1、 Instrument usage:
The open flash point tester is an instrument designed and manufactured in accordance with the methods specified in the national standard GB/T261 "Determination of Flash Point of Petroleum Products (Closed Cup Method)" and the requirements specified in the national petrochemical industry standard SH0315 "Technical Conditions for Closed Flash Point Testers". The open flash point tester measures the lowest temperature of the petroleum product sample (i.e. the flash point of the petroleum product sample) when it is heated in a closed oil cup and produces a mixture of test oil vapor and surrounding air. When it comes into contact with a flame and produces a flash fire.
