EN 13905:2003(E)4IntroductionIn respect of potential adverse effects on the quality of water intended for human consumption caused by theproduct covered by this standard:1) This standard provides no information as to whether the product may be used without restriction inany of the Member States of the EU or EFTA.2) It should be noted that, while awaiting the adoption of verifiable European criteria, existing nationalregulations concerning the use and/or the characteristics of this product remain in force.This European Standard specifies requirements for "low resistance" shower hoses suitable for use in lowpressure water supply systems as described in informative annex A.Requirements for shower hoses suitable for use in high pressure water supply systems are specified in EN1113.SIST EN 13905:2004



EN 13905:2003(E)51 ScopeThis European Standard specifies :¾ the dimensional, leaktightness, mechanical and hydraulic characteristics with which shower hoses shallcomply ;¾ the procedures for testing these characteristics.It applies to shower hoses of any material used for ablutionary purposes and intended for connecting showerhandsets to the sanitary tapware of baths and showers. They should only be connected downstream of theobturator of the tapware.Details of pressure and temperature are given in Table 1.Table 1 — Conditions of useLimits of useRecommended limits for correctoperationDynamic pressure0,01 £ P £ 0,2 MPa(0,1 £ P £ 2 bar)0,02 £ P £ 0,1 MPa(0,2 £ P £ 1,0 bar)TemperatureT £ 70 °CT £ 42 °CHoses which are an integral part of sanitary tapware (e.g. sink mixers) or hoses intended to connect sanitarytapware to the water supplies are not covered by this standard.2 Normative referencesThis European Standard incorporates by dated or undated reference, provisions from other publications.These normative references are cited at the appropriate places in the text, and the publications are listedhereafter. For dated references, subsequent amendments to or revisions of any of these publications apply tothis European Standard only when incorporated in it by amendment or revision.
