This standard applies to flammable, explosive and other places, the operating personnel to eliminate static electricity while wearing the body anti-static and conductive shoes and sneakers. This standard is the reference to ISO 2251 and ISO 2024 formulation
1, wearing a site
1.1 Anti-static anti-static shoes and rubber-soled shoes used by humans to prevent static electricity may cause fire, explosion place (for example, rubber, chemical, printing, medical, electronics and other industries in some places). At the same time, it can also avoid the following 250V electrical equipment caused by accidental electric shock and fire on the human body.
1.2 Conductive shoes and conductive shoes and used to prevent static electricity caused by humans, fire, explosion sites (eg, fire work industry, some of the places). But it only applies to operating personnel will not place electric shock. 1.3 for the maintenance of power equipment or handling high-voltage electrical equipment with electric shock hazard to staff, rubber-soled shoes against wear anti-static, conductive rubber-soled shoes.
2 performance indicators
2.1 Electrical performance
2.1.1 Anti-static shoes and shoe wear in the period, according to GB 4386-84 "anti-static shoes and conductive shoes and resistance measurement method" to measure. Anti-static shoes and soles of the resistance to be 0.5 × 105Ω to 1.0 × 108Ω range.
2.1.2 Conductive shoes and wear the shoes during the press GB 4386-84. Conductive shoes and soles of the resistance value must be less than 1.5 × 10 ^ 5Ω.
2.2 Other performance indicators
2.2.1 Anti-static shoes and conductive shoes and other performance requirements, appropriate footwear must meet national standards and technical requirements.
2.2.2 carry out anti-static rubber-soled shoes, conductive shoes and the structural design and selection of materials must be taken into account so that the resistance of the wear shoe department, under the influence of pollution, the least change.
2.2.3 special requirements on the anti-static rubber-soled shoes, conductive rubber-soled shoes (for example, need to have the acid, alkali, oil properties) should also meet appropriate technical standards.
3 wear requirements
3.1 To ensure the elimination of the effect of the human body static electricity, wear anti-static rubber-soled shoes, in which the resistance of the ground should be no greater than 1.0 × 108Ω; wear conductive rubber-soled shoes, in which the resistance of the ground should be no greater than 1.5 × 105Ω.
3.2 In the process of shoe wear, anti-static shoes and the bottom conductive shoes and not contaminated with impurities in insulation.
3.3 in the shoes of the wear process, taking care to avoid while wearing insulated and strong or thick wool socks and insoles and other insulation.
4 soles of the electrical performance test anti-static rubber-soled shoes, conductive shoes and soles of the resistance value should be provided for the method GB 4386-84, procedures were measured.
5 Quality Supervision
5.1 units of state-authorized test anti-static shoes and on the production, conductive shoes and the technical conditions of enterprises, conducting a review of process equipment.Indicators meet the requirements of the enterprise, product testing and officially received the certificate, to produce, sell anti-static rubber-soled shoes, conductive rubber-soled shoes
5.2 Anti-static shoes and conductive rubber-soled shoes factory, shoe factory must soles of the electrical properties of each inspection, meet standards, the shoes to the factory. To have a certificate of qualified products. In each pair of shoes, should be accompanied by simple instructions, indicating performance, range of use, conditions and factory time.
5.3 The inspection authorized by the State reserves the right to the production of anti-static shoes and conductive shoes and regular or irregular sampling inspection. Do not in accordance with the standards of production, poor product quality, enterprise, the examination shall be entitled to a warning or suspension of product certification.
6.1 Anti-static shoes and appropriate parts of the shoe, there must be clearly marked, at the same time help in the shoe, the print "anti-static" word
6.2 Conductive shoes and appropriate parts of the shoe, there must be clearly marked, at the same time help in the shoe, the print "conductive" words. "Anti-static rubber-soled shoes, safety shoes and technical conditions for conducting" the preparation of instructions
