EN 20346:2014- Personal protective equipment (PPE): Protective footwear 

(EN 20346:2014 supersedes NEN-EN-ISO 20346:2004.)

This standard details basic and additional (i.e., optional) requirements for general-purpose protective footwear (e.g., mechanical risks, slip resistance, thermal risks, and ergonomic design) and for footwear designed for specific professions and worksite conditions (e.g. footwear for firefighters, electrical insulating footwear, protection against chainsaw injuries, protection against chemicals and molten metal splash, protection for motorcyclists).

Protective footwear that complies with EN 20346 is fitted with toecaps to ensure protection against impact when tested at an energy level of at least 100 J and against compression when tested at a compression load of at least 10 kN.

Footwear are classified according to the following classes:
• Class I – footwear made from leather and other materials, excluding all-rubber and all-polymeric footwear (P1, P2, and P3)
• Class II – all-rubber (i.e. entirely vulcanised), all-polymeric (manufactured in one piece), and hybrid (P4, P5, and PBH = polymeric footwear with another material that extends the upper) footwear 

Marking categories for occupational footwear:

Category Class Additional requirements
PB I or II Basic requirements for protective footwear; toe protection against a 100 Joule impact.
P1 I With protective toecap, closed heels, antistatic properties, energy absorption in heel region, fuel oil-resistant outsole. Use in dry working conditions.
P2 I Same as P1 plus water penetration and water absorption (waterproof shaft up to 60 minutes). Designed for use in humid/wet working conditions.
P3 I Same as P2 plus penetration resistance and cleated outsole.
P4 II Boots with basic requirements plus antistatic properties, energy absorption in heel region, and liquid-tight.
P5 II Same as P4 plus penetration resistance and cleated outsole.
PBH II Same as P4 or P5.
