28、02 EN 926-1:2015(E)4 Introduction The EN 926 series consists of two parts: EN 926-1 details paraglider structural strength requirements and EN 926-2 details paraglider flight tests requirements. Paragliders that have been tested and found to be compliant with both EN 926-1 and EN 926-2 are therefore

29、 compliant with the EN 926 series. The aim of these standards is to enhance safety thus eliminating paragliders which display unacceptable behaviour in given situations on the basis of recognized tests set in these two standards. DIN EN 926-1:2016-02 EN 926-1:2015(E)5 1 Scope This European Standard

30、is applicable to paragliders as defined in 2.1. This part of EN 926 specifies requirements and test methods for the resistance of a paraglider to static and dynamic loads and sets the minimum strength threshold for its qualification. 2 Terms and definitions For the purposes of this document, the fol

31、lowing terms and definitions apply. 2.1 paraglider ultra-light glider with no primary rigid structure, for which take-off and landing are on foot, with the pilot (and potentially one passenger) carried in a harness (or harnesses) connected to the wing 2.2 model of paraglider paragliders of different

32、 sizes of a given design are considered to be the same model when fulfilling the following criteria: a) the different sizes have been obtained by using a uniform scale factor; b) for all sizes identical materials are used; c) the way materials are processed is identical for all sizes 2.3 identically

33、 constructed lines lines where the only elements that differ are the finished line length and/or cosmetic colour 2.4 main control lines entire line systems that terminate at the two primary control handles 2.5 significant damage rupture of any of main load bearing component of the structure 3 Requir

34、ements 3.1 Shock loading When tested according to 4.4, a visual inspection of the wing shall not show significant damage. 3.2 Sustained loading When tested according to 4.5 the wing shall sustain 4.5.2. 1) or 4.5.2 2). 3.3 Breaking strength of the suspension lines The lines shall be tested according

35、 to 4.6. If identically constructed lines have already been tested, then the result may be used. The minimum breaking strength of any line shall be greater than 200 N. The first level is defined as the lines attached to the risers. DINEN 926-1:2016-02EN 926-1:2015 (E) 6 The sum of strength after ben

36、ding test of the lines of the first level shall exceed the greater of 14 g max weight in flight or 14 000 N (g = 9,81 m/s2). For each level the same calculation is performed. The result shall exceed the greater of 14 g max weight in flight or 14 000 N (g = 9,81 m/s2). Subsequent levels (as shown in

37、Figure 1) are defined by each further line junction. If a line is directly attached to the wing (i.e. no line junction above it), its strength shall also be used during the calculation of the strength of each of the level(s) above it. An example calculation is given in Annex A. Key 1 Wing 2 Risers L

38、1 Level 1 L2 Level 2 L3 Level 3 L4 Level 4 Figure 1 Example of line rigging 3.4 Breaking strength of the main control lines The lines shall be tested according to 4.6. If identically constructed lines have already been tested, then the result may be used. The sum of the strength of the lines of each

39、 level shall exceed 1 500 N (i.e. 2 750 N). The minimum breaking strength of any line shall be greater than 200 N. The first level is defined as the lines attached to the main control handle(s) including the control handle and the attachment of the line to the handle. DIN EN 926-1:2016-02 EN 926-1:2

40、015(E)7 When a control handle is connected to a control line in the manner described in the user manual, the connection between the control handle and the first level of line shall have a minimum breaking strength of 750 N. 4 Test methods 4.1 Apparatus 4.1.1 Weak link The weak link shall be chosen f

41、or instantaneous break at a load defined in Table 1 according to the total weight in flight: Table 1 Selection of weak link break loads Total weight in flight (kg) 120 120 to 180 180 to 240 240 Break load of the weak link (N) 8 000 10 000 12 000 14 000 The use of weak links with a tolerance of 5% is

42、 allowed. Weak links shall be protected against torsional load as recommended by the manufacturer. For each additional 60 kg value above 240 kg total weight in flight, the break load of the weak link shall be increased by 2 000 N. Where individual weak links of the specified values are not available

43、, it is permissible to pair in parallel two identical weak links of half of the required value. 4.1.2 Cable The shock test cable shall meet the following requirements: length: 125 m (1%); minimum breaking strength: 50 kN; the elastic elongation at 5 kN shall be between 11,8 cm and 14,4 cm. NOTE The

44、elastic elongation is equal to 1,05 per thousand ( 10 %) at 5 kN . 4.1.3 Electronic sensor An electronic sensor equipped with an electronic strain gauge for measuring the force (sampling a minimum of 10 times per second) is required for 4.5. 4.1.4 Measurement circuit With a graph clearly showing the

45、 load (N) against time (s). 4.1.5 Video recording equipment Video recording equipment shall be used to record the overall behaviour of the glider during the tests. More than one camera may be used. . DIN EN 926-1:2016-02 EN 926-1:2015 (E) 8 4.1.6 Test vehicle For the shock load test, a vehicle with

46、a verified means of indicating ground speed to within 1 km/h, shall be used. 4.2 Test specimen Select one test specimen that conforms to the manufacturing record for that model. This specimen is used for both for test 4.4 and test 4.5, first 4.4 and then 4.5. No changes to the specimen shall be made

47、 between the two tests. Either: a) every size of a particular paraglider design shall separately be tested or; b) where different sizes meet the criteria of being the same model, then the size with the largest maximum total weight in flight is tested. In this case, the maximum total weight in flight

48、 for all the smaller sizes shall not exceed: 9,0glidertestedmaxmax=WW 4.3 Test conditions For the shock loading test in 4.4, the wind speed in the immediate vicinity of the glider shall be less than 4m/s. 4.4 Shock loading test 4.4.1 Principle The paraglider is subjected to a shock load and the wing

49、 is then visually inspected for significant damage. 4.4.2 Procedure Carry out the shock loading test using a weak link to limit the loads to a maximum force according to Table 1. Place the paraglider vertically such that it is supported from close to the leading edge with the trailing edge in the centre touching the ground and the span fully extended. The number of supports shall be at least equal to the number of
