3 Terms and Definitions

For the purpose of this Standard, the following terms and definitions apply.

there is no inevitable relationship between them and the actual conditions in the workplace. Therefore, when selecting protective clothing, on the basis of evaluating the wearer's operating conditions and content, combine the involved risk level, and the performance data of the protective clothing provided by the manufacturer to prevent hazards.

4 Ergonomics

Protective clothing shall be designed and produced according to the following requirements:

a) The materials and components of the protective clothing shall ensure that they do not adversely affect the wearer.

b) While meeting the protection requirements, the protection clothing should make the wearer as comfortable as possible.

c) Where the protective clothing comes into contact with the wearer's body, excessive irritations or injuries caused by rough, sharp angles and protruding parts shall be avoided.

d) Considering the influence of external factors and the possible movement and posture of the wearer during work, the design of the protective clothing shall facilitate the correct position of the wearing and ensure that the position is maintained during the intended use. Therefore, appropriate methods should be adopted to adapt the protective clothing to the shape of the wearer, such as:

suitable adjustment structure and suitable size range.

e) Without affecting the design strength and effect, try to reduce the mass of protective clothing.

f) The design of protective clothing should consider forming a comprehensive protective integrity with other series of protective clothing or equipment after wearing. The connection between protective clothing and other protective equipment, such as the connection from sleeves to gloves, trousers to shoes, hood to respirator, should provide the same level of protection.

If the protective clothing permits humid and heat resistance, the humid and heat resistance shall be small. The test method for humid and heat resistance shall be specified in specific standards.

NOTE 1: The manufacturer shall perform the test in accordance with the test methods specified in national standards or international standards.

NOTE 2: Protective clothing cannot be breathable due to protection requirements, and other

6 Dimensioning

Protective clothing shall be dimensioned according to GB/T 13640-1992.
