20、e This European Standard specifies test methods for the verification of the loading capacity of all types of wall attachment devices for storage furniture and their components for all fields of application. It does not apply to devices intended to prevent the overturning of storage furniture. The te

21、sts consist of the application of loads and forces simulating normal functional use, as well as misuse that might reasonably be expected to occur. With the exception of the corrosion test in 6.3, the tests are designed to evaluate properties without regard to materials, design/construction or manufa

22、cturing processes. The tests can be applied to the part attached to the furniture alone or to the combination of the part attached to the furniture and the part attached to the wall. The attachment into the wall is not included. The strength tests are carried out in a test frame with specified prope

23、rties. The test results are only valid for the devices 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 the corrosion test, ageing and influences of temperature and humi

24、dity are not included. Annex A (normative) includes requirements for product information. Annex B (informative) includes a method for the determination of loading capacity. 2 Normative references !The following documents, in whole or in part, are normatively referenced in this document and are indis

30、t method for the determination of the loading capacity is described in Annex B (informative). 3.2 wall attachment device device including the component that is attached to the cabinet (e.g. suspension bracket) and the component that is attached to the wall (e.g. hook, rail) 3.3 non-commercial wall p

31、art piece of test equipment specified in 4.2.8 4 General test condition 4.1 Preliminary preparation The wall attachment device(s) shall be mounted according to the instructions supplied with them. The most adverse configuration shall be used and the mounting or assembly method shall be recorded in t

32、he test report. 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. The fixing to the wall shall be of such strength that the test result is not influenced. Fittings shall be tig

33、htened before testing and shall not be re-tightened unless specifically required in the manufacturers instructions. If the configuration is to be changed to produce the worst-case conditions, this shall be recorded in the test report. For testing a range of related wall attachment devices, only wors

34、t case(s) need to be tested. The tests shall be carried out in indoor ambient conditions 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. Wall attachment devi

35、ces which include structural hardware parts made of hygroscopic plastic materials, e.g. polyamide shall be conditioned at (23 5) C and a relative humidity of (50 5) % for at least seven days before testing. Before beginning the testing, visually inspect the wall hanging device(s) thoroughly. Record

36、any defects so that they are not assumed to have been caused by the tests. Carry out measurements when specified. 4.2 Test equipment 4.2.1 Test wall A rigid, vertical and flat surface which is so constructed that the deformation under the applied load is no more than 1 mm.
