Safety Norm For Safety Shoes

1. EN ISO 20345: 2004

All requirements for safety shoes have been established in the European safety norms. Safety norm ISO 20345 defines the requirements that all new safety shoes have to meet. All safety shoes that are licensed under this norm need to answer to a very specific set of demands. The ‘S’ in every type represents the shoe’s safety factor.
 

S1: Safety class S1 (A+FO+E)

All shoes of the S1 type meet the basic demands for safety shoes:

• The height of the upper fabric
• Protective nose (with a minimum length and width)
• Upper fabric needs to be leather or equivalent synthetic material
• Needs to have inner lining
• Sole can be made out of any material and can be smooth
• Upper fabric can be open on low shoes

S1 shoes have the following features:

• Closed zone on the heel
• Antistatic features
• Energy absorption in the heel
• Sole is resistent to hydrocarbons
   

S2: Safety class S2 (A+FO+E+WRU)

Safety shoes of the S2 type have the same features as the shoes in safety class S1 with the addition of an extra quality: resistance of the upper material against penetration by foreign objects and absorption of water.

S2 shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S1 (A+FO+E)
• The extra WRU feature
   

S3: Safety class S3 (A+FO+E+WRU +P)

Safety shoes of the S3 type have the same features as the shoes in safety class S2 with the addition of an extra quality: • Anti-perforation sole

S3 shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S2 (A+FO+E)
• The extra P feature

S1P: Safety class S1P (A+FO+E+P)

Safety shoes of the S1P type do not have their own safety class, but because they are used so frequently, they get a separate mention here. These safety shoes are all based on the S1 safety class with an anti-perforation sole as additional feature

S3 shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S1 (A+FO+E)
• The extra P feature
