Abstract: The performance of respiratory protective devices is directly related to the life safety of users, so the making and revision of relevant national standards are very important. Based on the performance requirements and test methods of filtering respiratory protective devices for self-rescue from fire, this paper compares and analyzes the similarities and differences between the current national standard GB 21976.1-2008 and the relevant standards of Europe, the United States and the International Organization for Standardization. The research results show that compared with the European and American standards, especially the latest ISO standards, there are gaps in both performance requirements and test methods of the domestic standards, especially the protective performance and test methods of the filter device against toxic gases, and practical performance tests of the respirator. The relevant requirements of the existing national standard are not adequate to the investigation of the comprehensive performance of respiratory protective devices under actual use conditions. It is suggested to refer to the foreign standards and revise GB 21976.1-2008, so as to effectively guarantee the safety of users and standardize the production of related products.

Key words: filtering respiratory protective device for self-rescue from fire, standard of respiratory protective devices, performance index, test method
