Fire Testing of NGV Cylinders. Natural Gas Vehicles Summary Various fire testing methods to evaluate the resistance of natural gas vehicle cylinders to fire effects and the ability of fire protection systems to prevent the failure of the cylinders are compared. The requirements for the fire testing of gas cylinders are not specific.
Tests conducted by manufacturers use various fuel sources and vary in intensity and duration.
This study reviews the available results of fire tests conducted on cylinders of different design and using different methods, and the actual fire tests, using various fuel sources, conducted at Powertech Labs for the purpose of determining temperatures generated on steel cylinders. Trends in the test data indicate that gasoline fires typically generate twice the heat input of wood bonfires, and that fires on horizontal cylinders have about twice the heat input of vertical cylinders. It is determined that any fire source can be used for fire testing provided it supplies sufficient heat of constant intensity for the required duration of time.
