5、rements. This document (EN ISO 14122-4:2016) has been prepared by Technical Committee ISO/TC 199 “Safety of machinery” in collaboration with Technical Committee CEN/TC 114 “Safety of machinery”. The responsible German body involved in its preparation was DIN-Normenausschuss Maschinenbau (DIN Standar
6、ds 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, stairs, stepladders, guard-rails and ladders, and of the employers liability insurance associa
7、tions 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 machines that are either first placed on the market or commissioned within the EEA. This sta
8、ndard 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” standard and thus, a manufacturer applying this standard may assume compliance with the requirement
9、s 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 as the corresponding DIN EN ISO Standards with the same number. Where the International Stan
10、dards 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 14122-4:2010-12 as follows: a) the standard has been revised in form and substance. The significant technical changes compa
11、red with the previous edition are summarized in tabular form in Annex C (informative); b) information for designers of fixed ladders is given in National Annex NA. Previous editions DIN 23276: 1954-03 DIN 24532: 1970-03, 1981-05 DIN EN ISO 14122-4: 2004-12, 2010-12 DIN EN ISO 14122-4:2016-10 3 Natio
12、nal Annex NA (informative) Information for manufacturers, operators/users and designers A.1 General When planning means of 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 fixed ladders is
13、 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 information take the form of a chec
14、klist. 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 means of access supplied to
15、 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 Editorial notes Subclause 4.1.3: In Subclause 4.1.3, the expression “where obstacles such as pipes or trays cross” does n
16、ot mean bundles of pipes or several trays, but only an individual pipe or an individual tray in each case. In order to avoid misunderstanding, the following formulation should be used: 4.1.3 Spacing between the ladder and any permanent obstruction The space between the ladder and any permanent obstr
17、uction or obstacle shall be (see Figure 4) a) measured from the front of the rungs: 1) in front of the ladder: at least 650 mm or, where obstacles such as a pipe or a tray cross, 600 mm; 2) behind the ladder: at least 200 mm or, where obstacles such as a pipe or a tray cross, 150 mm. The same applie
18、s to the key to Figure 4. Subclause 5.4.5: Since the mode of actuation of the trap door is not illustrated in Figure 13, details of actuation (“(foldable) slidable”) should not be mentioned in the key to avoid misunderstanding. DIN EN ISO 14122-4:2016-10 4 Annex A.1 General The information relating
19、to door systems given in the fifths and last indents should be given in the form of NOTES for better understanding. Thus, the two sentences should read as follows: they shall allow the safe passage of the operator while in the access position; NOTE This means “open”, if door systems are fitted. they
20、 shall return to a position preventing access by self-closing (e.g. spring applied) and self-locking (be locked) after safe passage. NOTE This means “closed and locked”, if door systems are fitted. EUROPEAN STANDARD NORME EUROPENNE EUROPISCHE NORM EN ISO 14122-4 June 2016 ICS 13.110 Supersedes EN IS
