To determine the fire point, a sample of a flammable liquid is gradually heated under controlled conditions. The temperature is recorded when the vapors above the liquid ignite and continue to burn for at least 5 seconds. This requires equipment like a Cleveland Open Cup Tester. By ensuring a consistent heating rate and conducting the test in a draft-free environment, reliable results can be achieved. This process helps in understanding fire hazards and ensuring safety in handling flammable liquids.
