They are intended for the attachment of
21、slaters ladders, for supporting working platforms and as anchorage points to which personal protective equipment against falls or for restraint are attached. It specifies essential dimensions, materials to be used, requirements with respect to the load-bearing capacity, of the roof safety hooks fast
22、ened to the roof construction including their fastening system and the extent of testing. This document does not apply to installations which are used exclusively as anchorage points to which personal protective equipment against falls or for restraint are attached (see EN 795). 2 Normative referenc

27、lanyard EN 517:2006 (E) 5 P test load 5 Materials Roof safety hooks and their fastening systems shall be of metal and be resistant to corrosion as well as to atmospheric and climatic influences. The material shall be free from faults and inclusions which may impair their performance abilities. The c
28、orrosion resistance shall be at least equivalent to that of hot-galvanized steel with a protective layer of 50 m as in EN ISO 1461. Parts of the fastening system beneath the roof covering may be from timber and shall then be protected against atmospheric and climatic influences. 6 Dimensions and con
29、struction requirements 6.1 General Roof safety hooks are installations for creating higher workplaces by securing a slaters ladder or by attaching working platforms. They can simultaneously be used as anchorage points for personal protective equipment against fall or for restraint. The type and size
30、 of the fastening system shall be specified by the manufacturer. 6.2 Roof safety hooks Roof safety hooks are differentiated as follows (see Figure 1): Type A: Roof safety hooks designed to accept tensile forces in the direction of the slope of the roof (y-axis). Type B: Roof safety hooks designed to
31、 accept tensile forces in the direction of the slope of the roof (y-axis), in the opposite direction (y-axis) as well as in the perpendicular direction and parallel to the roof surface (x-axis). Roof safety hooks shall have an opening of not less than 80 mm and not more than 150 mm, see Figure 2. Th
32、e height h of the hook shall be at least 120 mm. A closed loop with an opening of at least 20 mm 40 mm, e.g. a closed eyelet welded on (see Figure 2), to which personal protective equipment against falls or for restraint may be attached, shall be fitted to the hook base. Where roof safety hooks are
33、fastened by nails to the load-bearing roof construction, at least three radially grooved nails (6,0 mm x 80 mm or 5,0 mm x 70 mm) shall be used. The load-bearing capacity of all fastener systems shall be proved by testing according to Clause 7. EN 517:2006 (E) 6 Key 1 Type A 2 Type B Figure 1 Roof s
34、afety hooks, types Dimensions in millimetres Key 1 Fastening system 2 Hook base 3 Loop Figure 2 Roof safety hook (example) 7 Requirements 7.1 Static load in the hook base Roof safety hooks including their fastenings shall be designed for a single load of Fv 1,5 kN in the direction of the y-axis in t
35、he hook base, see Figure 2. Compliance with the requirements shall either be proved by means of a static calculation or, if this is not possible, the product shall be tested according to 8.1.2. NOTE For further calculations see ENV 1993 and ENV 1999. EN 517:2006 (E) 7 Under this load the distortion
36、shall not be more than 5 mm in the direction of the y-axis. The deflections and deviations shall be measured relative to the load-bearing roof construction. 7.2 Static load in the anchorage point Roof safety hooks of Type A including their fastenings shall be designed to accept a single static load
37、at the anchorage point of Fy2= 10 kN in the direction of the y-axis. Roof safety hooks of Type B including their fastenings shall be designed to accept a single static load at the anchorage point of Fy= 10 kN in the direction of the y-axis (both directions) as well as a single static load of Ft2= 10
38、 kN in the direction of the x-axis. Compliance with the requirements shall either be proved by means of a static calculation or, if this is not possible, the product shall be tested according to 8.1.3. The indicated single loads are test loads which shall at least be specified. NOTE For further calc
39、ulations see ENV 1993 and ENV 1999. The roof safety hooks and their fastenings shall not fail under the single loads as indicated, the single loads shall be held safely. 7.3 Fatigue strength Roof safety hooks including their fastenings shall be designed to withstand the dynamic load of the test acco
40、rding to 8.2 at any point where it is possible to attach personal protective equipment against fall or for restraint (anchorage point). 7.4 Reaction to fire and external fire performance Installations (safety hooks) covered by this document are reaction to fire Class A1 without the need for testing1
41、)and are deemed to satisfy external fire performance requirements2). 8 Testing 8.1 Static load 8.1.1 Number of specimens Each test shall be made once each on three different specimens. All specimens shall pass the tests. 8.1.2 Test in the hook base The specimens (roof safety hooks) shall be fastened
42、 to the simulation of the load-bearing roof construction according to the instructions of the manufacturer. The test load of 1,5 kN shall be applied within one minute and maintained for a period of five minutes. 1) See Commission Decision 96/603/EC as amended by Commission Decision 2000/605/EC. 2) S
43、ee Commission Decision 2000/553/EC. EN 517:2006 (E) 8 The deformation shall be measured under the test load of 1,5 kN and shall not deflect more than 5 mm in direction of the force. The test load is then increased to 1,5 kN x 1,7 kN = 2,6 kN for a further minute. In case of the maximum load of 2,6 k
44、N the functioning of the specimen and its fastening shall not be impaired. NOTE The value of 1,7 is a safety factor. 8.1.3 Test at the anchorage point Apply a static test load of Fy2= 10 kN to the anchorage point for protective equipment against falls or for restraint in the direction of use (direct
45、ion of y-axis) for roof safety hooks. Apply an additional static test load of Fy2= 10 kN in the direction of the negative y-axis and in the direction of the x-axis for roof safety hooks of Type B. The test loads in the y-direction and x-direction are applied to different specimens. Neither the roof
46、safety hook nor the fastening shall become loose, and the test load shall be held safely. 8.2 Test of fatigue strength Roof safety hooks shall additionally be tested in accordance with the requirements of 7.3. Three test specimens shall be submitted to a drop test (see Figure 3). The test specimens
47、shall be fixed by their fastening systems to a simulation of the load-bearing roof construction in a position between 70 and 90 from the horizontal. The load and deflection criteria of the drop test shall conform to EN 364. For the test, a hawser laid polyamide lanyard of three strands and of 12 mm
48、diameter according to EN ISO 1140 shall be used.

EN 517:2006 (E) 10 One end of the lanyard shall be attached to the anchorage point of the test specimen. At the other end of the lanyard a drop mass of (100 1) kg and (200 2) mm in diameter shall be fastened. The drop mass shall be suspended at a maximum horizontal distance of 300 mm from the anchorage point of the lanyard and a vertical distance of 500 mm from that point by means of a
