1 Scope and field of application
This International Standard describes methods for determining the stability of free-standing storage furniture, including cupboards, cabinets and bookshelves, that are fully assembled and ready for use.
The tests are not applicable to wall-mounted or otherwise built- in units.
The test results are only valid for tho articic tcstcd. When the test results are intended to be applied to other similar articles, the test specimen should be representative of the production model.
In the case of designs not covered by the test procedures, the test should be carried out as far as possible as described, and a list made of the deviations from the test procedure.
3 Test equipment and conditions
3.1 Vortical forco application dovoo, whch can apply o vertical force, either at a given value or a gradually increasing vdlue. The device shdll not hinder movement of the article being tested. If a given value is wanted, the dcvicc may consist nf a mass, e.g. a steel plate.
3.2 Horizontal force application device, for example spring gauge, which can apply a gradually increasing horizontal force to a shelf.
3.3 Stops, to prevent the article from sliding but not overturning, no higher than 12 mm except in cases where the design of the item necessitates the use of higher stops, in which case the lowest that will plevent the item from sliding shall be used.
3.4 Floor surface, horizontal, flat.
