This European Standard specifies the connecting dimensions of wall-hung hand rinse basins, regardless of materials used for their manufacture. This standard is not applicable to appliances of actual width of more than 530 mm. NOTE Only dimensions are compulsory. The shape of the appliance in the figures is for illustration only; it in no way prejudices the final shape of the appliance which is left to the initiative of the manufacturer.
