Knee protection - EN 14404:2004+ A1

Knee protection clothing

This standard defines the level of protection provided by the protective reinforcement AND the trousers, to ensure that the knee pockets are correctly positioned. This is determined through mechanical and ergonomic tests. 

Knee protectors must meet the general requirements when used in the kneeling position as well as when moving around (walking) on the knees. The type of protection must be chosen in line with the intended use: inserted into the trousers (Type 2), worn over the trousers (Type 1) or placed directly onto the floor (Types 3 and 4).

Testing methods are determined based on the performance requirements and three performance levels are defined:

• Level 0: Only suitable for use on flat, smooth floors, offering no protection against penetration.
• Level 1: Suitable for use on flat or non-flat floors, offering protection against rough or sharp objects (up to 1 cm) lying on the floor. This level of protection offers resistance against penetration at a force of at least (100 ± 5) N.
• Level 2: Suitable for use on flat or non-flat floors in severe conditions such as rubble, broken rocks or mines, offering protection against rough or sharp objects greater than 1 cm. This level of protection offers resistance against penetration at a force of at least (250 ± 10) N.
