Cleveland Flash & Fire Point Tester: CLA 5
The automatic Cleveland Open Cup (COC) measures and describes the properties of a sample in response to heat and a test flame under controlled conditions. The flash point measures the tendency to form a flammable mixture with air while the fire point indicates the tendency of sustained burning. CLA 5 is suitable for the application range of volatility, lubricants, residual fuels or bituminous material.
