Foam producing solutions for leak detection on gas installations

This document specifies requirements and test methods of foam producing solutions for leak detection (hereafter called leak detection solution) used for leak detection of combustible gases of the 1st family (town gas), 2nd family (natural gas), and 3rd family (liquefied petroleum gases (LPG)) (see EN 437) within the temperature range of -15 °C or 0 °C to 50 °C. It is applicable for leak detection solutions, which are delivered as ready to use solutions, e.g. in spray cans.
Note   The leak detection solution covered by this document may also be used for other compressed gases. In this case the producer has to be consulted.

Schaumbildende Lösungen zu Lecksuche an Gasinstallationen

Diese Europäische Norm legt Anforderungen und Prüfverfahren für schaumbildende Lösungen zur Lecksuche (nachfolgend Lecksuchlösungen genannt) zum Nachweis von Leckagen brennbarer Gase der 1. Familie (Stadtgas), der 2. Familie (Erdgas) und der 3. Familie (Flüssiggas) (siehe EN 437) innerhalb des Temperaturbereiches von - 15 °C oder 0 °C bis 50 °C fest. Sie gilt für Lechsuchlösungen, die als gebrauchsfertige Lösungen z.B. in Sprühdosen ausgeliefert werden.
ANMERKUNG Die Lecksuchlösungen nach dieser Europäischen Norm können auch für andere verdichtete -Gase verwendet werden. In diesem Fall ist der Hersteller um Rat zu fragen.

Solutions moussantes pour détection de fuites sur les installations de gaz

La présente norme européenne précise les exigences et les méthodes d'essai relatives aux solutions moussantes pour détection de fuites (que l'on appellera solutions pour détection de fuites) en vue de la détection de fuites des gaz combustibles de la 1ere famille (gaz manufacturés), de la 2eme famille (gaz naturel), et de la 3eme famille (gaz de pétrole liquéfiés (GPL)) (voir l'EN 437) sur une échelle de températures comprises entre -15 °C, ou 0 °C et 50 °C. La présente norme est applicable aux solutions pour détection de fuites qui sont pretes a l'usage, comme par exemple les aérosols.
NOTE   La solution pour détection de fuites conforme a la présente norme peut aussi etre employée pour d'autres gaz comprimés. Dans ce cas il faut consulter le fabricant.

SIST EN 14291:2005



EN 14291:2004 (E) 4 Introduction There are different methods to detect and localize leaks on gas installation and gas equipment. One commonly used method is the application of surface-active aqueous solutions of detergents that produce foam on leaking gas installations. This standard specifies several important requirements for foam producing solutions especially for the detection of small leaks e.g. surface tension, foam stability, corrosiveness, and compatibility with sealing materials and lubricants. It should be mentioned that excessive and repeated use of these aqueous detergent solutions on old threaded joints sealed with natural fibres (e. g. hemp or flax) and unsuitable sealing materials can temporarily seal a leaking joint by swelling of the natural fibres. Since some plastic and copper pipe materials may be attacked by surface-active aqueous solutions of detergents used for leak detection, it is generally recommended to rinse plastic and copper pipes with water after leak detection by foam producing solutions according to this standard.
