Modernization of the flash point tester PE-TVZ for determining fire safety of electrolyte systems of energy-intensive batteries
The flash point tester PE-TVZ was modernized. The sample volume was reduced from 70 to 5 ml. Mixing of the condensed and gas-vapor phases was done simultaneously. The mercury thermometer was replaced by an electronic one. The correctness of the flash point measurement by the modernized device was tested on the samples with the flash point in the range of 25–170°C. The correlation coefficient between the measured flash points of the samples using the flash point tester PE-TVZ and the modernized one was 99.6%, the discrepancy between the measured values not exceeding 1°C. Modernization of the tester made it possible to reduce the amount of samples used by a factor of 14 while maintaining the accuracy of measuring the flash point.
