Anti-static clothing Anti-static work clothing standards
Anti-static work clothes (referred to as “anti-static clothes”) refer to fabrics sewn with anti-static fabrics in order to prevent the accumulation of static electricity in clothes. Made work clothes. The standards for anti-static clothing include the national standard GB12014-2009 and the European standard EN1149.
1. Domestic anti-static clothing standard GB12014-2009
1. Domestic anti-static clothing standard GB12014-2009 is a newer national standard drafted by the Beijing Labor Protection Research Institute, with participation from Shaanxi Yuanfeng, Xi’an Jingcheng Garment Co., Ltd., and the Soldier Center of the General Logistics Research Institute. It is suitable for anti-static clothing worn in places that may cause electric shock, fire and explosion hazards. It is not suitable for resisting power supply voltage.
2. Anti-static clothing is generally made of ordinary fibers blended with conductive fibers or embedded with conductive filaments. It is usually made of polyester filaments mixed with conductive fibers. production.
2. EU anti-static clothing standard BS EN 1149
1. EU anti-static clothing standard BS EN 1149 is issued by the European Standards Committee and is a test protection Serving a series of standards for electrostatic performance testing methods and requirements.
2. The entire EU electrostatic protective clothing testing method standard is divided into 4 parts. The measurement items are mainly electrostatic properties, and other properties are basically not covered.
BS EN 1149-1 is a test method for most properties of electrostatic dissipation behavior based on surface resistance. It determines the resistance over short distances and does not Suitable for evaluating the entire garment;
BS EN 1149-2 is the standard for testing material resistance methods (loop resistance);
BS EN 1149-3 is the standard for testing charge attenuation methods;
BS EN 1149-5 specifies antistatic materials for protective clothing Performance and design requirements.
3. The BS EN 1149 standard has more test items than the domestic standard, while the domestic standard mainly tests point-to-point resistance, which is relatively simple.
4. Since the anti-static clothing standards mainly focus on the anti-static performance of clothing, there are no requirements for the flame retardant performance of clothing. At present, anti-static clothing at home and abroad Clothing fabrics are mainly made of conductive fibers spun from ordinary fibers or embedded with conductive filaments.
The anti-static work clothes produced by the city’s textile industry can pass many standards such as EN1149-3/EN1149-5/EN1149-1 and the national standard GB12014-2009.
