26、4 General In the testing of safety devices, all related parts associated with the protection from strangulation shall be included. BS EN 16434:2014EN 16434:2014 (E) 5 For example, a breakaway device for an operating ball-chain should cover the ball-chain and the connector if the connector is depende

27、nt on the ball diameter. If an inner cord breakaway device is dependent on the type of fabric used in the internal blind then the fabric should also be considered as a part of the safety device. The number of samples tested shall be representative of the production run. Testing shall be repeated dur

28、ing the production to ensure that performances of devices are maintained. Testing shall be repeated whenever a change occurs in the design, in the composition, in the raw material or in the supplier of the raw material, or in the method of production. NOTE Guidance on sampling procedures can be foun

29、d in ISO 2859-1. Although weights are used in the figures illustrating test methods, any other mechanical, hydraulic or pneumatic equipment may be used. All weights and forces shall be applied with a tolerance of 1 %. Unless specified otherwise, all tests defined in this standard shall be performed

30、at 23 C 5 C. Annex A presents a summary of the tests to be carried out on safety devices. In the context of this standard, the term “cord(s)” used shall mean “cord(s), chain(s), ball-chain(s), tape(s) and similar”. 5 Artificial ageing 5.1 Exposure to UV Before testing the safety devices, they shall

31、be subjected to the cycle N6 according to EN ISO 4892-2 or the cycle N5 according to EN ISO 4892-3 for 500 h. 5.2 Mechanical endurance The mechanical endurance test is intended to reproduce the operating cycles of internal blinds. Before testing the safety devices, they shall be submitted to the fol

32、lowing endurance test: a mechanical endurance test shall be carried out either according to EN 14201 on a representative internal blind or using a mechanical test equipment reproducing the load conditions of the representative internal blind. 5 000 cycles of extension/retraction shall be considered.

33、 The internal blind considered for the test shall be the maximum size for which the safety device is intended. 5.3 Effect of temperature Before testing the safety devices, they shall be submitted to the following temperature conditions: Low temperature: the safety devices shall be submitted to condi

34、tioning at an air temperature of 5 C 3 C for a minimum of 4 h. High temperature: the safety devices shall be submitted to conditioning at an air temperature of 60 C 3 C for a minimum of 4 h. The relevant tests of Clauses 6 to 11 shall then start at 23 C 5 C within 15 min. 6 Tensioning device 6.1 Gen

35、eral This clause applies to safety devices intended to maintain continuous cord(s) forming a loop under tension and secured to a fixed surface (e.g. window frame, wall). BS EN 16434:2014EN 16434:2014 (E) 6 The test shall be carried out on the smallest and the largest diameter of cord(s) for which th

36、e tensioning device is designed. The test shall be carried out on sample(s) as defined in Clause 4: in their original condition, that have been exposed to UV as specified in 5.1, that have been subjected to the mechanical endurance test as specified in 5.2, that have been subjected to the effect of

37、temperature as specified in 5.3 (at low temperature and at high temperature). Where a tensioning device is designed to accept more than one cord, each cord shall be tested separately. It shall be verified that the fixed retaining device maintaining the cord(s) under tension shall not crack or fractu

38、re under the application of a horizontal load applied in the middle of the cord. In addition, it shall be verified that the cord is retained within the device when the device is fixed 10 mm higher than its intended position. The control mechanism shall be made of a pulley of 50 mm diameter. The leng

39、th of the pull cord shall be 1 m (see Figure 1). Key 1 pull cord(s) 2 pulley 3 retaining device Figure 1 Principle of the test of tensioning device BS EN 16434:2014EN 16434:2014 (E) 7 6.2 Test methods 6.2.1 Resistance of the retaining device The tensioning device shall be installed according to the

40、installation instructions of the manufacturer. The retaining device shall be installed at the maximum distance possible from the pulley (original position). The distance between the two strands of the loop shall be measured at the point of exit from the tensioning device (see Figure 2). Key 1 distan

41、ce between the two strands Figure 2 Measurement of the distance between the two strands A horizontal force shall be applied in the plane and at mid-point of the height of the loop (see Figure 1) in a progressive way over a period of maximum 5 s until the load defined in 6.3 is applied to one cord. T

42、he load shall be then maintained for 10 s. The test shall be carried out with the load defined in 6.3. The test shall be repeated with the force being applied in the direction perpendicular to the plane of the cord. 6.2.2 Retention of cords The retaining device shall be installed at 10 mm above its

43、original position (see 6.2.1). The cord shall then be pulled with the force defined in 6.3 in all possible directions. BS EN 16434:2014EN 16434:2014 (E) 8 6.3 Requirements The distance between the two strands of the loop shall be less than 50 mm at the point of exit from the tensioning device. When

44、tested according to 6.2.1, no part of the fixed tensioning device shall crack or fracture under the application of a load of 60 N to the pull cord(s). The fixed tensioning device shall continue to function as intended. When tested according to 6.2.2, the cord shall remain in the retaining device whe

45、n pulled with a force of 60 N in all possible directions. 7 Breakaway device 7.1 General This clause applies to device(s) intended to connect: Case N1: two ends of the same cord, Case N2: several cords together at any point below the headrail, or Case N3: a cord to a curtain, and to break away under

46、 the application of a load. As these devices are made of minimum two parts that separate under a specific load, all these parts shall be considered during the tests. As a consequence, these devices shall be considered as a whole and cannot be used separately. This test shall be carried out on sample

47、(s) as defined in Clause 4: in their original condition, that have been exposed to UV as specified in 5.1, that have been subjected to the following mechanical endurance test: The breakaway element shall be engaged and disengaged 20 times at a maximum of 3 min intervals, to ensure that the reengagem

48、ent of the element is still possible. Engagement and disengagement may be carried out manually. that have been subjected to the effect of temperature as specified in 5.3 (at low temperature and at high temperature). 7.2 Test method The safety device shall be installed according to the installation i

49、nstructions of the manufacturer. In the case N1 of 7.1, the two ends of the pull cord shall be permanently secured to the test rig 60 mm apart. The length of the loop shall be at least 500 mm. The test shall be carried out on the breakaway device, so that each breaking point is successively located at the highest possible position, at the lowest position (at the bottom of the loop) and in the middle of the loop (see Figure 3).
