EN 516:2006 (E) 5 1 Scope This document applies to installations for roof access (building products) permanently fixed to the load-bearing construction of pitched roofs, to stand or to walk on d
28、uring inspection, maintenance and repair of facilities on the roof. It specifies essential dimensions, materials to be used, requirements with respect to the load-bearing capacity of the installation for roof access fastened to the roof construction including their fastening system, and the extent o
29、f testing. This document does not apply to permanently fixed ladders on pitched roofs. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of

32、r to walk on with one or more supports permanently fixed by means of associated fastening systems to the load-bearing construction of a pitched roof Note 1 See figure 1 Note 2 Depending on the size of the platform, installations for roof access are designated as walkways (see Figure 2), treads (see
33、figure 3) or steps (see figure 4) 3.2 fastening system combination of products which fasten the walkways, treads and steps, to the load-bearing roof construction 3.3 load-bearing roof construction part of the roof construction which is able to carry potential loads and to transmit them to the buildi

The material
35、 shall be free from faults and inclusions that may impair their performance abilities. The corrosion resistance shall be at least equivalent to that of hot-galvanised steel with a protective layer according to EN ISO 1461. Parts of the fastening system beneath the roof covering may be from timber an
36、d shall then be protected against atmospheric and climatic influences. 6 Dimensions and construction requirements 6.1 General Installations for roof access shall be classified as follows: Class 1: Installations that shall not be used as anchorage points to which personal protective equipment against
37、 fall or for restraint are attached; Class 2: Installations that may be used as anchorage points to which personal protective equipment against fall or for restraint are attached. The surfaces of the platforms of walkways, treads and steps shall be designed to avoid slipping of persons and collectio
38、n of water and, where necessary, to minimise snow build-up. Constructions with sharp angles or edges have to be avoided. To accommodate roofs with different slopes, the connections between platform and supports shall be adjustable but they shall be designed to be secured against accidental disconnec
39、tion after installation. The type and size of the fastening system(s) shall be specified by the manufacturer. 6.2 Walkways Walkways are distinguished according to the width of their platforms as types A, B or C. The minimum width b of the platform shall be for: Type A: 250 mm, Type B: 350 mm and Typ
40、e C: 430 mm. The length l of the platforms of all types shall be at least 500 mm. EN 516:2006 (E) 7 The platforms of walkways of Type B shall be provided with turn-ups or side battens of at least 20 mm on both long sides, measured from the platform surface, to prevent persons from slipping. The supp
41、orts of walkways shall be designed in such a way that, after mounting on the roof construction, the inclination across the width b as well as across the length l is not greater than 3 from the horizontal. 6.3 Treads The platform of treads shall have a width b of at least 250 mm. The length l shall b
42、e at least 400 mm. The supports of treads shall be designed in such a way that, after mounting on the roof construction, the inclination across the width b as well as across the length l is not greater than 3 from the horizontal. 6.4 Steps The platform of steps shall have a size b l of at least 130
43、mm 130 mm. On all sides, except the front and rear side, the platform of steps shall be provided with turn-ups or side battens of at least 20 mm, measured from the platform surface, to prevent persons from slipping. Furthermore, steps shall have a handle or a grip hole in the platform. The supports
44、of steps shall be designed in such a way that, after mounting on the roof construction, the inclination across the width b as well as across the length l is not greater than 3 from the horizontal.

46、 and 2 Installations for roof access of Classes 1 and 2 including their fastening systems shall be designed for a single vertical static load of P 1,5 kN, applied in the most unfavourable position. Compliance with the requirements shall either be proved by means of a static calculation or, if this i
47、s not possible, the product shall be tested according to Clause 8. NOTE For further calculations see ENV 1993 and ENV 1999. Under this load the vertical deflection of walkways and tread platforms shall not exceed 1/100 of the span. The maximum deflection shall not exceed 15 mm. The vertical deviatio
48、n from the original position of treads and steps, measured over the supports, shall not exceed 9 mm. The vertical deflection and/or deviation shall be measured relative to the load-bearing construction. Installations for roof access of Class 2 and their fastening systems shall be designed for a sing
49、le static load of P1 10 kN applied in a possible anchorage point in the usage direction. The test load according to EN 795 shall be increased accordingly if the installation for roof access of Class 2 is used by more than one person. 7.2 Fatigue strength Installations for roof access of Class 2 including their fastening systems shall be designed to withstand the dynamic load of the test according to 8.2 at any point where it is possible to attach personal protective e
