5、A comma is used as the decimal marker. National foreword This standard includes safety requirements. This document (EN ISO 14122-3:2016) has been prepared by Technical Committee ISO/TC 199 “Safety of machinery” in collaboration with Technical Committee CEN/TC 114 “Safety of machinery”. The responsib

6、le German body involved in its preparation was DIN-Normenausschuss Maschinenbau (DIN Standards Committee Mechanical Engineering), Working Committee NA 060-48-11 AA Arbeitsbhnen und Zugnge Sicherheit of Section Grundnormen. Representatives of manufacturers and users of working platforms, walkways, st

7、airs, stepladders, guard-rails and ladders, and of the employers liability insurance associations contributed to this standard. This standard contains specifications giving detail to the essential requirements set out in Annex I of the “Machinery Directive”, Directive 2006/42/EC, and which apply to

8、machines that are either first placed on the market or commissioned within the EEA. This standard serves to facilitate proof of compliance with the essential requirements of that directive. Once this standard is cited in the Official Journal of the European Union, it is deemed a “harmonized” standar

9、d and thus, a manufacturer applying this standard may assume compliance with the requirements of the Machinery Directive (“presumption of conformity”). The International Standards referred to in Clause 2 and the Bibliography, and which have been taken over as European Standards, have been published

10、as the corresponding DIN EN ISO Standards with the same number. Where the International Standards and documents referred to are not also DIN ISO Standards with the same number, there are no national standards available. Amendments This standard differs from DIN EN ISO 14122-3:2002-01 and DIN EN ISO

11、14122-3/A1:2010-12 as follows: a) the standard has been revised in form and substance. The significant technical changes compared with the previous edition are summarized in tabular form in Annex A (informative); b) a national footnote has been included indicating that not only letter symbol “w”, bu

12、t also “W” is commonly used to denote the clear width; c) information for designers of stairs, stepladders and guard-rails is given in National Annex NA. Note: In ISO 14122-3:2016, subclause number 8.2.2 is erroneously assigned for “Loads” as well as for “Testing procedure” without, however, having

13、any effect on the technical context. In the German translation, this error has been corrected. Previous editions DIN 24535: 1970-03 DIN 24533-1: 1970-03 DIN 31003: 1981-02 DIN 24530: 1981-05, 1991-10 DIN 24533: 1984-04 DIN EN ISO 14122-3: 2002-01 DIN EN ISO 14122-3/A1: 2010-12 DIN EN ISO 14122-3:201

14、6-10 3 National Annex NA (informative) Information for manufacturers, operators/users and designers A.1 General When planning access to machinery, care should be taken to ensure that, in compliance with EN ISO 12100, all relevant information necessary for the design and construction of stairs, stepl

15、adders and guard-rails is provided by the operator/user. This applies in particular to information regarding limits of use, spatial limits and other limits, such as the ambient conditions forming the basis for appropriate material selection. It is, therefore, recommended that the required informatio

16、n take the form of a checklist. It should be noted that the respective specific part or parts of this standards series are to be seen in connection with Part 1 which specifies the order for the selection of the means of access to machinery and the general requirements for the means of access. For me

17、ans of access supplied to countries outside the European Economic Area (EEA), the national regulations of these countries can also be relevant, e.g. those which should be included in a specification. A.2 Special notes for stair designers When designing a stair care should be taken to ensure that the

18、 clear width w (see 3.1.14 and Figure 1) is not used as reference quantity for the stair width B and the space requirement P, but that, depending on the stair design, elements such as stringers, guard-rails and handrails and the necessary clearance (see 7.2.1.5) significantly influence the stair wid

19、th B and thus space requirement P. In addition, sufficient space for assembly work should be taken into account. This applies in particular for stairs that are bounded by walls positioned on the left and on the right. An example for the interrelation between clear width, width and the space requirem

20、ent of a stair is shown in Figure NA.1. DIN EN ISO 14122-3:2016-10 4 Key w clear width B stair width P space requirement 1 stringer 2 guard-rail 3 minimum distance between guard-rail and obstacle Figure NA.1 Example for the interrelation between clear width, width and space requirement of a stair A.

21、3 Editorial notes Subclause 7.1.5: In Subclause 7.1.5, the term “are fitted” (German term “angebracht sind”) should be used instead of “are used” (German term “verwendet werden”). The requirement thus reads: “7.1.5 When vertical uprights are fitted instead of a knee rails see Figure 2b), the clear h

22、orizontal distance between those uprights shall be 180 mm maximum.” EUROPEAN STANDARD NORME EUROPENNE EUROPISCHE NORM EN ISO 14122-3 June 2016 ICS 13.110 Supersedes EN ISO 14122-3:2001English Version Safety of machinery - Permanent means of access to machinery - Part 3: Stairs, stepladders and guard
