标准摘要
[中文适用范围]: 本文件规定了用于生产聚氨酯的芳香族异氰酸酯中总氯含量的测定方法。 总氯含量与水解氯含量(见ISO 15028)之间的差值是产品中残留工艺溶剂的度量。 所有测试方法均适用于各种有机化合物,包括脂肪族异氰酸酯,但可能需要调整样品用量。 这些测试方法可用于研究或质量控制。 [外文原描述]: 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. 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. These test methods can be used for research or for quality control.
