EN ISO 20345: 2011 - Personal Protective Equipment, Safety Footwear

The CE mark denotes that this product complies with the general requirements of the European Personal Protective Equipment Regulation (EU) 2016/425 in terms of safety, comfort and wear resistance.

It is important to ensure that the footwear selected is suitable for the work-environment and the protection required. The Ironsteel footwear has been CE type-tested by a competent institute (notified body) and one of the two mentioned categories of the CE marking will be shown:

EN ISO 20347:2012 - Work Shoe Requirements

EN ISO 20345:2011 - Safety Shoe Requirements

The individual classes within the norms for work and safety footwear are described below:

EN ISO 20347:2012 OB 
- In terms of solidity and wear resistance, a level of quality as defined by an agreed European Standard
- Basic work shoes
- Fuel Oil resistant outer sole (FO) *

EN ISO 20345:2011 SB
- In terms of comfort and wear resistance, a level of quality as defined by an agreed European Standard
- The presence of a safety toecap providing protection against impact injury to the toes caused by falling objects, the toes being trapped under a heavy object, etc.
- Level of protection: 200 Joules / 15 kN

EN ISO 20345:2011 S1
- As above SB standard, plus closed seat region
- Anti-static properties (A)
- Energy absorption of seat region (E)
- Fuel Oil resistant outer sole (FO) *

EN ISO 20345:2011 S1-P
- As above S1 standard, plus penetration resistance (P)

EN ISO 20345:2011 S2
- As above S1 standard, plus water-penetration and absorption resistance (WRU) **
- Non-Cleated outer sole

EN ISO 20345:2011 S3
- As above S2 standard, plus penetration resistance (P)
- Cleated outer sole

*) Fuel resistance (FO) is tested on the rubber outsole, not on the EVA / Phylon midsole as it is not in direct contact with the surface.

**) The water penetration and absorption (WRU) properties only apply to the upper materials for S2 / S3 styles and do not guarantee full water resistance for the entire footwear.

Slip resistance according to the EN ISO 20345:2011

The following markings show on which ground the footwear provides protection (how much friction):
- SRA: On ceramic tile floor incl. Sodium Laurel Sulphate (SLS) solution
- SRB: On steel ground incl. Glycerol
- SRC: Both SRA and SRB 

Marking Tested features  Test Coefficient of friction
SRA Slip resistance on ceramic tiles with soap solution (SLS)

Slide forward with the whole shoe on a flat surface

Slide forward with heel

Not more than 0,32

Not more than 0,28


SRB Slip resistance on steel ground with Glycerol

Slide forward with the whole shoe on a flat surface

Slide forward with heel

Not more than 0,18

Not more than 0,13


SRC Both SRA and SRB Tests both for SRA and SRB As above


If the footwear is marked with SRA, SRB or SRC, the user, as responsible, must always take into account the work conditions and the substrate. If there is no marking (SRA, SRB, SRC), the footwear should be used on soft surfaces such as soil, sand and the like.

Some other symbols used within EN ISO 20345:2011:

- Conductive footwear (C)
- Outsole resistant to hot contact max 300° C for 1 min (HRO)
- Heat insulation up to max. 150° C for 30 min. (HI)
- Cold insulation up to max. -17° C for 30 min. (CI)
- Water penetration and water absorption of the upper part of the shoes (WRU) **
- Water repellent construction (WR)

Production date presented on label: The figures "MM / YY" represent the month and year the footwear was produced. The production period is included together with the CE marking in the footwear.

If there is included a factory symbol on any label, it represents the production and is shown together with the responsible unit.
