EVS-EN ISO 14122-4:2016

ISO 14122-4 gives requirements for fixed ladders which are part of a stationary machine, and to the non-powered adjustable parts (e.g. foldable, slidable) and movable parts of fixed ladder systems.

This standard can be used by:
— machine manufacturers (small, medium, and large enterprises),
— health and safety bodies (regulators, accident prevention organizations, market surveillance).

ISO 14122-4 specifies minimum requirements that also apply when the same means of access is required as part of the building or civil construction. These can be fixed ladders where the machine is installed, on condition that the main function of that part of the construction is to provide a means of access to the machine.

The ISO 14122 series is applicable to both stationary and mobile machinery where fixed means of access are necessary. It does not apply to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels. ISO 14122-4 does not apply to machinery manufactured before the date of its publication.

The international standard has been approved in Europe as EN ISO 14122-4:2016 without any changes and it supersedes EN ISO 14122-4:2004.
