standard byInternational Organization for Standardization , 04/01/2026
This document specifies the determination of the total chlorine content of aromatic isocyanates used in the preparation of polyurethanes.
u000bThe 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. All the test methods are applicable to a variety of organic compounds, including aliphatic isocyanates, but the amount of sample used might need to be adjusted.
u000bThese test methods can be used for research or for quality control.
