Protective clothing is a physical protective equipment worn by all kinds of people to protect against physical, chemical, biological and other external factors. The specific protective clothing product related to this epidemic is a chemical protective clothing with protective properties against biological media.
my country's chemical protective clothing standards need to comply with GB 24539 and GB 29511 standards. The EU chemical protective clothing with biological media protection performance needs to comply with EN14126 and its reference EN14325, EN14605 (overall clothing performance), ISO 13982 (overall clothing performance) and other standards. For example, a product that meets the Type 3 standard of EN 14605 and at the same time meets the requirements of EN 14126 is Type 3B.
See Table 1 and Table 2 for the comparison of standards.
