Leak detection is nowadays widely used in various fields such as the automotive and refrigeration industries. The leak tightness of installations loaded with refrigerants must be checked periodically by qualified refrigerant detectors using refrigerant leaks. However the latter are not yet traceable. Therefore, a project involving the Laboratoire national de métrologie et d'essais (LNE), the Centre d'énergétique et procédés (CEP) and the Agence de l'environnement et de la maǐtrise de l'énergie (ADEME) was initiated to develop a national standard for calibrating refrigerant leaks. The following document presents the method, the achieved installation and the first results.
