EN ISO 20345

Safety norm for safety footwear for professional use — The regulations to which safety footwear needs to comply have been determined in the European Safety Standards (safety norm EN ISO 20345). All shoes that fall under these norms, need to be equipped with – at least – some basic requirements. The mark ‘S’ stands for ‘safety’. All our safety footwear protects against toecap impact up to an energy level of 200J against sole penetration. All used components are tested and selected according to the European technical requirements with regard to safety, ergonomics, comfort and quality. Please always check whether the product complies with your work’s safety requirements. Read the manual thoroughly before first use. This manual comes with every pair of shoes.

S1: Safety class S1 (SB + A + E + FO + Closed heel)

Safety footwear should always comply with the EN ISO 20345 safety requirements.

Obligatory characteristics:
Work shoes with S1 certification have a reinforced safety toe made of steel or composite, a closed heel and antistatic sole with hydrocarbon resistance. With an energy absorbent heel, you can work comfortably on every job. 

S1P: Safety class S1P (S1 + 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.  

S1P shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S1 
• The extra feature P

S2: Safety class S2 (S1 + 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 and absorption of water. 

S2 shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S1 
• The extra feature WRU

S3: Safety class S3 (S2 + P + Cleated outsole)

S3 shoes have the following features:

• All basic features for safety shoes
• All extra features in safety class S2 
• The extra feature P
• Cleated outsole

S5: Safety class S5 (S3 + WR) 

S5 Safety Footwear offers all-round protection of the highest safety level.
The plastic or rubber boots offer the same features as the safety shoes in S3 and are additionally fully waterproof.

A Antistatic features	P Anti perforation sole	E Energy absorption in the heel	FO Sole has resistance to hydrocarbons
WR Whole footwear is resistant to water penetration and absorption	WRU Only upper material is resistant to water penetration and absorption	Closed Heel	Cleated outsole

HEROCK® Shoe Overview

Antiperforation Midsole

THE ANTI PERFORATION MIDSOLE IS AN IMPENETRABLE MIDSOLE THAT PROTECTS THE FEET AGAINST PENETRATIONS THROUGH THE SOLE OF THE SHOE. OUR USED ANTI PERFORATION MIDSOLES ARE IN ACCORDANCE WITH EN ISO 20345: 2011.

For the moment there are two generic types of impenetrable inserts for PBM-shoes. One made of metal material and one made of non-metal material; both types meet the minimum requirements for penetration resistance (standard EN ISO 20345), each with its own characteristics :

• Metal insert-soles are less subject to sharp objects/danger (in width, geometrics, sharpness), but they do not cover the whole sole of the shoe due to production limitations.
• Non-metal insert-soles are lighter and more flexile and cover more of the sole surface. The penetration resistance can be different, depending on the sharp objects/danger (width, geometrics, sharpness). The insert-soles cannot be traced by metal detectors and they provide you with thermal insulation and regulate temperature.

Apart from the different midsoles we distinguish three kinds of safety toecaps. They all comply with the EN ISO 20345 requirements.
The most important requirement is energy impact resistance up to 200 J. The biggest difference in the safety toecaps is the weight.

Antistatic safety shoes and boots have a low electrical resistance between 0.1 and 1000 MegaOhm (MΩ). The use of anti-static safety footwear helps prevent a build-up of static electrical charges in the human body by sending these charges to the ground, preventing a sudden flow of electricity between electrically charged objects caused by contact. Antistatic safety footwear should not be confused with ESD (Electrostatic Discharge) footwear. Both terms refer to contact resistance but there are fundamental differences between the two !

For more information about anti-static safety footwear, please read carefully our user instructions.

The SR certification on safety footwear tells you how good the grip of the outer sole is. It is tested on different surfaces and with various liquids.

	SRA : Tested on ceramic tile floor wetted with a diluted soap solution
	SRB : Tested on steel floor with glycerol
	SRC : Tested under both SRA and SRB conditions
