Beschreibung
Zusammenfassung:	The invention provides inspection methods and systems for detecting leaks in a vacuum bag assembly (11) used in the manufacture of a composite part based in spraying helium over the vacuum bag (31) and detecting the helium dragged by the vacuum inside the vacuum bag (31) through a leak. The inspection methods comprise creating a local helium atmosphere in a chamber (55) over the vacuum bag assembly (11) by zones following a programmed zonal sequence for a first leak detection test of each zone and a subsequent second leak detection test if the first test gives a positive result. The inspection systems comprise a helium spraying system (61) and a helium detecting equipment arranged to implement said inspection methods.
