This part of ISO 14122 gives requirements for non-poweredstairs, stepladders and guard-rails which are a part of astationary machine, and to the non-powered adjustable parts (e.g.foldable, slidable) and movable parts of those fixed means ofaccess. NOTE 1 ?Fixed? means of access are those mounted in such amanner (for example, by screws, nuts, welding) that they can onlybe removed by the use of tools. This part of ISO 14122 specifiesminimum requirements that also apply when the same means of accessis required as the part of the building or civil construction (e.g.stairs, stepladders, guard-rails) where the machine is installed,on condition that the main function of that part of theconstruction is to provide a means of access to the machine. NOTE 2Where no local regulation or standards exists, this part of ISO14122 may be used also for means of access which are outside thescope of the standard. It is intended that this part of ISO 14122be used with ISO 14122-1 to give the requirements for steps,stepladders and guard-rails. The ISO 14122 series as a whole isapplicable to both stationary and mobile machinery where fixedmeans of access are necessary. It is not applicable to poweredmeans of access such as lifts, escalators, or other devicesspecially designed to lift persons between two levels. This part ofISO 14122 is not applicable to machinery manufactured before thedate of its publication.
