyanates
used in the preparation of polyurethanes. The difference between the total chlorine content and the
hydrolyzable chlorine content (see ISO 15028) is a measure of the process solvents left in the product.
Both test methods are applicable to a variety of organic compounds, including aliphatic isocyanates, but
the amount of sample used might need to be adjusted. These test methods can be used for research or
for quality control.
NOTE This document is technically equivalent to ASTM D4661–03.
