Guidance on laboratory testing for biodegradation of organic chemicals in soil underaerobic conditions.3 Terms and definitionsFor the purposes of this European Standard, the terms and definitions given in EN 13160–1:2003 apply.4 GeneralGeneral principles according to EN 13160–1.Additionally the type of leak detection liquid shall be given.Where the requirement is for low temperature performance the alternative test temperature is shown in brackets[.].5
Interstitial spaceGeneral requirements concerning the interstitial space according to EN 13160-7.The interstitial space shall be constructed such that the entire volume can be filled with the leak detection liquid andit shall be liquid tight.The walls of the interstitial space shall withstand the pressure due to the head of liquid in the system.For a tank the system shall be designed so that there are no connections to the inner tank through the interstitialspace below the maximum filling level.Access into the interstitial space of tanks shall only be allowed through the outer skin above the maximum fillinglevel.6 Leak detector for liquid systems6.1 Leak detector liquid tanksThe leak detector liquid tanks - being expansion tanks - shall have a useable volume of:¾ at least 1 l/100 l of leak detector liquid in the interstitial space of tanks with at least 0,3 m earth cover;SIST EN 13160-3:2004

109 , if the greatest projected surface is > 100 cm2. For further information see 7.4 ofEN 13463-1:2001.The pipe connection shall be designed so that it is not possible for the interconnecting pipe to protrude above thelower inside surface of the leak detector liquid tank.6.2 Leak detection liquidsThe manufacturer shall specify which leak detection liquids are suitable for the leak detection system. Leakdetection liquids shall have the following properties: electrical conductivity greater than 10 mS/m; viscosity at - 20 C [- 40 °C] not greater than 100 mm2 s-1 and a freezing point below - 20 C [- 40 °C]; flash point not below + 80 C; coefficient of thermal expansion not exceeding 5
10 -4 K -1 at a temperature of + 20 C;SIST EN 13160-3:2004
