17、gdom. BS EN 16433:2014EN 16433:2014 (E) 4 1 Scope This European Standard specifies test methods for the verification of the requirements relating to the protection from strangulation. This European Standard applies to all internal blinds as specified in EN 13120, insect screens as specified in EN 13
18、561 and to blinds in sealed glazed units. These products may be operated manually, with or without compensating springs, or by means of electric motors (power operated products). Although at the time this standard has been published, no product standard exists for draperies, test methods specified i
19、n the present standard may be used for such products. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

All dimensions, masses a
24、nd forces shall be considered with a maximum tolerance of 1 %. Although all figures show free-hanging loads to apply forces, other methods of achieving the same effect may be used. Unless otherwise specified, a pulley of 20 mm diameter shall be used to apply the loads. Annex A presents a flowchart s
25、ummarizing tests to be carried out on internal blinds. The internal blinds shall be installed according to the manufacturer specification so that the installation, i.e. the test rig, the fixing, etc., has no influence on the results of tests. In the context of this standard, the term “cord(s)” used
26、shall mean “cord(s), chain(s), ball-chain(s), tape(s) and similar”. The head probe shall have the dimensions and design specified in Figure 2. It shall be made of a rigid material and shall have a smooth finish. NOTE This probe is taken from ANSI/WCMA A100.12010 and is equivalent to the small head p
27、robe defined in CEN/TR 13387:2004 (Table 3.3B) for children aged from 9 to 12 months.

28、 7 5 Test sample A test sample shall be representative of a family of products which may cover a variety of dimensions or weight of internal blinds. In the context of this standard, a family of products is defined with regard to the utilization of common safety device(s) and any design aspect relati
29、ng to protection from strangulation. Within a family, the test sample shall be chosen so that the following conditions are fulfilled: Tensioning systems: this test shall be carried out on an internal blind with the maximum length of the operating cord(s). Breakaway systems: the tests shall be carrie
30、d out on an internal blind taking into account the maximum number of pull cord(s). Accumulation systems: the tests shall be carried out on an internal blind taking into account the maximum length and number of pull cord(s) when the curtain is retracted. Inner cord(s): the tests shall be carried out
31、on an internal blind taking into account the maximum distance between two consecutive points of attachment / retention. Within a family of products, there is no variation in the design of the internal blind that would affect the tangling test. 6 Breakaway system 6.1 General For the tests defined in
32、6.2 a test cylinder of 60 mm diameter made of a rigid material shall be inserted into the loop. The total mass specified in EN 13120 shall be gradually applied downwards. This mass shall include the mass of the cylinder. “Gradually” means there shall be no dynamic effect on the cord. NOTE The test c
33、ylinder is intended to represent the neck of a child. 6.2 Test method 6.2.1 Operating system consisting of a pull cord(s) forming a hazardous loop The length of the pull cord(s) shall be measured. The test shall be carried out on the breakaway system so that a breakaway device is successively locate
34、d at the highest possible position, at the lowest position (at the bottom of the loop) and in the middle of the loop (see Figure 4). After a successful breakaway test, the affected device shall be replaced. If several breakaway devices are used, they all shall be tested in the positions mentioned ab
35、ove.

36、pecific component (e.g. a breakaway device), the test shall be carried out with the loop in any position. 6.2.2 Operating system consisting of free hanging pull cord(s) connected together The length of the pull cord(s) shall be measured. The internal blind shall be placed in the fully retracted posi
37、tion (see Figure 5). If more than two cords are connected together, all possible loop combinations shall be tested.

40、p and maintained under tension by a system secured to a fixed surface (e.g. window frame, wall, .). It shall be verified that the tensioning system consisting of the pull cord(s), the control mechanism: the pulley and its housing, and the fixed retaining device maintaining the cord(s) under tension,
41、 shall not break under the application of a horizontal load applied in the middle of the cord(s) (see Figure 7). Where a tensioning system is designed to accept more than one cord, each cord shall be tested separately. BS EN 16433:2014EN 16433:2014 (E) 11 Key 1 pull cord(s) 2 control mechanism 3 fix
42、ed retaining device Figure 7 Principle of the test of tensioning system 7.2 Test method All installation positions described in the installation instructions of the manufacturer shall be tested. The distance between the two strands of the loop shall be measured at the point of exit from the fixed te
43、nsioning system (see Figure 8). BS EN 16433:2014EN 16433:2014 (E) 12 Key 1 distance between the two strands Figure 8 Measurement of the distance between the two strands The length of the pull cord(s) shall be measured. A horizontal force shall be gradually applied in the plane and at mid-point of th
44、e height of the loop (see Figure 7) until the load defined in EN 13120 is applied to the cord. Gradually means there shall be no dynamic effect on the cord. The load shall be then maintained for 10 s. The test shall be repeated with the force being applied in the direction perpendicular to the plane
45、 of the cord. 8 Accumulation system 8.1 General This subclause applies to internal blinds for which extension and retraction of the curtain leads to a change in length of the pull cord(s). It shall be verified that the full length of pull cord(s) can be accumulated at any position of the curtain, in
46、cluding fully retracted. 8.2 Test method The length of the pull cord(s) shall be measured when the internal blind is in the fully extended position. The pull cord(s) shall be accumulated according to the instructions of the manufacturer when the internal blind is in the fully retracted position. BS

In this situation, it shall be verified that the two cords present cannot tangle producing a hazardous loop. 9.2 Test method One
48、 cord shall be twisted around the other 5 times. This shall be carried out by rotating one cord around the other, commencing 200 mm from their respective ends towards the open end (see Figure 9). Key 1 pull cords 2 headrail Figure 9 Illustration of the tangling test The cords shall then be released.
49、 If the cords do not separate, a cylinder of 60 mm diameter shall be inserted into the loop. The mass defined in EN 13120 shall be gradually applied to the cord. Gradually means there shall be no dynamic effect on the cord. This mass shall include the mass of the cylinder. This test shall be carried out with the ends of the cords being at the same level. It shall be repeated 5 times. 10 Inner cords 10.1 General It shall be verified whether inner cords are accessible. If accessible, it shall be determined whether a hazardous loop is pres
