14.2.1 Interstitial space
The standards EN 13160-4:2003 and EN 13160-7:2003 define the follow-
ing requirements concerning the interstitial space:
• The interstitial space must be designed in such a way that it allows for
the indication of at least 10 l of a specific liquid that is present in the
interstitial space or that penetrates into it.
• The interstitial space must be resistant to the expected thermal, chem-
ical and mechanical loads.
• The interstitial space must be resistant to the stored liquid.
• The liquid in the interstitial space must not be harmful to the stored liq-
uid.
• The interstitial space must be designed in such a way that a monitoring
probe can be installed at the lowest point of the interstitial space.
• The interstitial space must be designed in such a way that the leakage
liquid reaches the lowest point of the interstitial space.
• The tank system must be designed in such a way that there are no con-
nections through the interstitial space to the inner tank below the maxi-
mum filling level.
• The pipe system must be designed in such a way that there are no con-
nections through the interstitial space to the inner pipe.
• It must be possible to inspect the interstitial space for possible damage.
