scope:

This International Standard is applicable to stationary machinery where fixed means of access are necessary. This part of ISO 14122 applies to working platforms and walkways which are a part of a machine. This International Standard may also apply to means of access to that part of the building (e. g. working platforms, walkways, ladders) where the machine is installed, providing the main function of that part of the building is to provide a means of access to the machine. NOTE 1 If no national standard or regulation is applicable this standard may be used also for means of access are outside the scope of this standard. This International Standard is applicable also to non-powered adjustable parts (e. g. foldable, slidable) and to the movable parts of fixed means of access This International Standard is not applicable to machinery manufactured before the date of its publication. NOTE 2 For mobile machinery, due to their dimensions and particular conditions of use, specific requirements deviating from this standard can be applied. Therefore it is intended to develop a standard for mobile machinery excluding mobile machinery used in rough terrain. For access to mobile machinery used in rough terrain such earth moving machinery see ISO 2867 and for agriculture machinery see ISO 4254-1.
