BAS EN 1022:2005

This European Standard specifies methods for the determination of the stability of all types of domestic seating which can be used by adults. For seating that can be converted into beds, it applies only to the seating configuration. Chair stability can be determined by either the experimental or the calculative method. These methods are compatible in that they apply the same forces at the same positions. If the result of the calculative method is uncertain or marginal the result should be checked, if possible, by the experimental method.
