Here you will find information about the European standards for safety shoes, protective shoes and occupational shoes. The European standards EN ISO 20344, 20345, 20346 and 20347 regulate the basic requirements for safety footwear, protective footwear and occupational footwear for commercial use.
EN ISO 20344: Requirements and test methods for safety, protective and occupational footwear for commercial use
EN ISO 20345: Safety footwear in accordance with this standard has a toe cap whose protective effect against impact is tested with a test energy of 200 joules and a compressive force of 15 kN.
EN ISO 20346: Protective footwear according to this standard has a toe cap whose protective effect against impact is tested with a test energy of 100 joules and a compressive force of 10 kN.
EN ISO 2347: Work shoes without protective toe cap
Categories in EN ISO 20345
All safety shoes designed on www.allprotec.de comply with the requirements of EN ISO 20345. Important categories of safety footwear according to EN ISO 20345 are:
SB A self-service shoe is a basic shoe that meets the minimum requirements of EN ISO 20345, such as tear strength, strength or water vapor permeability, which affect the upper material, lining or shoe in the assembled state.
S1 An S1 shoe meets the requirements of EN ISO 20345. In addition, this safety shoe has a closed heel area, an energy absorption capacity in the heel area and meets the requirements for antistatic.
S1P An S1P shoe meets the requirements of EN ISO 20345 S1, but is also equipped with a puncture-resistant midsole. However, safety shoes according to this standard are not waterproof.
S2 An S2 shoe meets the requirements of EN ISO 20345 S1, but is also suitable for areas where the effects of moisture are to be expected.
S3 An S3 shoe meets the requirements of EN ISO 20345 S2, in addition to a puncture-resistant midsole and a more profiled outsole.
S4 An S4 shoe meets the requirements of EN ISO 20345 S1. In addition, no water must penetrate in the first 15 minutes and it has a profiled outsole.
S5 An S5 shoe meets the requirements of EN ISO 20345 S4, in addition to a puncture-resistant midsole and a more profiled outsole.
Additional requirements are identified as follows:
HI Thermal Insulation
CI Cold Insulation
P Penetration resistance
HRO behaviour towards contact heat
WRU Water penetration and absorption of the upper part of the shoe
Slip resistance for work, protective and safety shoes
Safety shoes are subjected to a slip resistance test, whereby the shoes are pulled over two different surfaces with a lubricant each with a certain pressure. The frictional force generated is measured. The test methods are described in the EN ISO 13287:2007 standard.
Depending on whether the shoe passes the test on tiles, on steel floors or on both floors, the slip resistance is classified with SRA, SRB or SRC
- SRA Slip Resistance on Ceramic Tiles with Cleaning Agents
- SRB Slip Resistance on Steel Floor with Glycerin
- SRC slip resistance on ceramic tiles with detergents and steel floor with glycerin. The SRC value is formed from the SRA and SRB values.
What is ESD?
ESD (electrostatic discharge = electrostatic discharge) is an electrical discharge caused by the transfer of static electricity from one object to another, e.g. by rubbing and separating two different materials.
Environments and areas where ESD shoes are needed include areas with electronically controlled machinery, microchip assembly, microelectronics, clean rooms, the chemical industry and potentially explosive environments.
ESD shoes that meet the requirements of EN 61340-5-1 do not primarily protect people, but electrostatically endangered components in sensitive work areas. According to EN 61340-5-1, the resistance to earth must be between 0.1 – 35 MOhm.
BGR 191
This set of rules sets out the rules of the employers' liability insurance association for the selection, procurement, provision and use of foot protection (safety shoes, protective shoes and occupational shoes, as well as knee protection).
