24、 potential adverse effects on the quality of water intended for human consumption caused by the product covered by this standard, this 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. It should be noted that, wh

25、ile awaiting the adoption of verifiable European criteria, existing national regulations concerning the use and/or the characteristics of this product remain in force. DIN EN 16146:2015-02 EN 16146:2012+A1:2014 (E) 6 1 Scope This European Standard applies to hoses for extractable outlets of any mate

26、rial intended for equipping sanitary tapware for sinks and basins. Such hoses will only be connected downstream of the obturator of the tapware. The tapware will comply with EN 200, EN 817, EN 1111, EN 1286 or EN 1287 (see 1, 2, 3, 5 and 6). Hoses intended to connect sanitary tapware to the water su

27、pplies are not covered by this standard. This European Standard specifies: the dimensional, mechanical and hydraulic characteristics with which the hose for extractable outlets shall comply; the procedures for testing these characteristics. Details of pressures and temperatures are given in Table 1.

45、haracteristics 8.1 General The test described is a type test (laboratory test) and not a quality control test carried out during manufacture. 8.2 Flow rate 8.2.1 Test method This clause describes a method for testing the flow rate of hoses. 8.2.2 Principle The principle consists of a method for meas

46、uring the flow rate through the hoses for extractable outlets using cold water (T 30 C) in order to determine the flow rate class of the hose (see Table 1). The flow rate of hoses for extractable outlets with special connection (see 7.3) delivered together with the tapware is measured in combination

47、 with the complete sanitary tapware.
