These normative references are cited at the appr
24、opriate 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. For undated references the latest edition of the publi
25、cation referred to applies. prEN 1253-1:1997, Gullies for buildings Part 1: Requirements. prEN 1253-4, Gullies for buildings Part 4: Access covers. 3 Definitions For the purposes of this standard, the following definitions apply. 3.1 clear opening diameter of the largest circle that can be inscribed
26、 in the clear area of the frame 3.2 test load specified load which a component is required to withstand when tested in accordance with clause 4 4 Loading test 4.1 Test loads and permanent set The values given in Table 1 shall be applied. No crack or fracture shall occur before the test load has been
27、 attained. In addition, in the case of gullies with a grating or a cover made of ductile cast iron, steel, non-ferrous metals, plastics or these materials in combination with concrete, the permanent set shall not exceed the values given in Table 1. Table 1 Test loads and permanent set ClassTest load
28、 P kN Permanent set f at 2/3 P H 1,51,5 K 332/500 (0,4 %) of the clear opening (CO) but not more than 2,0 mm L 1515 M 125125 For gratings in accordance with prEN 1253-1:1997, 5.2, a test load P of 0,25 kN shall be applied and the permanent set f at 2/3 of the test load shall not exceed 2,0 mm. 4.2 T
29、esting machine The testing machine, preferably a hydraulic press, shall be capable of applying a load of at least 25 % greater than the test loads. The dimensions of the bed of the testing machine shall be greater than the bearing area of the unit to be tested. The testing machine shall be capable o
30、f applying and maintaining the test load within a tolerance of3 %. 4.3 Test blocks The shape and dimensions of frames and corresponding test blocks are given in Table 2. An intermediate layer of a thin coating of gypsum, cardboard, rubber or similar shall be applied between the grating or cover and
31、the test block. Bottom edges of the test block shall be rounded with a radius # 3 mm. When testing gratings or covers with a non-flat surface, the contact face of the test block shall be shaped to match the grating or cover. 4.4 Procedure Place the gully according to the manufacturers installation i
32、nstructions in a special test support (concrete, frame, wood etc.) on the bed of the testing machine. Apply the test load, by means of the specified test block, vertically to the centre of the grating or cover. When different versions of the same component exist, testing shall be applied to the most
33、 unfavourable of their combinations. Before the load is applied, locate the geometric centre of the cover or grating and ensure this point has a smooth surface and take a datum reading at this point measured to an accuracy of0,1 mm. For gratings/covers made of cast iron or of this material in combin
34、ation with concrete, the load shall be steadily increased with the prescribed load being attained within 1 min. Check that no crack or fracture has occured. For gratings/covers made of ductile cast iron, of steel, non-ferrous materials, plastics or these materials in combination with concrete the lo
35、ad shall be applied at a rate of 1 kN/s to 5 kN/s up to 2/3 of the test load; the load on the test specimen is then released. This procedure shall be carried out five times. After 1 h take a new reading at the geometric centre of the cover or grating. The permanent set shall then be determined as th
36、e difference between the two readings and the set shall not exceed the values given in Table 1. The loading shall then be steadily increased, with the prescribed test load being reached within 1 min and maintained for 5 min. Check that no crack or fracture has occured. Testing shall be carried out a
37、t ambient temperature on three gratings/covers, each of which shall meet the requirements.

39、here is just so much water in the seal that through movement of air can take place without movement of the water surface. 5.2 Resistance of water seal to pressure Mount the gully in a test arrangement illustrated in Figure 1, and fill the trap with water. Close the flap and set a negative pressure o
40、f 400 Pa by means of the bypass valves. Open the flap and fill the trap with water. Close the flap and slowly open after about 5 s. Repeat this procedure until the trap no longer loses water, but no more than 5 times. Remove 8 mm of water height; this corresponds to the reduction in the depth of wat
41、er seal due to evaporation over a period of disuse. Subject the trap on the outlet side to a positive pressure such that through flow of air just occurs. Record the pressure. With the flap closed, set the desired negative pressure P with the bypass valves, and read the manometer. The sensors in the
42、trap are connected to the printout apparatus. When the flap is closed rapidly, the desired vacuum pressure is established suddenly. By reversing the fan and securing the flap in the closed position, the arrangement can be used also for the measurement of the resistance to positive pressure. Licensed

45、pecified in prEN 1253-1:1997, 8.5. 7 Blockage prevention trapped gullies 7.1 Access for cleaning Demount and remount those parts of the gully which are designed for cleaning access to the gully itself and/or to the pipework to which it is connected. Measure and check for compliance with the requirem
46、ents of prEN 1253-1:1997, 8.6.1. 7.2 Self-cleansing capacity Using the same test arrangement described in clause 9, mount the gully including the grating. Supply cold water at (1510) 8C at a rate of 0,2, 0,3, 0,4 and 0,6 l/s to the test box. At each of the water flow rates, supply the gully through
47、the grating with 200 cm3of glass beads of (50,5) mm diameter and density 2,5 to 3,0 g/cm3. Supply the beads at a steady and uniform rate for 30 s. Continue the flow of water for a further 30 s. Measure, in cm3, the volume of glass beads that has passed through the gully. Conduct the test three times
48、 at each discharge rate. The average of the three results shall be taken. 7.3 Anti-blockage Pass a ball of 8 mm diameter through the gully with grating/cover removed from inlet to outlet merely by tilting the gully in the appropriate directions, no other force being applied to the ball. 8 Position o
49、f side inlets Close the side inlet(s) and fill the trap with water. Check whether the lowest connecting point of side inlet(s) is completely above the water level (see Figure 2). 9 Thermal behaviour 9.1 Temperature cycling for floor gullies 9.1.1 General Mount the gully in accordance with Figure 3. Connect a suitable pipe to the outlet of the gully (the outlet shall be open all the time). When different versions of the same components exist, testing shall be applied to the most unfavourable of the
