The mounting and

35、operating conditions for draw-off taps and mixing valves are described in ENISO3822-2 whereas EN ISO3822-3 describes the mounting and operating conditions for in-line valves and appliances. This part of EN ISO3822 describes the mounting and operating conditions for laboratory tests of appliances of

36、such construction that they cannot easily be considered as draw-off or in-line appliances, e.g. water heaters, shower heads, etc. 1 Scope This part of EN ISO3822 specifies the mounting and operating conditions to be used for a number of appliances which cannot be regarded as draw-off orin-line valve

Special appliances, including connecting pipe, shall be connected to the union using if necessary a combination of galvanised (hot-dip zinc coated) fittings complying with ISO49. Changes in direction shall be accomplished by means of long sweep bends size1 only.

44、Reduction or enlargement of size shall only be made at the inlet connection of the appliance or connecting pipe. The combination of fittings used shall result in the appliance being mounted in the normal position of use (seeFigure 1). 3.2 Float-operated valves 3.2.1 General A float-operated valve no

48、an300 mm. If another type of connection is supplied, the connection to the test pipe shall be made, as far as possible, as in the field. When a compression fitting is used, a copper connecting pipe shall be inserted into the appliance, according to the manufactures instructions. There shall be no st

49、op-valve between the appliance and the appliance connection at the end of the test pipe, unless it belongs to the unit. The test cistern shall be fixed acoustically independent of the test wall. 3.2.3 Operating conditions Float-operated valves shall be tested at flow pressures of0,3MPa and0,5MPa 1) , adjusted when the valve is in the fully open position and maintained during closing.
