2. Common Terminology for Antistatic Workwear
Antistatic workwear is workwear made of antistatic fabric to prevent the accumulation of static electricity.
Antistatic fabrics are fabrics made by weaving conductive fibers or antistatic synthetic fibers, or a mixture of both, into antistatic workwear to prevent static electricity buildup.
Conductive fibers are fibers made wholly or partially of conductive or semi-conductive materials, whether metallic or organic.
Antistatic workwear generally requires careful and tight stitching at the seams. The seam strength should be tested according to GB 3923, and its breaking strength should not be less than 98N. The structural design should generally be lightweight, comfortable, easy to remove, and allow for free movement. Antistatic workwear is available in sizes X, XL, XXL, and XXXL.
Metal accessories are generally not allowed on the clothing. If necessary (buttons, zippers, etc.), they must not be directly exposed when worn. The clothing should be entirely made of antistatic fabric and should not have a lining. When linings (pockets, reinforcing fabric, etc.) are necessary, the exposed area of the lining should be less than 20% of the total exposed area of the inner surface of the antistatic work clothes; if it exceeds 20% (such as for cold-weather clothing or special clothing), the face mask and lining should be detachable.
