It lays down design, dimension
23、s, strength and test conditions which have to be observed for safety reasons. These railings provide protection for persons against falling overboard and from one deck to another. 2 Normative references This European Standard incorporates by dated or undated references, provisions from other publica
24、tions. These normative references are cited at the appropriate places in the text and the publications are listed hereafter. For dated references, subsequent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

28、1 Railing 3.1.1 railing in the working area A construction of stanchions, hand rail, intermediate rail and toe rail. 3.1.2 railing in the passenger area A construction of stanchions, hand rail, intermediate rails and toe rail or of stanchions, hand rail and network. 3.2 stanchion The vertical part o
29、f the railing which serves as connection to the deck. 3.3 hand rail The uppermost continuous part of the railing serving as handhold against falling overboard and for holding on. 3.4 intermediate rail A continuous part fixed between hand rail and deck to prevent a person from slipping below the hand
30、 rail. 3.5 network A construction of netting, plate or vertical bars filling up entirely or to a large extent the range between hand rail and deck. 3.6 toe rail A profile fitted to the deck to prevent feet slipping through at the railing. 4 Safety requirements 4.1 Design The railing design depends o
31、n location as shown in table 1. If there is a coaming (face plate or projecting skin plate) in appropriate distance to the place where a railing shall be mounted, a special toe rail is not necessary (see figure 1). 4.2 Safety dimensions Dimensions in mm General tolerances: ISO 2768-c Details not ind
32、icated are to be suitably selected. Dimensions complying with figure 1 and table 2.

43、hich are liable to cause injuries. 4.4.2 Railings of types CT, CD shall be constructed in such a way that there is no risk of stumbling in the area of connectors, stanchions and ropes when railings are tilted or detached. Special attention is to be paid to a constant tension of ropes. Hand rail and
44、intermediate rail shall be tensionable in such a way that deflection will not exceed 200 mm when a force of 200 N is acting between two stanchions. 4.4.3 Water drainage from deck shall be ensured even if there are toe rails or coamings. 4.4.4 Stanchions can be suitably reinforced in the lower range,
45、 e.g. by pressed tubes or round steel bars. 4.4.5 Stanchions of railings of type CD shall be protected against unintentional detachment. 5 Materials 5.1 Choice of materials Certain materials have not been specified. Strength requirements according to table 3 shall be observed. 5.2 Example of railing
46、 made of steel Steel profiles specified in table 4 can be used for stanchions, hand rails and intermediate rails. If these dimensions and material qualities are selected, a special strength calculation is not necessary. For other material qualities (e.g. steel of lower strength, aluminium) table 4 d
47、oes not apply. Licensed Copy: sheffieldun sheffieldun, na, Tue Nov 07 03:50:38 GMT+00:00 2006, Uncontrolled Copy, (c) BSI Page 6 EN 711 : 1995 BSI 1996 Table 3.
