Abstract:

In order to promote the improvement of chemical protective clothing technology and product quality, scientifically guide the revision of GB 24539—2009 《protective clothing-performance requirements of chemical protective clothing》 for chemical protective clothing, together with the latest development trends of chemical protective clothing standards by International Organization of Standardization(ISO), the differences between the national standard and the ISO standard were analyzed. Meanwhile, in conjunction with the update of the European Standardization Committee in the EN standards of chemical protective clothing, focusing on the technical requirements of the standards and the core test and evaluation methods including chemical permeation performance, wear resistance and flexibility testing of clothing fabrics, the in-depth discussion on the revision direction and hot issues of the future chemical protective clothing standards in China was discussed, providing scientific technical support for the ongoing revision of standard in China.

Key words: chemical protective clothing, national standard, international standard, chemical permeation performance, wear resistance, flexibility
