21、 Turkey and the United Kingdom. DINEN 16434:2014-06EN 16434:2014 (E) 4 1 Scope This European Standard specifies requirements and test methods for safety devices to be used for protection from strangulation in internal blinds as specified in EN 13120 and insect screens as specified in EN 13561. These
22、 devices might be fitted to internal blinds and insect screens at the time of manufacture or for retrofitting. This European Standard applies to any design of device including the following: tensioning devices; breakaway devices; accumulation devices; non tangling devices; inner cord stops. Although
23、 at the time this standard has been published, no product standard exists for draperies, requirements and test methods specified in the present standard may be applied to safety devices used in such products. For clarification purpose, the term “internal blinds” used in the present standard should m
24、ean “internal blinds and insect screens”. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of th

28、ciated with the protection from strangulation shall be included. DIN EN 16434:2014-06 EN 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 dependent on the ball diameter. If an inner cord breakaway device is
29、 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 during the production to ensure that performances of devices are
30、 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 found in ISO 2859-1. Although weights are used in the figures ill
31、ustrating 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 at 23 C 5 C. Annex A presents a summary of the tests to be ca
32、rried 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 be subjected to the cycle N6 according to EN ISO 4892-2 or th
33、e 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 following endurance test: a mechanical endurance test shall be c
34、arried 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. The internal blind considered for the test shall be the maxi
35、mum 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 conditioning at an air temperature of 5 C 3 C for a minimum of 4 h
36、. 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 General This clause applies to safety devices intended to mainta
37、in continuous cord(s) forming a loop under tension and secured to a fixed surface (e.g. window frame, wall). DIN EN 16434:2014-06 EN 16434:2014(E)6 The test shall be carried out on the smallest and the largest diameter of cord(s) for which the tensioning device is designed. The test shall be carried
38、 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 temperature as specified in 5.3 (at low temperature and at
39、 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 fracture under the application of a horizontal load applied in t
40、he 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 length of the pull cord shall be 1 m (see Figure 1). Key 1 pul

The reta
42、ining 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 distance between the two strands Figure 2 Measurement of the
43、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. The load shall be then maintained for 10 s. The test sha
44、ll 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 original position (see 6.2.1). The cord shall then be p
45、ulled with the force defined in 6.3 in all possible directions. DINEN 16434:2014-06EN 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 tested according to 6.2.1, no part of the fixed tens
46、ioning 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 when pulled with a force of 60 N in all possible direct
47、ions. 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 the application of a load. As these devices are mad
48、e 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(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
