25、ction manual (guidance) in accordance with EN 1263-1:2014, Clause 9 shall be included with each consignment of safety net. This instruction manual shall be available in the language of the user. It shall contain at least the following information: required anchorage forces; maximum fall height; mini
26、mum catching width; safety net linkage; minimum distance below the safety net; storage; examination; replacement. In addition to these instructions, special installation instructions shall be followed according to the specific application of the net. 4.2 Fall height The fall heights Hi, Heand Hrare
27、defined in Table 1. DIN EN 1263-2:2015-03 EN 1263-2:2014 (E) 5 Table 1 Definitions of fall heights Figure Definition Comment Hi1 The vertical distance between the working level being safeguarded and the safety net The maximum permissible fall height into a safety net is 6 m from the working level, w
28、hich means that the maximum nominal fall height from the centre of gravity of a person is 7 m. He1, 2 and 5 The vertical distance between the edge of a working level being safeguarded and the safety net This dimension is to be used to calculate the horizontal projection of the safety net beyond the
29、working level above it. See Table 2. Hr1 The vertical distance between the working level being safeguarded and the 2 m wide border edge of the safety net. Safety nets are less able to carry an impact load near the edges of the net. Therefore, the vertical distance at this point shall not exceed 3,0
30、m. Safety nets should be erected as close as possible below the working level. Each of the fall heights Hiand Heshall not exceed 6,0 m (see Figure 1, Figure 2 and Figure 5). In addition to this, the reduced fall height Hrwithin 2 m of the border shall not exceed 3,0 m (see Figure 1). 4.3 Catching wi
31、dth The catching width b is the horizontal distance between the edge of the working area and the edge of the safety net (see Figure 1 and Figure 2). Dependent on the fall height, the catching width b of the safety net shall not be less than the values given in Table 2. Table 2 Fall heights and requi

For rectangular
35、 safety nets the length of the shortest side shall be at least 5,0 m. Small safety nets (less than 35 m2and 5,0 m on the shortest side) are not part of this standard and should be determined by national regulations where applicable. 5.2 Positioning fixings System S safety nets shall be positioned wi
36、th tie ropes or other devices on anchorage points capable of bearing the characteristic load. For attachment devices other than tie ropes a safety factor of 2 shall be used. The distance between the anchorage points shall be less than 2,5 m. To calculate each anchorage point, the characteristic load
37、 P used shall be at least 6 kN with the fall height being 6,0 m. The assumed angle of this load shall be = 45 (see Figure 3). For the calculation of the supporting framework only three characteristic loads of 4 kN, 6 kN and 4 kN shall be considered applied in the most unfavourable way (see Figure 3)

The linkage shall be made in such a way that gaps greater than 100 m
39、m do not develop between the edges of the nets. When system S safety nets are linked by overlapping, the minimum overlap shall be at least 2,0 m. 5.4 Deformation of the safety net The maximum deformation of the safety net when rigged according to the test conditions given in EN 1263-1:2014, Clause 7
40、, is shown in Figure 4. NOTE Safety distances below the deformed safety net are not covered by this European Standard.
