The National Bureau of standards, 1984-05-14 released 1985-01-01 implementation
This standard applies to the flammable, explosive and other places, workers for the elimination of static electricity on human body while wearing anti-static
Rubber soled shoes and conductive rubber soled shoes.
The standards are the light of the ISO2251 and ISO2024 formulation
In 1 places
1.1 anti-static shoes
Anti-static shoes is mainly used to prevent human body electrostatic and may cause fire, explosion places (e.g., rubber, chemical industry, printing, medical, electronic and other industries in some places ). At the same time, it also can avoid because 250V following electrical equipment are occasionally caused by the shock to human body and fire.
The 1.2 conductive rubber soled shoes
Conductive rubber soled shoes is mainly used to prevent human body electrostatic and cause a fire, explosion places ( for example, explosive industry in some places ). But it is only applicable to the operation personnel will not be subjected to electroshock places.
1.3 for the maintenance of power equipment or processing of high voltage electrical equipment with electric shock hazard to staff, banned the wearing of anti-static shoes, conductive rubber soled shoes.
2 performance indexes
The 2.1 electrical performance index
2.1.1 anti-static shoes
In shoes, according to GB4386-84" anti-static shoes, conductive rubber soled shoes resistance measurement method" for measuring. Anti-static shoes sole resistance must be in a 0.5 x 10 ^ 5 to 1 x 10 ^ 8 Omega Omega range.
2.1.2 conductive rubber soled shoes
In shoes, according to GB4386-84. Conductive rubber shoe sole resistance values must not be larger than 1.5 x 10 ^ 5 omega.
2.2 other performance indicators
2.2.1 anti-static shoes, conductive rubber soled shoes and other performance requirements, must conform to the relevant national standards and technical requirements for footwear.
2.2.2 anti-static shoes, conductive rubber soled shoes structure design and selection of materials used, consideration must be given to the sole of the resistance in wear, pollution under the influence of the smallest change.
2.2.3 on some special requirements of anti-static shoes, conductive rubber shoes (for example, with acid, alkali, oil and other performance ) should be consistent with the relevant technical standard.
3 wear requirements
3.1 to ensure elimination of human body electrostatic effect, wear anti-static shoes, the ground resistance should be less than 1 x 10 ^ 8 omega; wear conductive rubber soled shoes, the ground resistance should be less than 1.5 x 10 ^ 5 omega.
3.2 in the process of shoes, anti-static shoes, conductive rubber shoe bottom not stained with insulation impurities.
3.3 in shoes wearing process, pay attention to avoid while wearing high insulating property or wool thick socks, and insulated insole.
The 4 sole electrical performance test
Anti-static shoes, conductive rubber shoe sole resistor value should be specified in the GB4386-84 method, procedures for the measurement of.
5 quality supervision
The 5.1 countries authorized inspection units for the production of anti-static shoes, conductive rubber soled shoes enterprises technical conditions, process equipment review. The enterprise meets the requirements, and formal inspection certificate of product, to production, sales of anti-static shoes, conductive rubber soled shoes.
5.2 anti-static shoes, conductive rubber shoe factory, factory must be on each shoe sole electrical performance testing, up to standard requirements, the shoe can be manufactured. Qualified products to be certified. In each pair of shoes, should be accompanied by a simple description, description of product performance, scope, conditions and delivery time.
The 5.3 countries authorized inspection units have the right to the production of anti-static shoes, conductive rubber soled shoes regularly or irregularly sampling inspection. Not in accordance with the standards of production, poor product quality enterprises, the inspection units have the right to issue a warning or revoke the certificate of product.
6 mark
6.1 anti-static shoes
In the shoes of the appropriate site, have obvious signs, while in the shoes help, print "static".
The 6.2 conductive rubber soled shoes
In the shoes of the appropriate site, have obvious signs, while in the shoes help, print" conductive".
" Anti-static shoes, conductive shoes safety technology conditions."
One, the compilation process
" Anti-static shoes, conductive shoes safety technology conditions" is the Ministry of labor and Personnel Labor Protection Bureau of Beijing City Labor Protection Science Research Institute drafting. Accept this task, first of all the static defence sneakers and a conductive rubber shoes production and use of the key investigation, and collect, check the relevant information at home and abroad, set the standards needed to be studied in the project and experiment scheme, and then establish the experimental apparatus, experimental study. On the basis of the above work, the drafting of the national standard" anti-static shoes, conductive shoes safety technology conditions". To be on the safe side, we have the two times to the manufacturers and gunpowder, chemical, aerospace, petroleum, coal and other industries using the departments and tertiary institutions, research departments of nearly one hundred and fifty units issued a draft. On the analysis and study of relevant recommendations based on has been changed. In this work, the Ministry of labor and personnel guidance and support, get domestic related industries to help, promote the work of.
In two, the situation at home and abroad
1 domestic situation
With the development of industry, human body electrostatic induced disasters have received increasing attention. To solve the disaster are important measures of staff wearing anti-static shoes and conductive shoes. In the superior part of units under the guidance, in the domestic powder, electronic, petroleum, chemical and other departments and relevant domestic university, scientific research unit's support, in recent years China has begun production of anti-static shoes and conductive rubber soled shoes. Due to the short history of the production of shoes, shoe technology index, test methods and conditions of use of a series of problems such as no clear, unified regulation. Therefore, anti-static shoes, conductive rubber shoe manufacturers, sales department, the use of units of all hope to have a guiding technical document for everyone to follow. Not only correctly guide shoe production and use, but also on the quality of the product's performance to test, control, to ensure safety. Therefore, development of anti-static shoes, conductive rubber soled shoes standard be imperative.
2 foreign countries
Abroad on electrostatic hazards caused by already seriously, and to some extent the use of anti-static shoes and conductive shoes. Some countries, such as Australia, for anti-static shoes use has clearly defined the scope of.
