The "JJF 1384-2012 Open/Closed Cup Flash Point Tester calibrating specification" standard applies to the calibration of Cleveland open cup method flash point tester and Binsky Martin closed cup method flash point tester. This standard specifies the calibration method of flashpoint tester in detail, including the principle of calibrating, calibrating procedure and processing requirements of calibrating data. The standard cites "GB/T 261-2008 Determination of flash point, Binsky Martin closed cup method" and "GB/T 3536-2008 Determination of flash point and ignition point of petroleum products, Cleveland open cup method" and other documents. Through the implementation of this standard, the accuracy and reliability of flashpoint testers in flash point determination can be ensured, providing technical support for testing and research in related industries.
