5.1.3

Leak low-pressure liquid gas fittings test pursuant to 1*

Complete test as follows:
Close all cut-off valves on your ROTEST GW 150/4.
Insert connecting hose (6) to connecting valve B. An auditable sound is heard when hose
and valve nipple are properly locked.
Insert an appropriate test plug into the open end of the pipe and seal off end by turning the
wing nut until the pipe is sealed tight.
Insert the open end of the connecting hose (6) to the valve on the test plug.
Assemble tube element system as follows:
while carefully turning insert tube element (8) with scale 40 - 60 mbar into fixed tube
-
element (7).
Seal off the hose end of the bellow (12) by sliding end over connecting valve C on the
water tank.
Open connecting valves B, C and D.
Use bellow (12) to load a pressure pursuant to 1* into the test system.
Close connecting valve C to avoid a loss in pressure.
Wait 10 minutes for loaded air and water temperatures to equalize.
Prolong 10-minute period of temperature equalization if temperatures fluctuate
greatly. The equalization period can last up to two hours!
Carry out the test over a period prescribed by 1*. Over this period the pressure indicated must
not drop.
