27、andards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International o
28、rganizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for i
29、ts further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/d
30、irectives).Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in

33、els and replaces the first edition (ISO 14122-3:2001) which has been technically revised. It also incorporates the Amendment ISO 14122-3:2001/Amd 1:2010.ISO 14122 consists of the following parts, under the general title Safety of machinery Permanent means of access to machinery: Part 1: Choice of fi

35、ctionThis International Standard is a type-B standard as stated in ISO 12100. It is relevant, in particular, for the following stakeholder groups representing the market players with regard to machinery safety: machine manufacturers (small, medium and large enterprises); health and safety bodies (re
36、gulators, accident prevention organizations, market surveillance, etc.).Others can be affected by the level of machinery safety achieved with the means of this International Standard by the above-mentioned stakeholder groups: machine users/employers (small, medium and large enterprises); machine use
37、rs/employees (e.g. trade unions, organizations for peoples with special needs); service providers, e.g. for maintenance (small, medium and large enterprises); consumers (in case of machinery intended for use by consumers).The above-mentioned stakeholder groups have been given the possibility to part
38、icipate at the drafting process of this International Standard.In addition, this International Standard is intended for standardization bodies elaborating type-C standards. The requirements of this International Standard can be supplemented or modified by a type-C standard.For machines which are cov
39、ered by the scope of a type-C standard and which have been designed and built according to the requirements of that standard, the requirements of that type-C standard take precedence.The purpose of this International Standard is to define the general requirements for safe access to machines. ISO 141
40、22-1 gives guidance about the correct choice of access means when the necessary access to the machine is not possible directly from the ground level or from a floor or platform.The dimensions specified are consistent with established ergonomic data given in ISO 15534-3.

42、 non-powered adjustable parts (e.g. foldable, slidable) and movable parts of those fixed means of access.NOTE 1 “Fixed” means of access are those mounted in such a manner (for example, by screws, nuts, welding) that they can only be removed by the use of tools.This part of ISO 14122 specifies minimu
43、m requirements that also apply when the same means of access is 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 the construction is to provide a means of access to t
44、he machine.NOTE 2 Where no local regulation or standards exists, this part of ISO 14122 may be used also for means of access which are outside the scope of the standard.It is intended that this part of ISO 14122 be used with ISO 14122-1 to give the requirements for steps, stepladders and guard-rails
45、.The ISO 14122 series as a whole is applicable to both stationary and mobile machinery where fixed means of access are necessary. It is not applicable to powered means of access such as lifts, escalators, or other devices specially designed to lift persons between two levels.This part of ISO 14122 i
46、s not applicable to machinery manufactured before the date of its publication.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
