Operating and performing tests with the ROTEST GW 150/4

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 dura-

tion of the test.
The system must be isolated from all other gas carrying systems.

Carry out all bearing 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.
5.2

Leak test of gas fittings pursuant to 1*

For propane liquid gas fittings and low-pressure liquid 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 associat-

ed 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
 Insert the open end of the connecting hose (6) to the valve on the test plug.
 Assemble tube element system as follows:
