This European Standard specifies requirements for the connecting dimensions for shower trays, regardless of the material used for their manufacture. This European Standard applies to shower trays used for domestic purposes and complements the standards for shower trays made from different materials, the existing standard on waste fittings (EN 274-1) in terms of their dimensional requirements. NOTE Only dimensions are compulsory. The shape of the appliance in the figures is for illustration only; it in no way prejudices the shape of the appliance which is left to the initiative of the manufacturer.
