Non-destructive testing - Leak testing - Characterization of mass spectrometer leak detectors
This European Standard specifies terms and procedures for the characterization of mass spectrometer leak detectors (MSLD). It is not intended to give a complete set of specifications for an acceptance test but a description of procedures that can be used without particular calibration equipment. An MSLD has an integral high vacuum system for maintaining the sensing element (mass spectrometer) at low operating pressure and for establishing a partial pressure related to the incoming gas flow.
Zerstörungsfreie Prüfung - Dichtheitsprüfung - Charakterisierung von massenspektrometrischen Leckdetektoren
Dieser Europäische Norm legt Begriffe und Verfahren für die Charakterisierung von massenspektrometrischen Leckdetektoren (MSLD) fest. Es soll kein kompletter Satz von Spezifikationen für einen Abnahmetest angegeben werden, sondern es werden Vorgehensweisen beschrieben, die ohne spezielle Kalibrierausrüstung angewendet werden können. Ein MSLD hat ein integriertes Hochvakuumsystem, um den Sensor (das Massenspektrometer) bei niedrigem Arbeitsdruck zu halten und einen Partialdruck zu erzeugen, der von dem ankommenden Gasstrom abhängt. Dieser Druck wird vom Massenspektrometer quantitativ gemessen.
Essais non destructifs - Contrôles d'étanchéité - Caractérisation des détecteurs de fuite à spectrométrie de masse
Le présent projet de norme européenne prescrit les méthodes et termes permettant de caractériser les détecteurs de fuites à spectrométrie de masse (DFSM). Elle n'a pas pour objet de donner un ensemble complet de spécifications en vue d'un essai de réception mais elle décrit les procédures qui peuvent être utilisées sans équipement d'étalonnage particulier. Un DFSM possède un système complet de vide poussé permettant de maintenir l'élément détecteur (le spectromètre de masse) à une faible pression de service et d'établir une pression partielle relative au flux de gaz entrant.

Overview - EN 1518:1998 (Non‑destructive testing, Leak testing, MSLD)
EN 1518:1998 is a CEN European Standard that defines terms and procedural guidance for the characterization of mass spectrometer leak detectors (MSLD) used in leak testing and non‑destructive testing (NDT). The standard clarifies how to describe and evaluate the performance of MSLDs and their integral high‑vacuum systems. EN 1518 is intended as a practical procedural reference rather than a prescriptive acceptance‑test specification - it provides methods that can be applied without specialized calibration equipment.
Key Topics and requirements
- Terminology and definitions relevant to mass spectrometer leak detectors and leak testing to ensure consistent communication between manufacturers, test houses and users.
- Characterization procedures that describe how to assess MSLD behavior, sensitivity and response in a practical test environment.
- Vacuum system considerations: guidance on the role of the integral high‑vacuum system in maintaining the sensing element at low operating pressure and establishing the partial pressure that corresponds to incoming gas flow.
- Practical methods that can be carried out without dedicated calibration apparatus; the standard emphasizes reproducible procedures suitable for routine characterization.
- Limitations: EN 1518 does not provide a complete set of acceptance criteria for purchase or final certification tests; it is focused on characterization and consistent measurement practice.
Applications and who uses EN 1518
EN 1518 is relevant to professionals and organizations involved in leak testing, vacuum technology and NDT, including:
- Test engineers and NDT technicians performing leak detector characterization and routine performance checks.
- Manufacturers and suppliers of mass spectrometer leak detectors (MSLDs) who need standardized terminology and procedural descriptions for product documentation.
- Quality and maintenance teams in industries that rely on high‑sensitivity leak detection (aerospace, automotive, semiconductor, medical device manufacturing).
- Calibration and service laboratories that evaluate detector response and vacuum system behavior without access to specialized calibration equipment.
Using EN 1518 supports consistent characterization, clearer supplier‑user communication, and improved reliability of leak testing programs where MSLDs are employed.
Related standards
- EN 1518 complements other European and international standards on non‑destructive testing and leak testing. Users should consult additional EN/ISO standards for acceptance testing, calibration methods and industry‑specific leak‑testing requirements.
