Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total chlorine ISO 26603:2008

Publication date:   Aug 11, 2008

Scope

ISO 26603:2008 is used to determine 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.
