A watertight test apparatus and method for a sewer pipe are disclosed.

A process is disclosed for testing the tightness of a package (11) containing a packaged object (10) and in which a test gas is contained.

Said test medium is used to build up a pressure in the bores (15), the annular groove (16) and the test chamber (14).

Tightness (impermeability) control is carried out after the pipeline is assembled.

The tightness of the tank venting system (20) is checked by overpressure and depression.

The method is useful for checking the electrical imperviousness of the connecting splice insulating means in electrical cables, conducting wire insulation coverings, etc.

The invention concerns a method for monitoring the secure segmentation of applications loaded in a multi-application terminal, said applications having a predetermined structure.

leakage checking of applications containing three kilograms or more of fluorinated greenhouse gases;

The present invention relates in particular to a method for testing the tightness of cavities (4), which are already filled with a stored gas, by charging the cavity (4) with a test gas.

The leaktightness between the nozzle (1) and the container (5) is monitored by injection of a pressurized gas through the tube (10).

Even checking the tightness of vacuum packaging is possible with the optional vacuum set.

Exhaust air heat recovery, on-demand control of ventilation with CO2 sensors and monitoring of air tightness and indoor air quality are strongly recommended techniques.

The invention relates to a method for verifying the leakproofness of a container used for accommodating preferably liquid media as well as a plastic container that is composed of several segments (22a, 24).

The invention relates to a device and method for a controllable dynamic pressure application, in particular for testing sealed package tightness.

If requested by the customer, tests for the strength of the pressurised casing P10, tests for the tightness of the pressurized casing P11 and tests for valve seat tightness P12 may be performed in accordance with EN 12266-1.
