Abstract

Method for measuring the leak-tightness of the pipes in an air conditioning system, in which the ends of the pipes 3, 4 are sealed before the test is carried out. The end elements 5, 6, 7 that are fitted in the ends of the pipes are already sealed at the factory, for example by means of a taped plastic film, which is removed after the pressure test has been carried out. <IMAGE>
