Abstract

A hollow body 5 to be tested is mounted on a carrier 4 and the carrier is moved along a conveyor 6 onto supports 7 on a base plate 3. A hood 2 is then lowered onto the base plate 3 forming a sealed test chamber 1 enclosing the body 5 on the carrier 4. An external connection is made at 17 to the interior of the body 5, and a differential pressure is established across the wall of the body e.g. by evacuating the chamber 1 surrounding the body 5. A test gas is introduced into the region at higher pressure e.g. the interior of the body 5. A detector specific to the test used is connected to the other region e.g. the chamber at 20. At the conclusion of the test, the hood 2 is raised and the carrier 4 with body 5 still mounted thereon is withdrawn along a conveyor 8. <IMAGE>
