23、echanical and hydraulic characteristics with which shower hoses should comply; the procedures for testing these characteristics. This European Standard applies to shower hoses of any material used for ablutionary purposes and intended for equipping and supplementing sanitary tapware for baths and sh
24、owers. This European Standard applies to shower hoses connected downstream of the obturator of the tapware. Hoses which are an integral part of sanitary tapware (sink and wash basin mixing valves) or hoses intended to connect sanitary tapware to the water supplies are not covered by this European St

43、ine the flow rate class (see Table 1). 8.2.3 Apparatus The test apparatus shown in Figure 6, comprises: 1) A supply circuit comprising: a) a means for measuring and maintaining the required pressure of Table 1 with an accuracy of 1 % of the test value; b) a device for measuring the flow rate with an
44、 accuracy of 2 % of the test value; c) a DN15 regulating valve; d) a straight DN15 pipe; e) a pressure take off tee (see Figure 7); f) a pressure measuring device with an accuracy of 1 %. 2) A test circuit comprising: a) a support to maintain the hose in a straight and horizontal position. 8.2.4 Pro
45、cedure Connect the G 1/2 size nut of the shower hose to the pressure take off tee, supporting the hose in a horizontal position. Apply the required dynamic pressure using the horizontal axis of the hose as a datum. Record the flow rate “Q” after stabilization. 8.2.5 Requirements Shower hoses shall b
