10 Year Pressure Testing

Fire suppression systems utilise high pressure vessels which must be maintained by law.  The process of test ing is achieved by hydrostatically pressurising the pressure vessel that contains the fire suppression agent.

Hydrostatic pressure testing must be carried out every 10 years. The pressure vessel (fire suppression cylinder) must be decanted, cleaned and dried.  Once the contents and contaminates have been removed the fire suppression cylinder is filled with water.  

As water cannot be compressed, when under pressure it allows us to verify that the cylinder is safe and fit for purpose.  

Fire suppression cylinders are pressurised as follows:

• Inergen - ranging from  bar to 300 bar
• Aragonite 200 bar/300 bar
• ProInert 200 bar/300 bar
• I2 - 200 Bar
• I3 - 300 Bar
• IG55 - 200 Bar/300 Bar
• FM200 - ranging from 25 bar to 42 bar
• Novec1230    - 25 bar
• CO2 - 60 bar

The testing pressure must be 1.5 x that of the wiring pressure, therefor the cylinders are pressure tested to:

• Inergen - ranging from 225 bar to 450 bar
• Aragonite 300 bar/450 bar
• ProInert 300 bar/450 bar
• I2 - 300 Bar
• I3 - 450 Bar
• IG55 - 300 Bar/450 Bar
• FM200 - ranging from 40 bar to 63 bar
• Novec1230    - 40 bar
• CO2 - 90 bar
