26、a hook opening h hook height R 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 the
27、ir performance abilities. The corrosion 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 i
28、nfluences. 6 Dimensions and construction 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 f
29、or restraint. The type and size 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
30、: Roof safety hooks designed to 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 mor
31、e than 150 mm, see Figure 2. The 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 bas
32、e. Where roof safety hooks are 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
33、Type A 2 Type B Figure 1 Roof safety 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 t
34、he direction of the y-axis in the 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
35、Under this load the distortion 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
36、to accept a single static load 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
37、a single static load of Ft2= 10 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 s
38、pecified. NOTE For further calculations 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 th
39、e dynamic load of the test according 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 A
40、1 without the need for testing1)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
41、safety hooks) shall be fastened 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 Commis
42、sion Decision 2000/605/EC. 2) See 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 ca
43、se of the maximum load of 2,6 kN 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
44、in the direction of use (direction 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 differe
45、nt specimens. Neither the roof 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
46、 Figure 3). The test specimens 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
47、 of three strands and of 12 mm diameter according to EN ISO 1140 shall be used. EN 517:2006 (E) 9 Dimensions in millimetres Key 1 Rapid release 2 Roof construction 3 Lanyard 4 Drop mass 5 Anchorage point Figure 3 Dynamic test (fatigue strength) An eye of (75 10) mm size shall be spliced into each en
48、d of the lanyard with splices of 5 full tucks and equipped with karabiners. The effective length of the lanyard measured under a load of (40 5) N shall be (2 000 50) mm. 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 l
49、anyard 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 quick release device. Release the drop mass which will fall freely through (2 500 50) mm before the lanyard arrests the fall. Observe any deformations and deflections of the test specimen and its fastenings, and the test load shall be supported safely. 9 Eval
