Domestic and non-domestic storage furniture - Test methods for the determination of strength, durability and stability
This European Standard specifies tests methods for the determination of strength, durability and stability for all types of domestic and non-domestic storage furniture including domestic kitchen furniture. It does not apply to office, industrial, catering equipment and retail storage, nor to industrial storage lockers. Strength and durability tests do not assess the structure of the building (for example the strength of wall hanging cabinets); rather, they include only the cabinets and the parts used for attachment. The wall and the wall attachments are not included. Requirements for safety, strength and durability can be found in other European Standards. Assessment of the effects of ageing, degradation and flammability is not included. Annex A (normative) contains details of test equipment for the slam open/shut testing of extension elements.

3.14 levelling device adjustable device intended to keep the item of furniture perpendicular to the floor
EXAMPLE Adjustable feet or similar. 4 General test conditions 4.1 Preliminary preparation The unit(s)/component(s) shall be tested as delivered. The unit(s)/component(s) shall be assembled and/or configured according to the instructions supplied. Unless otherwise stated, the most adverse configuration shall be used for each test. If mounting or assembly instructions are not supplied, 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 required in the manufacturer’s instructions. If the configuration needs to be changed in order to produce the worst-case conditions, this shall be recorded in the test report. Levelling devices shall be set as near as possible to 5 mm from the fully open position whilst ensuring the unit is perpendicular to the floor. A combination of tests may be necessary to cover the properties of multifunction components; e.g. a receding door shall be tested both as a sliding door and as a pivoted door. Unless otherwise specified by the manufacturer, the sample for test shall be stored in indoor ambient conditions for at least 24 hours immediately prior to testing. Except for the deflection of shelves (see below), 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.
The test for deflection of shelves (6.1.4), except metal, stone and glass shelves, shall be carried out at a relative humidity of 45 % to 55 %. If during a test the relative humidity is outside this range, the maximum and/or minimum shall be recorded in the test report. 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 carried out as closely as possible to that specified. Before beginning the testing, visually inspect the unit thoroughly. Record any defects so that they are not assumed to have been caused by the tests. Carry out measurements, if specified. During testing, the unit shall be placed on the floor and levelled, unless otherwise specified. All tests specified for a particular component shall be carried out on the same sample. SIST EN 16122:2012
EN 16122:2012 (E) 8 4.2 Application of forces The test forces in the static load tests shall be applied sufficiently slowly to ensure that negligible dynamic force is applied. Unless otherwise specified, each specified force shall be maintained for not less than 10 s and not more than 15 s. The test forces in durability tests shall be applied at a rate to ensure that excessive heating does not occur. Unless otherwise specified, each test force shall be maintained for (2 ± 1) s. The forces may be replaced by masses. The relationship 10 N = 1 kg shall be used. 4.3 Tolerances Unless otherwise stated, the following tolerances are applicable to 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. The accuracy for the positioning of loading pads and impact plates shall be ± 5 mm. NOTE For the purposes of uncertainty measurement, test results are not considered to be adversely affected when the above tolerances are met. 4.4 Prevention of movement during test If a freestanding unit tends to overbalance during the tests specified in Clauses 6 and 7, load the unit until this tendency stops, unless otherwise specified. If a freestanding unit tends to slide during the tests specified in Clauses 6 and 7, with the exception of subclauses 6.4.2 and 6.4.3, the unit shall be restrained by stops (5.3). 4.5 Loading Unless otherwise specified, all storage components, which are not subject to testing, shall be uniformly loaded with the specified load(s). 5 Test equipment and apparatus Unless otherwise specified, the tests may be applied by any suitable device, because results are dependent only upon correctly applied forces and not on the apparatus. The equipment shall not inhibit deformation of the unit/component, i.e. it shall be able to move so that it can follow the deformation of the unit/component during testing, so that the loads are always applied at the specified points and in the specified directions. 5.1 Floor surface, which is a rigid, horizontal and flat surface. For the strength of structure and underframe (6.4.1), the surface shall be smooth high-pressure plastics laminate. SIST EN 16122:2012
EN 16122:2012 (E) 9 For the drop test (6.4.2), the floor shall be faced with a 3 mm thick layer of rubber with a hardness of (85 ± 10) IRHD according to ISO 7619-2:2010. 5.2 Wall surface,, which is a rigid, vertical and flat surface. 5.3 Stops. Devices to prevent the article from sliding but not tilting, not higher than 12 mm, except in cases where the design of the unit necessitates the use of higher stops, in which case the lowest stop that will prevent the item from moving shall be used. 5.4 Loading pad, which is a rigid disc 100 mm in diameter, with a flat face and a 12 mm front edge blend radius. Where space prevents the use of a 100 mm diameter loading pad, a 50 mm diameter loading pad with similar properties may be used. 5.5 Apparatus for slam shut/open of extension elements. Two examples for suitable apparatus as well as calibration instructions are given in Annex A. 5.6 Masses. Masses shall be designed so that they do not reinforce the structure or re-distribute the stresses. NOTE For the deflection of shelves (6.1.4), steel masses with a length of 85 mm, a width of 50 mm, a thickness of 30 mm and a mass of 1 000 g are suitable. 5.7 Glass marbles, which shall be made of solid glass with 10 mm to 15 mm diameter.
They shall be in a flexible bag large enough to allow them to move in the bag during the test.
5.8 Loads for filing pockets. Suspended filing pockets shall be loaded with typing paper or an equivalent alternative as shown in Figure 19. 5.9 Steel impact plates, which are 200 mm in length, with one surface faced with a 3 mm thick layer of rubber with a hardness of (85 ± 10) IRHD according to ISO 7619-2:2010.
Other properties of steel impact plates are as defined in Table 1. Table 1 — Steel impact plates Plate parameter Unit Plate no. 1 Plate no. 2 Mass (excluding rubber) kg 1,7 2,5 Approximate width mm 109 160 Approximate thickness mm 10 10 Length mm 200 200

EN 16122:2012 (E) 10 6 Test procedures for non-movable parts 6.1 Shelves 6.1.1 General Where shelves are structurally interconnected (other than at their ends), all the shelves shall be equally loaded. For units with an indeterminate number of shelves, unless otherwise specified, divide the internal height of the unit, in millimetres, by 200 and take the nearest integer. This number, minus one, shall then be the number of shelves to be fitted. 6.1.2 Shelf retention test – horizontal outward force Apply the horizontal, outwards force specified to the middle of the front edge of the shelf. 6.1.3 Shelf retention test – vertical downward force By means of the 50 mm diameter loading pad (5.4), apply the vertical downwards force specified to a point 25 mm in from the front edge of the shelf at the position most likely to cause failure. 6.1.4 Deflection of shelves Testing of the deflection of shelves, which are not made of metal, glass or stone, shall be carried out in a controlled humidity atmosphere (see 4.1). Place the shelf on its supports in the unit. The deflection of the shelf shall be measured at a point 10 mm from the front edge where the deflection is greatest. The deflection shall be measured to an accuracy of ± 0,1 mm with reference to a straight line parallel to the front edge drawn between two adjacent supports. Load the shelf uniformly (see Figure 2) with the load specified and apply for one hour for shelves made of metal, glass and stone, and one week for all other shelves.
At the same points as specified above, measure and record the deflection under load to an accuracy of ± 0,1 mm and as a percentage of the distance between the supports.
