Anti-static work clothes standard Anti-static work clothes national standard EU standard EN1149
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 The standard for electrostatic clothing GB12014-2009 is applicable to 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.
3. Domestic standard antistatic performance mainly tests point-to-point resistance.
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 for the electrostatic performance of protective clothing. A set of standards for 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 resistance over short distances and is not suitable for evaluating the entire garment; BS EN 1149-2 is a standard for methods of testing material resistance ( Loop resistance); BS EN 1149-3 is the standard for testing charge attenuation methods; BS EN 1149-5 specifies the performance and design requirements of antistatic materials for protective clothing.
3. The BS EN 1149 standard has more test items than domestic standards.
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.
