Boarding ladders are used on inland navigation vessels for climbing into ship

19、s boats, disembarking or crossing over onto vessels with lower decks. They are not intended for use by passengers. Boarding ladders are generally required for vessels having a boarding height greater than 1,5 m above the light water-line. They may be used up to a height of around 3,0 m above the lig

20、ht water-line. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendmen

25、Component for hanging the boarding ladder from the shipside. 4 Safety requirements 4.1 Design Boarding ladders are not expected to conform to the designs illustrated here; compliance is only required in the case of the dimensions and specifications given. 4.1.1 Steps The steps shall be slip-resistan

26、t. 4.1.2 Handrail 4.1.2.1 The handrail shall be made from tubular section. 4.1.2.2 The handrail shall only be fitted on one side, the right hand side as one ascends. 4.1.2.3 The handrail shall be run parallel to the string from the third step from the bottom and attached to the string between the se

27、cond and third step from the bottom. 4.1.2.4 It shall be possible to grip the handrail horizontally at its upper end. 4.1.2.5 The handrail shall be connected at its upper end to the hook. 4.1.3 Spacer 4.1.3.1 Where the spacer comes into contact with the shipside, it shall be designed so that the con

28、tact surface is not less than 500 mm wide or the contact points are at least 500 mm apart. 4.1.3.2 The spacer shall be attached to the two strings. If it is of the folding type, it shall be capable of being locked in its operating position. 4.2 Dimensions See figure 1 and table 1. Edges shall be rou

29、nded to min. R 1,5.Page 4 EN 1502 : 1995 BSI 1996 Dimensions in mm General tolerance: ISO 2768-c Data which have not been specified shall be selected as appropriate. Figure 1.

34、terials testing Materials testing shall be by presentation of materials certificates. 5.2 Strength tests A boarding ladder shall be supported by the hooks and held by the spacer so that there is a 75 angle of inclination. 5.2.1 Each step shall be loaded in turn with a 2,5 kN test load. After removin

35、g the load, there shall be no permanent deformation. 5.2.2 The top and bottom step shall be loaded simultaneously with 2,5 kN test loads. After removing the loads, there shall be no permanent deformation. 5.2.3 The boarding ladder is to be fixed before carrying out the test in order to prevent movem

36、ent. The railing shall be loaded with a 500 N test load, effective in any direction, successively at the upper end and at the mid point between attachment points. After removing the load, there shall be no permanent deformation. 5.3 Buoyancy test Buoyancy shall be demonstrated by submerging the boar

37、ding ladder in freshwater. If air is used to provide buoyancy there shall be no leakage of air from the sealed sections. 5.4 Visual and functional inspection All requirements not mentioned under 5.1 to 5.3, shall be verified by visual inspection and practical tests. 6 Designation The designation of

38、a boarding ladder as specified in this standard, having 6 steps shall be: Boarding ladder EN 1502-6 7 Marking Boarding ladders shall be marked by means of a manufacturers plate. The manufacturers plate shall be weather resistant and permanently attached to the inner side of a string. It shall contai

39、n at least the following information. a) Designation: boarding ladder EN 1502 Number of steps. b) Load: permissible deadweight: 2 persons or 150 kg single load. c) Origin: manufacturer or supplier (name, town and country). d) Manufacturing data: serial number and year of manufacture. e) Proof of tes

40、ting: test mark.Page 6 EN 1502 : 1995 BSI 1996 Annex A (informative) A-Deviations A-Deviation: National deviation due to regulations, the alteration of which is for the time being outside the competence of the CEN/CENELEC member. This European Standard does not fall under any Directive of the EC. In

41、 the relevant CEN/CENELEC countries these A-Deviations are valid instead of the provisions of the European Standard until they have been removed. Sweden: In accordance with Regulation n.9 : 1974 of the National Maritime Administration, clause 5.8.2, 5.13.3, 6.8.2.1, 6.12.2.2, the foldable spacer can

42、 put the user in a dangerous position when the ladder is hanging in the hooks and if the spacer is not locked. Therefore a fixed spacer is acceptable only. The handrails should be on both sides.
