23、 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, while awaiting the adoption of verifiable European criteria, existing national regu
24、lations concerning the use and/or the characteristics of this product remain in force. BS EN 16146:2012+A1:2014 EN 16146:2012+A1:2014 (E)6 1 Scope This European Standard applies to hoses for extractable outlets of any material intended for equipping sanitary tapware for sinks and basins. Such hoses
25、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 supplies are not covered by this standard. This European Standard specifies: the
26、 dimensional, mechanical and hydraulic characteristics with which the hose for extractable outlets shall comply; the procedures for testing these characteristics.

43、this standard are satisfied; the manufacturers literature, including the installation instructions supplied with the hoses for extractable outlets, indicates clearly that the hoses for extractable outlets are special cases. 8 Hydraulic characteristics 8.1 General The test described is a type test (l
44、aboratory 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 measuring the flow rate through the hoses for extractable outlets u
45、sing 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 with the complete sanitary tapware.
