Through the comparative analysis of China's national and international standard systems on chemical
protective clothing (CPC), this paper summarizes the differences in classification and minimum
performance requirements between several standard systems. The study provides the most basic
performance assessment factors for all types of CPC. It can also be observed that the standard systems
of European Standards (EN) and the International Organization for Standardization (ISO) have similar
classifications and performance requirements for CPC, while China's standard systems (GB) mainly give
detailed requirements for emergency team CPC as a supplement for previous international standards.
