CEN/TC 393/WG 2 - Leak detecting devices for tanks and pipes

This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits (leak detector) based on the measurement of pressure change. Leak detection kits are intended to be used with double skin, underground or above ground, pressurized or non-pressurized, tanks or pipework designed for water polluting liquids/fluids. The kits are usually composed of:
-   measuring device;
-   evaluation device;
-   alarm device;
-   pressure generator;
-   pressure relief device;
-   liquid stop device;
-   condensate trap.

This standard gives requirements and the corresponding test/assessment methods applicable to leak detection lining kits and leak detection jacket kits. Leak detection lining kits and leak detection jackets kits intended to be used as post-installed to create an interstitial space or leakage containment in single skin underground or above ground, non-pressurized, tanks designed for water polluting liquids. The kit has to be used only in conjunction with leak detection kits covered by prEN 13160-2 to prEN 13160-4.

This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits based on the detection of the presence of liquid and/or vapour in interstitial spaces, leakage containments or monitoring wells. The kits are usually composed by:
- sensing device(s);
- evaluation device;
- alarm device.

This European Standard specifies the general principles for leak detection systems for use with double-skin tanks, single-skin tanks and pipework designed for water polluting fluids.

This European Standard gives requirements and the corresponding test/assessment methods applicable to leak detection kits based on the drop of the liquid level in the leak detection liquid reservoir. Leak detection kits are intended to be used with double skin, underground or above ground, non-pressurized, tanks designed for water polluting liquids.
The liquid leak detection kits are usually composed of:
- sensing device (liquid sensor);
- evaluation device;
- alarm device.

This standard gives requirements and corresponding test\assessment methods applicable to leak detection kits, based upon volumetric loss from within the tank and/or pipework system. The kits usually comprise:
- Measuring Device
- Evaluation Device
- Alarm Device
Intended use:
Leak Detection kits are intended to be used in\with single or double skin underground tanks or single or double skin underground and/or aboveground, pipework designed for flammable liquids having a flash point not exceeding 100 °C.

This European Standard specifies the requirements for leak detection systems - class V for use with systems designed for fuels which are flammable, having a flash point up to but not exceeding 100 °C.

This European Standard specifies the general principles for leak detection systems for use with double-skin
tanks, single-skin tanks and pipework designed for water polluting fluids.

This European Standard specifies the requirements for leak detection systems – class II for use with doubleskin
tanks designed for water polluting fluids.

This draft European Standard specifies the requirements for leak detection systems, class IV, for use only with liquids as defined in the scope of EN 13352:2002.
