Operating And Performing Leakage Tests With The Rotest Gw 150; Bearing Test Of Gas Fittings Pursuant To 1; Leak Test Of Gas Fittings Pursuant To 1 - Rothenberger ROTEST GW 150/4 Instrucciones De Uso

Use bellow (12) to load a pressure of 110 or 150 mbar into the test system (zero level in the
upper tube element).
Close connecting valve C to avoid a loss in pressure.
Wait 10 minutes for loaded air and water temperatures to equalize.
Prolong period of temperature equalization if temperatures fluctuate greatly!
Carry out test over a period of ten minutes. The indicated pressure should not drop over a 10-
minute period.

5.1

Bearing test of gas fittings pursuant to 1*

The following aspects must be taken into careful consideration:
• All bearing tests are to be performed on newly fitted gas pipe systems without fixtures.
• All pipe openings must be sealed off with plugs, caps, blanks or blind flanges for the duration
of the test.
• The system must be isolated from all other gas carrying systems.
• Carry out all initial tests before the pipes are plastered or covered and the joints are coated or
jacketed.
• If the test is to be carried out at the gas meter end of the pipe system, use the threaded
supply-end cap (22) to seal off the pipe system.
Complete test as follows:
Close all cut-off valves on your ROTEST GW 150/4.
Insert connecting hose (6) to connecting valve A. 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.
Use the hand pump to load a pressure pursuant to 1* to the pipe system.
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.
5.1.1

Leak test of gas fittings pursuant to 1*

The following aspects must be taken into careful consideration:
• The leak test gas fitting includes all fixtures, but not gas appliances as well as the associated
control and safety devices.
•
The system must be isolated from all other gas carrying systems.
•
Carry out all leak tests before the pipes are plastered or covered and the joints are coated or
jacketed.
•
The gas meter may be included in leak tests.
• If the test is to be carried out at the gas meter end of the pipe system, use the threaded
supply-end cap (22) to seal off the pipe system.
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
