32、122-4:2016(E)ForewordISO (the International Organization for Standardization) is a worldwide federation of national standards 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 f
33、or which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on
34、 all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its 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.
35、 This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). 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 an
36、y or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents). Any trade name used in this document is information given for the convenience of u
37、sers and does not constitute an endorsement.For an explanation on the meaning of ISO specific terms and expressions related to conformity assessment, as well as information about ISOs adherence to the WTO principles in the Technical Barriers to Trade (TBT) see the following URL: Foreword - Supplemen
38、tary informationThe committee responsible for this document is ISO/TC 199, Safety of machinery.This second edition cancels and replaces the first edition (ISO 14122-4:2004), which has been technically revised. It also incorporates the Amendment ISO 14122-4:2004/Amd 1:2010.ISO 14122 consists of the f
39、ollowing parts, under the general title Safety of machinery Permanent means of access to machinery: Part 1: Choice of fixed means and general requirements of access Part 2: Working platforms and walkways Part 3: Stairs, stepladders and guard-rails Part 4: Fixed laddersAn additional part, dealing wit
40、h mobile machinery, is under preparation. ISO 2016 All rights reserved vBS EN ISO 14122-4:2016ISO 14122-4:2016(E)IntroductionThis International Standard is a type-B standard as stated in ISO 12100.This International Standard is of relevance, in particular, for the following stakeholder groups repres
41、enting the market players with regard to machinery safety: machine manufacturers (small, medium, and large enterprises); health and safety bodies (regulators, accident prevention organizations, market surveillance, etc.);Others can be affected by the level of machinery safety achieved with the means
42、 of the International Standard by the above-mentioned stakeholder groups: machine users/employers (small, medium, and large enterprises); machine users/employees (e.g. trade unions, organizations for peoples with special needs); service providers, e.g. for maintenance (small, medium, and large enter
43、prises); consumers (in case of machinery intended for use by consumers).The above mentioned stakeholder groups have been given the possibility to participate at the drafting process of this International Standard.In addition, this International Standard is intended for standardization bodies elabora
44、ting type-C standards.The requirements of this International Standard can be supplemented or modified by a type-C standard.For machines which are covered 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
45、type-C standard take precedence.The purpose of this International Standard is to define the general requirements for safe access to machines. ISO 14122-1 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
46、 from a floor or platform.The dimensions specified are consistent with established ergonomic data given in ISO 15534-3.vi ISO 2016 All rights reservedBS EN ISO 14122-4:2016Safety of machinery Permanent means of access to machinery Part 4: Fixed ladders1 ScopeThis part of ISO 14122 gives requirements
47、 for fixed ladders which are a part of a stationary machine, and to the non-powered adjustable parts (e.g. foldable, slidable) and movable parts of fixed ladder systems.NOTE 1 “Fixed” means of access are those mounted in such a manner (for example, by screws, nuts, welding) that they can only be rem
48、oved by the use of tools.This part of ISO 14122 specifies minimum requirements that also apply when the same means of access is required as the part of the building or civil construction (e.g. fixed ladders) where the machine is installed, on condition that the main function of that part of the cons
49、truction is to provide a means of access to the 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 fixed ladder systems.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,
