24、: This European Standard provides no information as to whether the product may be used without restriction in any of the Member States of the EU or EFTA. While awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this p

25、roduct remain in force. DIN EN 1113:2015-06 EN 1113:2015 (E) 6 1 Scope This European Standard specifies: the dimensional, leaktightness, mechanical and hydraulic characteristics with which shower hoses should comply; the procedures for testing these characteristics. This European Standard applies to

26、 shower hoses of any material used for ablutionary purposes and intended for equipping and supplementing sanitary tapware for baths and showers. This European Standard applies to shower hoses connected downstream of the obturator of the tapware. Hoses which are an integral part of sanitary tapware (

27、sink and wash basin mixing valves) or hoses intended to connect sanitary tapware to the water supplies are not covered by this European Standard. Details of pressures and temperatures are given in Table 1. Table 1 Conditions of use/Classifications Water Supply system Operating range of shower hoses
