Room integrity tests and registration of the actual situation regarding the fire protection and holding times in fire compartments in Greece

The need of maximum airtightness is essential in order to ensure that the fire compartment can maintain the required concentration of suppression gas for a specified duration and effectively suppress or extinguish a fire. In Greece there are many facilities with requirements for a high-level protection, but until today, most (if not all) of them have not any integrity test certification. They are complacent by the certifications of the materials applied and the only way to confirm the effectiveness of the room’s integrity is when a fire will take place. 
A number of integrity tests have been made since 2022 and the registration of the results still takes place in various companies and institutions in Greece by the FUV research team. The main purpose of this registration is to complete a list of results regarding the holding time in each room and public the findings. The secondary purpose is to expand the knowledge regarding the existence of this kind of testing.   
The conclusion is that in most cases the holding time is minor than the ISO 14520 defines and there is a need for annual integrity tests is to confirm the reaction of each room.
