4、ve a handhold at one side. Stairs with more than three steps and widths fl 900 mm shall be provided with railings or hand rails at both sides. In the case of stairs outside the passenger areas and which have a breadth f, I 900 mm, one railing or hand rail needs to be provided. Railings of stairs sha

5、ll be designed according to EN 71 1. Hand rails shall be fixed at a height of 950 f 50 mm. In the passenger area, an additional hand rail for children shall be provided at a height of 650 f 50 mm.

NOTE If the construction permits, the headroom kshouid be at least 2 100 mm. 4.9 Strength Stairs shall be permanently installed. Steps in the working area shall be designed for a single

9、 load of 13 kN each and in the passenger area for 2,O kN each. If the expected load of 5 kN/m2 leads to greater values, these shall be the basis for calculation The fixed stairs shall withstand a load which corresponds to 100 % of the total of the step loads without producing permanent deformation.

10、For treads and platforms adjacent to stairs, a load (imposed load) of 5 kN/d shall be assumed. 5 Manufacturers declaration The manufacturer has to declare that the stair is constructed conforming to this standard. 6 Designation Stairs shall be designed in conformance with the following details: a) D
