Non-destructive testing - Leak testing - Pressure change method
This standard describes the techniques for the determination of the rate of leakage across the boundary of an isolated object, subjected to a pressure difference. The techniques are based on the evaluation of the change of the mass of gas within the test object. The ideal gas equation states the relationship between mass, pressure, temperature and volume of the gas contained in the internal free volume of the object. In some circumstances one or more variables may be considered constant and so the mass change can, for example, be assessed by monitoring the pressure or pressure-temperature changes within the test object.
Zerstörungsfreie Prüfung - Dichtheitsprüfung - Druckänderungsverfahren
1 Anwendungsbereich
Diese Europäische Norm legt die Verfahren zur Bestimmung der Strömung durch Lecks in der Umwandung
eines abgeschlossenen Prüfobjektes, das einem Druckgefälle ausgesetzt ist, fest. Die Verfahren beruhen auf
der Auswertung der Änderung der Gasmasse innerhalb des Prüfobjektes. Die Zustandsgleichung für ideale
Gase gibt das Verhältnis zwischen Masse, Druck, Temperatur und Volumen des Gases an, das im freien Innen-volumen
des Prüfobjektes enthalten ist. Unter bestimmten Umständen dürfen eine oder mehrere Variable als Seite 3
EN 13184:2001
konstant angenommen werden, und damit kann die Massenänderung zum Beispiel durch Kontrolle der
Druckänderung oder der Druck-Temperatur-Änderung innerhalb des Prüfobjektes beurteilt werden.
Die Volumenänderung des Prüfobjektes (aufgrund von Druck- und Temperaturänderung bei der Prüfung) sollte
berücksichtigt werden. In den meisten industriellen Anwendungen ist diese Änderung jedoch so klein, dass sie
vernachlässigt werden kann. Im größten Teil dieser Norm wird deshalb das Volumen während der Prüfung als
konstant angenommen.
Die Verformbarkeit des Prüfobjektes wird üblicherweise bei der Planung der Prüfspezifikation berücksichtigt
werden, und wenn die Prüfgenauigkeit durch eine Volumenänderung beeinflusst werden kann, können alternative
Formeln oder Verfahren, bei denen der Druck konstant gehalten wird (Strömungsmessung), angewendet
werden.
Essais non destructifs - Contrôle d'étanchéité - Méthode par variation de pression
Ce projet de norme décrit les techniques de détermination des flux de fuite de part et d'autre de la paroi d'un objet isolé, soumis à une différence de pression. Ces techniques se basent sur l'évaluation de la variation de la masse de gaz à l'intérieur de l'objet contrôlé. L'équation d'un gaz parfait établit la relation entre masse, pression, température, et volume d'un gaz présent dans le volume interne vide de l'objet. Dans certaines circonstances, une ou plusieurs variables peuvent être considérées comme constantes et ainsi, toute variation de masse peut être évaluée en surveillant, par exemple, les variations de pression ou de pression-température survenant à l'intérieur de l'objet contrôlé.
Il y a lieu de tenir compte des variations de volume de l'objet (dues à des variations de température ou de pression pendant le test). Cependant, dans la plupart des applications industrielles, ces modifications sont si infimes qu'elles peuvent être considérées comme négligeables. En règle générale, dans la présente norme, le volume sera considéré comme une constante pendant le test.
La déformabilité de l'objet contrôlé est généralement prise en compte pour établir les spécifications du test et si la précision du test peut être affectée par une variation de volume, d'autres formules ou des techniques permettant de maintenir la pression constante (mesure de flux) peuvent être utilisées.

Overview
The EN 13184:2001/A1:2003 standard, issued by CEN, defines procedures for non-destructive leak testing using the pressure change method. This internationally recognized standard outlines techniques to determine leakage rates by monitoring variations in gas mass within an isolated object subject to a pressure difference. Through the application of the ideal gas law, which correlates mass, pressure, temperature, and volume, this method provides accurate and reliable leak detection without damaging the test object.
By focusing on pressure and temperature measurements, EN 13184 enables the assessment of leakage integrity in various industrial systems. This standard is essential for organizations that require precise leak testing to ensure safety, performance, and compliance with regulatory requirements.
Key Topics
- Non-destructive Testing (NDT): EN 13184 emphasizes leak detection methods that preserve the integrity of the test item, avoiding damage while providing sensitive leak rate evaluation.
- Pressure Change Method: Central to this standard, the technique measures changes in gas pressure or the combined pressure-temperature product within a sealed object to infer leak rates.
- Ideal Gas Law Application: Utilizes the relationship between pressure (P), volume (V), temperature (T), and gas mass (m) to calculate leakage by observing physical changes inside the test volume.
- Measurement Variables: Depending on test conditions, some variables (temperature or volume) may be considered constant to simplify calculations and improve assessment accuracy.
- Test Object Isolation: The method requires the item being tested to be hermetically isolated to ensure the pressure change is solely due to leakage.
Applications
EN 13184:2001/A1:2003 is applicable in various industries where leak tightness is critical:
- Aerospace: Testing aircraft components to ensure airtightness and prevent fuel or gas loss.
- Automotive: Verifying seals, fuel tanks, and air conditioning systems for leaks that could affect vehicle safety or performance.
- Pharmaceutical and Medical Devices: Ensuring sterility and containment by detecting micro-leaks in packaging or equipment.
- Manufacturing of Pressure Vessels and Containers: Assessing the integrity of gas cylinders, pipelines, and storage tanks.
- HVAC Systems: Maintaining efficiency and safety by detecting leaks in ductwork and sealed components.
- Electronics: Protecting sensitive devices by confirming their enclosures are leak-proof.
Employing EN 13184-based testing helps reduce downtime, maintenance costs, and environmental impact due to gas leakage while guaranteeing product quality and regulatory compliance.
Related Standards
When implementing leak testing according to EN 13184, other complementary standards may be referenced to enhance testing protocols:
- EN 13185: Covers alternative leak testing methods, including tracer gas and vacuum techniques.
- ISO 20484: Specifies vocabulary for leak testing to maintain terminology consistency.
- EN 1779: Provides general principles and vocabulary for non-destructive leak testing.
- ASTM E515: Defines vacuum chamber methods for leak detection, often cross-applied with pressure change tests.
- ISO 9001: Supports quality management systems that incorporate standardized leak testing as part of process control.
Using EN 13184 alongside these standards ensures comprehensive leak detection strategies that fulfill safety, environmental, and quality demands.
By adhering to EN 13184:2001/A1:2003, industries can effectively implement robust, non-destructive leak testing protocols using the pressure change method, guaranteeing integrity and reliability in critical applications. This standard is a key resource for quality assurance professionals, engineers, and safety inspectors focused on precise leak identification and control.
