2021-01-29
Protective clothing is the body protective equipment worn by all kinds of personnel to defend against physical, chemical and biological and other external factors. The specific protective clothing products associated with this outbreak are chemical protective clothing with biological media protective properties.
Protective clothing is the body protective equipment worn by all kinds of personnel to defend against physical, chemical and biological and other external factors. The specific protective clothing products associated with this outbreak are chemical protective clothing with biological media protective properties.
China's chemical protective clothing standards must comply with GB 24539 and GB 29511 standards, and EU chemical protective clothing with biological media protective properties must comply with EN14126 and its referenced EN14325, EN14605 (overall performance of clothing), ISO 13982 (overall performance of clothing) and other standards. For example, products that comply with EN 14605 Type 3 and meet EN 14126 are Type 3B.
The comparison of standards is shown in Table 1 and Table 2.
