• sealed parts: leak test of sealed components, with an internal cavity but with-
out external connections, inside a test chamber (bell jar).
5.7.1 Volume+leak test: test cycle
The volume of a tested component can be controlled by applying the well-known rule
for the relationship between pressure and volume of a gas (P * V = constant).
For volume control, an external valve (option) is used, mounted between the TEST
output of the instrument and the tested component or the interspace of the test
chamber (bell jar).
