  Description:

Safety of machinery - Permanent means of access to machinery - Part 3: Stairs, stepladders and guard-rails (ISO 14122-3:2016)

  Purpose

ISO 14122-3 gives requirements for non-powered stairs, stepladders and guard rails which are part of a stationary machine. It is intended to be used by machine manufacturers and health and safety bodies. ISO 14122-3 specifies minimum requirements that also apply when the same means of access is required as part of the building or civil construction (e.g. stairs, stepladders, guard rails) where the machine is installed. Where no local regulation or standards exist, ISO 14122-3 may be used also for means of access which are not described in this standard. It is intended that the standard be used with ISO 14122-1 to give the requirements for steps, stepladders and guard rails. 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 14122-3 does not apply to machinery manufactured before the date of its publication. The international standard has been approved in Europe as EN ISO 14122-3:2016 without any changes and it supersedes EN ISO 14122-3:2001.
