If we are to measure the flash point of a substance, there are two methods: open cup measurement and closed cup measurement. Once you’ve reached the fire point, it is not enough to simply remove the pan from the heat. Flash point means temp at which vapour of liquid gives momenterley flash when it comes in contact with externel source of fire. Open cup flash point testing occurs when the substance is placed into a vessel which is open to the outside atmosphere. Here, the material starts burning without any effect of an external ignition source, and this ignition occurs at normal atmospheric conditions except the temperature. Hence, the key difference between flash point and fire point is that the flash point describes the lowest temperature at which the ignition of a substance initiates whereas the fire point describes the lowest temperature at which the fuel continues to burn for a short time period after the initiation of the ignition. 1. The flash point is bad enough, but if you reach the fire point””about 700°F – you are in for some trouble. Read Also: What is the difference between HSE, EHS and SHE?

Auto ignition temperature is the lowest temperature that a material can start ignition spontaneously. Also, pressure has no effect on flash point whereas increment of pressure decreases the atuo ignition temperature. Often, the terms fire point and flash point are confusing because they seem the same. Overview and Key Difference Until the fire point is reached, should the ignition source be removed, the fluid merely sits there and oxidizes (it smokes). Korol'chenko 1 Pharmaceutical Chemistry Journal volume 11, pages 993 – 995 (1977)Cite this article. There are various methods of measuring a flash point, which can be divided into two main categories: open and closed cup flash points. What is the difference between ignition temperature and flash point? seems somewhat entertaining on the surface level, but is shot down immediately by simple aspects of how the respective engines are built to run. This is the lowest temperature at which a volatile combustible substance continues to burn in air after its vapors have been ignited and the ignition source removed. The ignition temperature is different from flash point since as at flash point, ignition source will still be required to ignite. Access options Buy single article. The flash point should not be confused with the auto-ignition temperature, which does not require an ignition source.
