The device has a first module (10) that comprises a set of spark plugs (14, 15), and second module (11) for transmitting information regarding light emitted by the spark plug during its breakdown. A third module (12) is provided for acquiring transmitted data. A fourth module (13) is utilized for processing and storage of the data. The first module is provided with a metal casing comprising two closed compartments (18, 19), and an electromagnetic compatibility gasket. An independent claim is also included for a method for monitoring ignition strength of a spark plug under electromagnetic stress. L'invention concerne un dispositif et un procédé de surveillance de la robustesse d'allumage d'au moins une bougie (14, 15) soumise à des agressions électromagnétiques. Ce dispositif comprend - un premier module (10) contenant cette au moins une bougie (14,15), - un second module (11) de transport de l'information lumineuse émise par la au moins une bougie lors de son claquage, - un troisième module (12) d'acquisition des données transmises, - un quatrième module (13) de traitement et de stockage de ces données.
