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
EN 13160-3:2003 (E)5 at least 1 l/35 l of leak detector liquid in the interstitial space for all other tanks.NOTEA leak detector liquid tank having a useable volume of less than 1 l/35 l of total liquid volume should not be usedwith tanks buried to a depth of less than 0,3 m earth cover due to the risk of variations in ground temperature causing excessivevariations in the volume of leak detection liquid.The useable volume is considered to be 50 % of the volume between the liquid level existing just before the visualor audible alarm is issued and the top edge of the liquid tank or the air vent (if the latter is located at a lower level).A leak detector liquid tank shall not be connected to more than one storage tank.Several leak detector liquid tanks may be connected in series at the same height, to achieve the required useablevolume of the leak detection liquid.Pipe unions for the interconnecting lines to the interstitial space shall have an internal diameter of 13 mm minimum.They shall be located at the lowest point of the leak detector liquid tank and be designed and secured such that 14 mm outer diameter interconnecting lines cannot be introduced into the leak detector liquid tank.Leak detector liquid tanks shall have a minimum 25 mm internal diameter sealable charging hole.Leak detector liquid tanks shall have a vent hole of minimum 20 mm2 open cross-section. The latter shall bearranged and/or protected such that no clogging by deposits of dirt need be expected. Installation of the vent holein the charging hole cap is disallowed.Leak detector liquid tanks shall be equipped with suitable mounting fixures.A facility for checking the tank level (inspection window or level plug) shall be provided. The latter shall divide thevolume between the liquid level at alarm indication and the top edge of the leak detector liquid tank and/or the venthole in two.Leak detector liquid tanks that are simultaneously intended as a visual indicator shall be adequately transparent orbe equipped with a level indicator.The leak detector liquid tanks shall be positioned so that the hydrostatic pressure of the leak detection liquid at thelowest point of the tank is at least 3 kPa higher than both the maximum pressure of stored product at the lowestpoint of the tank (including any operating pressure) and the maximum pressure of the groundwater at the lowestpoint of the tank.The leak detector liquid tank shall be positioned so that the pressure in the interstitial space shall not exceed therated pressure of the interstitial space.For leak detector liquid tanks installed in a potentially explosive atmosphere the electrical surface resistance shallbe less than 1
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

109conductive connection lines becomes no longer necessary if the outer diameter of the connection lines is
30 mm for potentially explosive atmospheres of group II Aand II B according to EN 50014or the outer diameter of the connection lines is
20 mm for potentially explosive atmospheres of group II Caccording to EN 50014or the wall thickness of the connection lines is < 2 mm for potentially explosive atmospheres of group II Aand II B according to EN 50014 by using conductive leak detection liquidor the wall thickness of the connection lines is < 0,2 mm for potentially explosive atmospheres of group II Caccording to EN 50014 by using conductive leak detection liquid.The flow rate from the outlet of the installed system shall be > 0,5 l/min.As far as possible the inlet and outlet shall be positioned at the extremities of the system to ensure adequate flowof the leak detection liquid.For further information see 7.4 of EN 13463-1:2001.SIST EN 13160-3:2004
