Method and arrangement for measuring the flash point of liquids and solids

An arrangement for measuring the flash point of liquids and solids, comprising

• a measuring chamber including a sample cup adapted to contain a sample to be tested and a heatable cover, said sample cup located below said cover,
• an electrical ignition arrangement for igniting the sample,
• a temperature measuring device for measuring and regulating the temperature of said cover,
• a pressing device adapted to press said sample cup from below against the cover such that said sample cup is heated by said cover, the temperature of the sample cup and the sample being lower than the temperature of said cover,
• a pressure measuring device for measuring the increase in pressure in said measuring chamber when the sample is ignited, the flash point of the sample being derived from the measured increase in pressure in said measuring chamber when the sample is ignited.

An arrangement for measuring the flash point of liquids and solids comprising

• a sample cup filled with the sample to be tested,
• a heatable cover pressed firmly to said cup, forming a metal sealed closed measuring chamber,
• a pressing device adapted to press said sample cup from below against said cover,
• a heating device arranged in said cover such that said sample cup is heated by said cover and the temperature of the sample cup is lower than the temperature of said cover,
• an electrical ignition arrangement for the ignition of the flammable vapor from the sample,
• a first temperature sensor for measuring and regulating the temperature of said cover,
• a second temperature sensor for regulating and measuring the temperature of said sample,
• a pressure measuring device for measuring the increase in pressure in said measuring chamber when the sample is ignited, the flash point of the sample being derived from the measured increase in pressure in said measuring chamber when the sample is ignited.
