Technical requirements for anti-static shoes
1.Wearing place 1.1 Anti-static rubber sole shoes Anti-static rubber sole shoes are mainly used to prevent burning and explosion of the human body due to static electricity(for example,rubber,chemical,printing,medical,electronics,etc.)place).At the same time,it can also avoid electric shock and fire to the human body caused by accidental electrical equipment below 250V.
1.2 It is forbidden to wear anti-static rubber sole shoes for workers who are in danger of maintaining electric equipment or handling high-voltage electrical equipment.
2,performance indicators 2.1 electrical performance indicators during the wearing of shoes,according to GB4386-84"anti-static rubber sole shoes,conductive rubber soles resistance measurement method"to measure.The resistance of the sole of the antistatic rubber sole must be in the range of 0.5×10^5Ωto 1.0×10^8Ω.
2.2 Other performance indicators 2.2.1 Other performance requirements of anti-static rubber sole shoes and conductive rubber sole shoes must meet the national standards and technical requirements of the corresponding footwear.
2.2.2 When designing and selecting materials for antistatic rubber sole shoes and conductive rubber sole shoes,it must be considered that the resistance of the sole of the shoe is minimally changed under the influence of wear and pollution.
2.2.3 Anti-static rubber sole shoes and conductive rubber sole shoes with special requirements(for example,need to have acid,alkali,oil and other properties)should also meet the corresponding technical standards.
3.Wear requirements 3.1 To ensure the elimination of static electricity from the human body,when wearing anti-static rubber-soled shoes,the resistance of the ground should be no more than 1.0×10^8Ω;when wearing conductive rubber-soled shoes,the resistance of the ground It should be no more than 1.5×10^5Ω.
3.2 In the process of wearing the shoes,the bottom of the anti-static rubber sole shoes and conductive rubber sole shoes shall not be exposed to insulating impurities.
3.3 During the wearing of the shoes,take care to avoid wearing thick socks with strong insulation or wool,as well as insulating insoles.
