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 locking mechanisms. NOTE Examples of typical locking mechanisms are given in CEN/TR 16015. BS EN 16014:2011E

18、N 16014:2011 (E) 4 1 Scope This European Standard specifies test methods and requirements for the strength and durability of all types of locking mechanisms for furniture and their components for all fields of application. This European Standard does not apply to latching mechanisms. The tests consi

19、st of the application of loads, forces simulating normal functional use, as well as misuse that might reasonably be expected to occur. With the exception of the corrosion test in 6.5, the tests are designed to evaluate properties without regard to materials, design/construction or manufacturing proc

20、esses. The strength and durability tests only relate to the locking mechanisms and their components and the parts used for the attachment, e.g. screws. The strength and durability tests are carried out in particle board with specified properties. The test results can only be used as a guide to the p

21、erformance of a piece of furniture. The test results are only valid for the locking mechanisms and their components 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 corr

22、osion, ageing and influences of heat and humidity is not included. Annex A (normative): Product information system. Annex B (normative): Test parameters. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the e

23、dition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

24、2:2005, Paints and varnishes 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. 3.1 locking mechanism mechanism that

25、limits access to the interior of a unit or a storage element NOTE It requires a key or a combination in order to activate it or to make it possible to activate it. ISO 7170:2005 and EN 14074:2004 BS EN 16014:2011EN 16014:2011 (E) 5 3.2 latch mechanism which retains an extension element or a door in

26、the closed position NOTE It requires a second action in order to release it. 3.3 stop part of hardware in the cabinet which works together with the locking hook CEN/TR 16015:2010, 2.5.1 4 General test conditions 4.1 Preliminary preparation The locking mechanism shall be assembled/mounted according t

27、o the instructions supplied with it. If mounting or assembly 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 tightened before testing and shall not be re-tightened unless specifica

28、lly 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. For testing a range of related locks, only worst case(s) need to be tested. The tests shall be carried out in indoor ambient condition

29、s at a temperature between 15 C and 25 C. If during a test the temperature is outside of the range of 15 C to 25 C, the maximum and/or minimum temperature shall be recorded in the test report. Locking mechanisms which include structural hardware parts made of hygroscopic plastic materials, e.g. poly

30、amide shall be conditioned at (23 5) C and a relative humidity of (50 5) % for at least 7 days before testing. If a test cannot be carried out as specified in this standard, e.g. because a loading pad cannot be used for the application of a force due to the design of a product, the test shall be car

31、ried out as far as possible as specified. Before beginning the testing, visually inspect the lock thoroughly. Record any defects so that they are not assumed to have been caused by the tests. Carry out measurements when specified. 4.2 Test equipment The equipment shall not inhibit deformation of the

32、 lock, i.e. it shall be able to move so that it can follow the deformation of the lock during testing. All loading pads shall be capable of pivoting in relation to the direction of the applied force. The pivot point shall be as close as practically possible to the load surface. 4.3 Application of fo

33、rces The 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 ens

34、ure that excessive heating does not occur. BS EN 16014:2011EN 16014:2011 (E) 6 The forces may be replaced by masses. The relation 10 N = 1 kg shall be used for this purpose. 4.4 Tolerances (allowed variation from the nominal values) Unless otherwise stated, the following tolerances are applicable to

35、 the test equipment: Forces: 5 % of the nominal force; Velocities: 5 % of the nominal velocity; Masses: 1 % of the nominal mass; Dimensions: 1 mm of the nominal dimension; Angles: 2 of the nominal angle. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversel

36、y affected when the above tolerances are met. 4.5 Test sequence The tests shall be carried out in the same sequence as the clauses are numbered in 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

37、 and after completion of each test, carry out the inspection as specified, after using adjustment devices, if available. Record any changes that have taken place since the initial inspection. The inspection shall include at least the following: a) the fracture of any component or joint; b) the loose

38、ning of any joint intended to be rigid, which can be demonstrated by hand pressure; c) the deformation or wear of any part or component such that its functioning is impaired; d) the loosening of any means of fixing components; e) any impairment of a component or part. 5 Test apparatus 5.1 Loading pa

39、d Type A: rigid cylinder with a flat face; the diameter of which shall be 2/3 of the smallest width or diameter of the lock tested; Type B: rigid cylinder, (5,0 0,1) mm diameter, with a hemispherical face; Type C: test bolt identical in shape and form to the part belonging to the locking mechanism.

40、BS EN 16014:2011EN 16014:2011 (E) 7 5.2 Test plates The tests specified in 6.2 and 6.3 shall be carried out in a test plate, which is so constructed that the deformation at the measurement points under the applied load is no more than 1 mm. The test plate shall be at least 50 mm larger than the lock

41、 to be tested. Unless otherwise specified by the manufacturer, the locks shall be mounted on a 19 mm particle board, see 5.3. 5.3 Particle board properties The properties of the particle board shall be as specified in Table 1.
