ISO 817 Annex C Gas Burning Velocity Test Apparatus is used to measure the burning velocity of flammable gas with air mixed, such as refrigerants, li-ion battery thermal runaway venting gas, by testing on synthetically replicated gas.
The flammable gas is pre-mix with air in a tank, and the homogeneous flammable gas-air mixture is introduced to the 1,200mm glass tube with an internal diameter of 40mm, and is ignited with the electrodes mounted at the bottom position of the glass tube. The flame will propagate from the lower to the upper end with a constant propagation speed at the flame front. The flame propagation inside the tube is recorded using a high-speed camera and the images are then transmitted to the computer for measuring the flame propagation speed and calculating the flame front area. The flammable gas's Burning Velocity (Su) is obtained by dividing the consumed mixture volume by the frame surface area.
