标准编号：ISO 26603:2017
中文名称：塑料 聚氨酯生产中使用的芳香族异氰酸酯 总氯的测定
英文名称：Plastics — Aromatic isocyanates for use in the production of polyurethanes — Determination of total chlorine
发布日期：2017-03
标准范围
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.
