DIN EN 31:2011-11

Economic developments in the sanitary industry and increased demands for comfort as well as distinctive cost awareness by users constantly lead to new product model developments. Both products are, along with bath tubs and shower trays, including shower enclosures, the most important furnishing elements in bathrooms, both in the private sphere as well as in public buildings. The equally growing European goods exchange compels manufactures to not only provide a high product quality, but to define unified possibilities for connection to the building drainage systems and to take these into account for their products. WC pans and wash basins are also affected by these developments. New trends in manufacture and design of the products lead to a new definition of certain connecting dimensions, for which there is consent on the part of the European manufacturers. DIN EN 33 and DIN EN 31 contain exactly these modifications. At the same time, a step in the direction to "clean up" the complete body of standards has been made; these new standards replace the standards DIN EN 31:1999, DIN EN 32:1999, DIN EN 33:2003, DIN EN 34:1992, DIN EN 37:1999, DIN EN 38:1992 and DIN EN 111:2003. The standards have been prepared by CEN/TC 163/WG 3 "Closet bowls, flushing cisterns, urinals, bidets and kitchen sinks" (secretariat: DIN) with significant support from Committee NA 119-05-18-01 UA "Waschtische, Sitzwaschbecken, Klosetts, Urinale" ("Wash basins, bidets, WCs, urinals").
