maintain it at 0.80 bar for another 5 minutes, it means that the hole is too large to
be repaired by the product. It is also possible to have several micro- leaks that can
therefore be repaired. Nitrogen may also be used to measure the degree of leaks.


3 - Create and maintain a depression of 0.80 bar for at least 30 minutes to extract
humidity completely from the system.
