Abstract
The present invention relates to a method for detecting leaks in a compressed gas supply system (1), the method comprising a first leak-testing phase of the pipeline (8) including at least one leak test based on a controlled vacuum in a section (5, 6) of the pipeline (8), a leak test based on monitoring the variation of a gas parameter when the sections (5, 6) of the pipeline upstream and downstream of a shut-off element (V3a, V4) have a pressure difference, and if the first diagnostic phase is successful, a second leak-testing phase of the pipeline (8) consisting of activating at least one leak test when said sections (5, 6) have the same pressure value.
