NBN EN 953+A1:2009

This European Standard specifies general requirements for the design and construction of guards provided primarily to protect persons from mechanical hazards.
The standard applies primarily to machines which are manufactured after the date of issue of this standard.
Attention is drawn to the use of guards to minimise exposure to non-mechanical hazards.
The requirements are applicable if fixed and movable guards are used. The standard does not cover those parts of guards which actuate interlocking devices. These are covered in EN 1088.
This standard does not provide requirements for special systems relating specifically to mobility and ability to lift loads like rollover protective structures (ROPS) and falling-object protective structures (FOPS).
