DESCRIPTION OF THE SAFETY REQUIREMENTS
Base requirements (SB) include among others:
Tear and abrasion resistance, steam permeability, upper/sole removal resistance, and hydrocarbons sole resistance.

Base requirements (OB) include among others:
Tear and abrasion resistance, steam permeability, and upper/sole removal resistance.

Slip resitant
The friction index of the shoe is tested on different types of slippery floors. Heel and sole are tested.

OPTIONAL REQUIREMENTS
The following requirements are not mandatory for the certification of the shoes, but are needed for some special applications decided by the manufacturer.

Anti-static
These shoes minimise the accumulation of electrostatic shocks by dissipating them, consequently also reducing the risk of fire or explosion when working in environments where flammable substances are present. Additional measures shall be taken if there is the risk of electric shocks.
The electric resistance of this type of shoe can be considerably modified by bending, contamination or humidity.
When using anti-static shoes, the resistance of the ground must be such as not to annul the protection supplied by the shoe itself and no insulating element is to be put between the shoe inner and the foot of the person wearing it.
If an insole is placed between the shoe inner and the foot, the electric properties of the shoe/insole need to be verified.

Energy absorption in the heel area
This is used to reduce the force transmitted by impact to the heel, which may cause harmful effects on long-term.

Water penetration/absorption
This is used in activities subject to frequent contact with water, mud or when exposed to bad weather.
If the worker is continuously in contact with water, then the better choice of shoe is that of type II.

Perforation resistance
The shoes are equipped with anti-perforation soles, fitted within the shoe inner; these soles are sized to guarantee protection right across the sole of the foot.

Conductivity
These are used when the accumulation of electrostatic shocks are to be minimised by dissipating them as quickly as possible.
They cannot be used where there is the risk of electric shocks.
When using conductive shoes, the resistance of the ground must be such as not to annul the protection supplied by the shoe itself and no insulating element is to be put between the shoe inner and the foot of the person wearing it.

Heat insulation
These are used to protect the foot against the effect of external heat.
They must guarantee that the foot remains at a maximum temperature of 22°C for at least 30 minutes when the shoe is in contact with hot ground up to 150°C.

Cold insulation
They are suitable for outdoor work exposed to atmospheric events such as those encountered when working on the road or in woods for example.

Heat by contact resistance
They are suitable for work on hot ground because they have a special sole with relief’s that offer an effective protective insulating action.
The tested resistance to heat by contact is restricted to 300 °C for 1 minute.

Ankle protection
Protects the wearer’s ankles against impact.

Cutting resistance
The bottom of the shoe (from sole to a height of 3 cm) is equipped with additional protection against cutting.
The level of protection is equivalent to protective gloves with a resistance to cutting of 2.

Metatarsal protection
Provides additional protection in the metatarsal area.
