Compare safety shoes standards to understand the use environment of safety shoes

Before understanding the standard of safety shoes, it is necessary to understand the main components of safety shoes:

upper / upper: top leather (with the best air permeability and tension resistance); Bovine split leather (with good air permeability and extensibility)

Baotou: stainless steel / non-metallic composite material

puncture resistant middle sole: stainless steel / non-metallic composite material

sole: double density Pu injection sole (middle sole + big sole); Rubber sole + EVA / PU middle sole; Single density Pu injection sole

European testing standard for safety shoes:

the European standard content replaces the standard EN 1SO 20344:2004

testing methods. This standard specifies the requirements for safety shoes, protective boots and work shoes as well as the testing methods for these types of shoes. This standard shall be used in association with EN 1SO 20345, EN 1SO 20346 and EN 1SO 20347. These three standards stipulate the protection grade and function requirements of the above safety shoes, en344:1992

en344-2:1996en 1SO 20345:2004

safety shoes stipulate the design of safety shoes and the provision of anti smashing safety headgear, 1t can withstand at least 200 Joule impact and 15kn extrusion. En345:1992

en345-2:1996en 1SO 20346:2004

safety shoes are designed and equipped with anti smashing safety bag, 1t can at least withstand the impact of 100 joules and extrusion of 10 kn. En346:1992

en346-2:1996en 1SO 20347:2004

work shoes are different from safety shoes and protective shoes because they are not equipped with safety caps, Therefore, it can not resist impact and extrusion. En347:1992


European safety shoes type standard:

type EN 1SO 20345sb safety shoes are lined with wear-resistant and sweat absorbing steel head, shockproof and sweat absorbing insole, and the soles should have the advantages of wear-resistant, shockproof and skid resistance. Sbpsb safety shoes + puncture resistant insole s1sb + anti-static, heel closed, anti-static, anti-wear and anti-skid Heel energy absorption s1ps1 + anti puncture s2s1 + waterproof s3s2 + anti puncture Anti skid insole

note: S3 safety shoes are the highest level of European safety shoes in EN 1SO 20345 standard. Protection features EN 1SO 20345 standard requires that the anti smashing (impact resistance and pressure resistance) can withstand at least 200 joules of impact and 15 kN of extrusion, and the force required for anti piercing and penetrating the sole shall not be less than 1100n. The anti-static resistance value shall be greater than 105 and less than 109 Ohmic antiskid SRA, SRB, SRC = SRA + SRB insulation (H1) 250 degrees, sustainable 30 minutes heat-resistant contact (HRO) sole heat-resistant 250 degrees

China national standard safety shoes standard:

standard content application place protection toe safety shoes according to ld50-94 standard, the safety performance of inner package head is divided into an1 / an2 / An3 / an4 / an5 five grades, suitable for metallurgy, mining, forestry, port, etc Anti piercing safety shoes for loading and unloading, quarrying, machinery, construction, petroleum and chemical industries are implemented according to the standard of gb12017-1989, and the anti piercing strength is divided into special grade / grade 1 / grade 11, which is suitable for mining, fire protection, construction, forestry, cold work, machinery industries, etc. electric insulating shoes are implemented according to the standard of gb12011-2000, which is suitable for electricians, electronic operators, cable installers, electrical workers, electrical workers, electrical workers and so on Anti static safety shoes for substation installers, etc. shall comply with GB4385-1995 standard, which can eliminate the accumulation of static electricity in human body. Acid and alkali resistant safety shoes for chemical plants, gas station operators, liquefied gas filling workers, etc. shall comply with gb12018-1989 standard, which is applicable to electroplating workers, pickling workers, electrolyzers, liquid dispensers, Chemical operators, etc.
