scope:

This standard specifies constructional and performance requirements together with the test methods for close-coupled suites one-piece WCs and independent WC pans with integral trap used for personal hygiene manufactured from glazed ceramics or stainless steel. This standard does not apply to squatting toilets, WC pans without integral trap, flushing cisterns as separate appliances. In case of independent WC pans, the associated flushing cisterns and pressure valves are covered by other standards and the reference to flushing cisterns is related only to the definition and requirements of flushing volume. In case of close-coupled suites and one-piece WCs, this standard also specifies design, performance requirements and the test methods for designated flushing cisterns with flushing mechanism, inlet valve and overflow. For these products, this standard covers flushing cisterns designated to be connected to drinking water installations inside buildings. Before installation of WCs, EN 12056-2 and national regulations shall be taken into account.
