DIN EN 15570:2008-08 EN 15570:2008 (E) 4 Introduction The aim of this European Standard is to provide furniture manufacturers, designers and developers with comparable information regarding the performance of all types of hinges pivo
20、ting on a vertical axis and their components. DIN EN 15570:2008-08 EN 15570:2008 (E) 5 1 Scope This European Standard specifies test methods and requirements for the strength and durability of all types of hinges pivoting on a vertical axis and their components for all fields of application. The tes
21、ts consist of the application of loads, forces and velocities simulating normal functional use, as well as misuse, that might reasonably be expected to occur. With the exception of the corrosion test in Clause 6.4, the tests are designed to evaluate properties without regard to materials, design/con
22、struction or manufacturing processes. The strength and durability tests only relate to the hinges and the parts used for the attachment, e.g. mounting plates and screws. The strength and durability tests are carried out in a test frame with specified properties. The test results can only be used as
23、a guide to the performance of a piece of furniture. The test results are only valid for the hinges tested. These results may be used to represent the performance of production models provided that the tested model is representative of the production model. With the exception of corrosion, ageing and
24、 the influence of heat and humidity are not included. Annex A (normative): Requirements for product information. Annex B (normative): Loads and cycles. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edi
25、tion cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. EN 320:1993, Fibreboards - Determination of resistance to axial withdrawal of screws EN 323:1993, Wood-based panels - Determination of density EN ISO 6270-2, Paints and varni
26、shes - Determination of resistance to humidity - Part 2: Procedure for exposing test specimens in condensation-water atmospheres (ISO 6270-2:2005) 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 catch device device that keeps or pulls a door
27、in place, but does not require a second action in order to release it, e.g. a magnetic catch or a self-closing or self-opening mechanism 3.2 damper mechanism which stops the movement of a door gently DIN EN 15570:2008-08 EN 15570:2008 (E) 6 4 General test conditions 4.1 Preliminary preparation The h
28、inges shall be assembled/mounted/adjusted according to the instructions supplied with it. If mounting, assembly or adjustment instructions are not supplied, the most adverse configuration shall be used and the mounting or assembly method shall be recorded in the test report. Fittings shall be tighte
29、ned before testing and shall not be re-tightened unless specifically required in the manufacturers instructions. If the configuration must be changed to produce the worst-case conditions, this shall be recorded in the test report. The tests shall be carried out in indoor ambient conditions at a temp
30、erature between 15 C and 25 C. If during a test the temperature is outside of the range of 15 Cto 25 C, the maximum and/or minimum temperature shall be recorded in the test report. Hinges which include structural hardware parts made of hygroscopic plastic materials, e.g. polyamide, shall be conditio
31、ned at (23 5) C and at a relative humidity of (50 5) % for 7 days before testing. NOTE For accelerating the conditioning process, EN ISO 1110:1997 1 may be used. In the case of designs not addressed in the test procedures, the tests shall be carried out as far as possible as described, and deviation
32、s from the test procedure recorded in the test report. Before beginning testing, visually inspect the hinges and components thoroughly. Record any defects to eliminate any assumption that they have been caused by the tests. Carry out measurements if specified. 4.2 Test equipment Unless otherwise spe
33、cified, the tests may be applied by any suitable device because results are not dependent upon the apparatus. The equipment shall not inhibit deflection of the test door, i.e. it shall be able to move so that it will allow the deflection of the test door during testing. 4.3 Application of forces The
34、 forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. Unless otherwise specified, each force shall be maintained for not less than 10 s and not more than 15 s. The forces in durability tests shall be applied at a rate to ensure that
35、 excessive heating does not occur. The forces may be replaced by masses. The relation 10 N = 1 kg shall be used for this purpose. 4.4 Tolerances Unless otherwise stated, the following tolerances are applicable: Forces: 5 % of the nominal force; Velocities: 5 % of the nominal velocity; Masses: 1 % of
36、 the nominal mass; Dimensions: 1 mm of the nominal dimension; DIN EN 15570:2008-08 EN 15570:2008 (E) 7 Angles: 2oof the nominal angle. The accuracy for the positioning of forces shall be 5 mm. 4.5 Sequence of testing The tests shall be carried out in the same sequence as the clauses are numbered in
37、this standard. If the clause sequence is not followed, the sequence shall be recorded in the test report. 4.6 Inspection and assessment of results Before and after the completion of each test, carry out the inspection as specified, after using adjustment devices, if available. Record any changes tha
38、t have taken place since the initial inspection. The inspection shall include at least the following: a) fracture of any component or joint; b) loosening of any joint intended to be rigid, which can be demonstrated by hand pressure; c) deformation or wear of any part or component such that its funct
39、ioning is impaired; d) loosening of any means of fixing components; e) any impaired function of a component or part. 5 Test apparatus 5.1 Masses Masses shall be designed so that they do not reinforce the structure or re-distribute the stresses. 5.2 Test frame The tests specified in 6.2 and 6.3 shall
40、 be carried out in a test frame (see Figure 1), which is so constructed that the deformation under the applied loads is no more than 1 mm. Hinges for wooden doors shall be mounted on particle board, 5.3, unless otherwise specified. Hinges for other materials, e.g. glass, metal or plastic shall be mo
41、unted according to the manufacturers instructions. The position of hinges and components on the door and the test frame as well as the size and weight of the door shall be as specified by the manufacturer, see Annex A. In cases where the door parameters (e.g. height, width, mass) are not specified b
42、y the manufacturer, the tests may be carried out using the standard door sizes specified in Annex B.

44、ts of hinges shall be used as follows: The first set shall be used for the first test sequence specified in 6.2. The second set shall be used for the second test sequence specified in 6.3. The third set shall be used for the corrosion test specified in 6.4. All overload and functional tests shall be
45、 carried out according to the same column (1, 2 or 3) in Annex B (normative). 6.2 Overload tests 6.2.1 Vertical static overload Load the door as shown in Figure 2 with the mass specified in Annex B. The mass shall be suspended 100 mm from the edge furthest from the hinge. Open and close the door 10
46、full cycles (back and forth) from a position 45o from fully closed to a position 10ofrom fully opened, up to a maximum of 135ofrom the fully closed position. Opening and closing can be done by hand using 3 s to 5 s for opening and 3 s to 5 s for closing. Carry out inspection and assessment according
47、 to 4.6 without the test load. The door and/or hinges shall not become detached.
