Flash point is a safe index for storage, transportation and use of combustible liquids, and also a volatile index for combustible liquids.
Low flash point flammable liquid, high volatility, easy to fire, poor safety.
Petroleum products whose flash point is below 45℃ are inflammable, such as gasoline and kerosene;
Flash point above 45℃ for flammable products, such as diesel oil, lubricating oil.
High volatile lubricants are prone to evaporation loss in the working process, and even cause viscosity increase in severe cases, affecting the use of lubricants.
Generally, the flash point of flammable liquid is required to be 20 ~ 30℃ higher than the service temperature to ensure the safety of use and reduce the loss of volatilization.
Flash point is the item that indicates the evaporation tendency and safety property of petroleum products. The higher the flash point is, the safer it is.
It is forbidden to heat the oil to its flash point during storage and use. The maximum heating temperature should be generally 20~30℃ lower than the flash point.
Flash point is also of great significance in the use of oil products.
The flash point detection of crude oil can be measured by SH105B automatic closed-mouth flash point tester, which adopts micro-computer technology and large-screen LCD.
The instrument is heated according to the standard method, automatic lifting, automatic ventilation, automatic ignition, automatic display, automatic locking flash point value, automatic printing results.
After the completion of the test can be automatically cooled, the work process to achieve full automation.
It has the advantages of accurate measurement, good repeatability, stable performance and simple operation.
Widely used in electric power, petroleum, chemical industry, commodity inspection, scientific research and other departments.
Comply with ISO - 2719,ASTM D93, GB261-2008 standard
