3.4.5 Interaction between interstitial space, leak detection medium and operating mode
Regardless whether there is permeation in the interstitial space or
not, the leak detection medium nitrogen is to be used for all applica-
tions if the goods to be conveyed have a flash point
≤
60°C (
≤
55°C
for Germany according to TRGS 509 and TRGS 751).
This specification is based on a risk evaluation according to the di-
rective 2014/34/EU (explosion directive). The risk evaluation was per-
formed based on the table in section 3.3 (informative) for EN 13160.
If the evaluation of the device categories has different results due to
operational regulations or for any other reasons, the use of the leak
detector must be checked separately.
