Scope

Scope: It specifies the terms and definitions, product classification, technical requirements, test methods, marking and instructions for flame-retardant welding protective masks. Applicable to masks that protect workers from welding fumes and provide some protection against open flames, sparks, molten metal, or ozone generated during welding operations. Applicable to masks that add an activated carbon filter layer to disposable face masks (masks) designed to meet the GB2626 standard for "Respiratory Protection - Self-Suction Filter Particulate Respirators". Main technical content: During welding operations, in addition to welding fumes, open flames, sparks, molten metal, and ozone can also pose a hazard to workers' safety and health. Disposable face masks (masks) are suitable for protecting workers against dust, smoke, fumes, and microorganisms in the workplace. On the basis of these products, adding a flame-retardant outer layer and an activated carbon filter layer can enhance the flame-retardant performance and protection against ozone. These types of masks have broad applications in the fields of safe production and occupational health.
