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. If the configuration needs to be changed to produce the worst-case conditions, this shall be recorded in the test report.
During testing, the unit shall be placed on the floor and levelled, unless otherwise specified. Levelling devices shall be set to the mid position but not more than 13 mm from the fully closed position.
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.
Doors shall be opened to their maximum but not more than 90° and extension elements shall be fully opened, except where there are no open stops, in which case they shall be opened to two thirds of the internal length. Flaps shall be fully opened.
Extension elements and flaps shall be opened across the full width of the unit. Only one extension element in each vertical line of extension elements shall be opened to produce the configuration most likely to cause overturning.
Unless prominently and durably marked by the manufacturer with a maximum load, the total mass of the unit shall be the weight of the unloaded unit plus the load in the unit when loaded with the loads specified in Table 1.
Apply a vertical force to any point most likely to cause overturning, on the centreline of the front of an extension element or 50 mm from the outer edge of a door or flap.
