Technical Info


  • EN ISO 20345: 2011 S3
  • EN 61340-4-3


EN ISO 20345 - This is the European standard relating to safety footwear used for general purposes

There are a host of specific tests conducted as part of EN ISO 20345, including:

Impact Resistance:

A steel weight of 20kg is adapted to fall freely on top of the footwear sample in order to assess the strength of the toe cap. After impact the distance between the toe cap and the insole must range between 12.5 –15mm.

Compression Resistance:

The footwear sample is subjected to a force of 15kN between two steel plates. Upon completion of the test the distance between the toe cap and the insole must range between 12.5 –15mm.

Anti-Penetration Insert:

A force of at least 1100N is applied to a test nail. In order to meet the standard, the tip of the nail must not protrude through the midsole of the footwear sample. A visual inspection is carried out to verify this.

EN 61340-5-1 - Protection of electronic devices from electronic phenomena

What Is EN 61340-5-1?

Static charge can build up on the body for a number of reasons including personal attire, atmospheric humidity and the way in which a person walks and moves. A build up of electrostatic discharge (ESD) can damage sensitive electronic components or create fire risks when handling solvents and other flammable materials.


In order for electrostatic sensitive devices (ESDS) to be handled with minimal risk of damage there are specific technical requirements for the design, use and control of an electrostatic protected area (EPA). This includes the use of ESD control items such as garments or footwear.

How Is It Tested

Compliant garments must be clearly marked and must completely cover all clothing in the arms and torso region. The point to point resistance over the outer surface must be less than 1012 Ω.

Point to Point Resistance

The point to point resistance is a measure of the conductivity of the material between two points. Conductive fibres in garments work by preventing the static charge build up by allowing it to dissipate through the conductive fibres and go to earth.

Lower is Better

The lower the resistance the higher the conductivity and the lower the risk of electrostatic discharge.
