15、 by December 2013, and conflicting national standards shall be withdrawn at the latest by December 2013. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN and/or CENELEC shall not be held responsible for identifying any or all s
16、uch patent rights.

BS EN 16337:2013EN 16337:2013 (E) 4 1 Scope This European Standard s
18、pecifies test methods for the verification of the loading capacity of shelf supports. This standard does not apply to ceiling attached shelf support systems. The tests consist of the application of vertical loads and forces simulating normal functional use, as well as misuse that might reasonably be
19、 expected to occur. With the exception of the corrosion test in 6.4, the tests are designed to evaluate properties without regard to materials, design/construction or manufacturing processes. The strength tests include only the shelf supports and their components as well as the attachment to the cab
20、inet and/or to the wall. If the shelf support has additional functions, e.g. as a connector or as an extension element, these are not covered by this standard. The test results are only valid for the shelf supports tested. The results may be used to represent the performance of production models pro
21、vided that the tested model is representative of the production model. The test results can only be used as a guide to the performance of the shelf supports. With the exception of the corrosion test, ageing and influences of temperature and humidity are not included. Annex A (normative) includes req
22、uirements for product information. Annex B (normative) includes test parameters. Annex C (informative) includes 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 indispensable for
23、 its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

26、ass in kg, for one shelf support as specified by the manufacturer for which the shelf support will fulfil the strength requirements specified in this standard 4 General test condition 4.1 Preliminary preparation The shelf supports shall be mounted/assembled according to the instructions supplied wit
27、h them. The most adverse configuration shall be used and the mounting/assembly method shall be recorded in the test report. In case of wall mounted shelf supports more than one shelf may shall be mounted and tested. Any fixing of the shelf supports to the test wall shall be such that its strength do
28、es not influence the test result. 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 specifically
29、 required in the manufacturers instructions. If the configuration shall 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 temperature between 15 C and 25 C. If during a test the temperature is
30、outside of the range of 15 C to 25 C, the maximum and/or minimum temperature shall be recorded in the test report. Shelf supports 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
31、least 7 days before testing. Before beginning the testing, visually inspect the shelf supports 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 4.2.1 Test wall A rigid and flat surface constructed
32、in a way that the deformation under the applied load is no more than 1 mm. 4.2.2 Particle board properties The properties of the particle board shall be as specified in Table 1.

34、3 mm thick layer of rubber with hardness of (85 10) IRHD according to ISO 7619-2: a 2,5 kg impact plate, 200 mm 160 mm 10 mm; a 1,7 kg impact plate, 200 mm 109 mm 10 mm. 4.2.5 Masses Masses shall be designed so that they do not reinforce the structure or re-distribute the stresses. NOTE Steel masses
35、 with a length of 85 mm, a width of 50 mm, a thickness of 30 mm and a mass of 1 kg are suitable. 4.3 Tolerances (allowed variation from the nominal values) Unless otherwise stated, the following tolerances are applicable to the test equipment: Forces: 5 % of the nominal force; Masses: 1 % of the nom
36、inal mass; Dimensions: 1 mm of the nominal dimension; Angles: 0,2 of the nominal angle. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the above tolerances are met. 5 Test set-up The test set-up shall be as follows: a) the test set-up
37、(except shelves) shall be constructed so that the deformation under the applied loads is no more than 1 mm; b) for cabinet mounted shelf supports the sides for wooden materials (Figure 1, Pos. 3) shall be 19 mm reference particle board (see Table 1) with a depth of 600 mm (test shelf A) or 300 mm (t
38、est shelf B); the sides for other materials, e.g. glass, metal or plastic shall be as specified by the manufacturer; the clear distance between the sides shall be 1 000 mm, unless otherwise specified; the centre of the shelf supports shall be positioned 37 mm from the front and rear of the sides; or
39、 for wall mounted shelf supports (see Figure 2), the test wall (4.2.1) shall be used; the distance between the shelf supports shall be as specified by the manufacturer; BS EN 16337:2013EN 16337:2013 (E) 7 c) the shelf (Figure 1, Pos. 1) shall be 19 mm melamine faced particle board (4.2.3), the depth

43、e sustained load test specified in 6.3.2 and 6.3.3; b) the second set shall be used for corrosion test specified in 6.4, if relevant. BS EN 16337:2013EN 16337:2013 (E) 8 All tests in 6.3 shall be carried out on the same sample. 6.2 Strength requirements and tests After testing, the shelf supports sh
