EN 20347

Protective occupational footwear.

What is EN 20347 standard?

This standard details basic and additional (i.e., optional) requirements for occupational footwear that will not be exposed to mechanical risks (e.g., impact or compression) 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 against molten metal splash, protection for motorcyclists).


(EN 20347:2011 supersedes NEN-EN-ISO 20347:2004.)

EN 20347 explained

Occupational footwear that complies with EN 20347 does not include toecaps that ensure protection against impact forces and compression loads. These types of footwear are designed for workplaces and activities in which both hazards to feet and toes are not identified during risk assessments.

Footwear is classified according to the following classes:
• Class I – footwear made from leather and other materials, excluding all-rubber and all-polymeric footwear (O1, O2, and O3)
• Class II – all-rubber (i.e. entirely vulcanised), all-polymeric (manufactured in one piece), and hybrid (O4, O5, and OBH = polymeric footwear with another material that extends the upper) footwear
