Non-destructive testing - Leak testing - Characterization of mass spectrometer leak detectors

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.

Non-destructive testing - Thermographic testing - Active thermography with laser excitation
SIST EN 17501:2022

This document specifies a method and establishes guidelines for non-destructive testing using active thermography with laser excitation.
Active thermography with laser excitation is mainly applicable, but not limited, to different materials (e.g. composites, metals, ceramics) and to:
- the detection of surface-breaking discontinuities, particularly cracks;
- the detection of discontinuities located just below the surface or below coatings with an efficiency that diminishes rapidly with a few mm depth;
- the detection of disbonds and delamination parallel to the examined surface;
- the measurement of thermal material properties, like thermal diffusivity;
- the measurement of coating thickness.
The requirements for the equipment, for the verification of the system, for the surface condition of the test object, for the scanning conditions, for the recording, the processing and the interpretation of the results are specified. This document does not apply to the definition of acceptance criteria.
Active thermography with laser excitation can be applied in industrial production as well as in maintenance and repair (vehicle parts, engine parts, power plant, aerospace, etc.).
