A good lubricant should have flash and fire point above its working WHAT PREVENTS THE MAJORITY OF LEAKS FROM BECOMING FIRES? Be exposed to enough air to support combustion but not enough to convert the vapor to smoke. The fire point is always slightly higher than the flash point. At the flash point, a lower temperature, a substance will ignite. 3. This could result in data becoming lost or intercepted during transmission. 5.1 Flash point is one of the properties used to define the flammability of a liquid. At some temperature above the flash point, the liquid will produce enough vapour to support combustion. Please remember that no method of transmission is 100% secure. Most important, you should never fail to perform regular system checks. The flash point is an important concept in fire investigation and fire protection because it is the lowest temperature at which a risk of fire exists with a given liquid. Stay hot enough to continuously generate vapor. | What are the Flash Point and Fire Point? It is crucial in many circumstances to establish the presence of some liquids and to know their flash point during the investigation process. Flash point is the lowest temperature at which a liquid can form an ignitable mixture in air near the surface of the liquid. Until the fire point is reached, should the ignition source be removed, the fluid merely sits there and oxidizes (it smokes). Fire point is defined as the lowest temperature at which the test specimen will sustain burning for five seconds under the specified conditions of the test. FLASH POINT AND FIRE POINT 2. Factors affecting the flash point and fire point of oil Flash point and fire point: The flash point is the lowest temperature to which a lubricant must be heated before its vapor, when mixed with air, will ignite but not continue to burn. Lubrizol collects your contact information in order to communicate with you and provide you with marketing and other information regarding our products.
