- Abstract
- [Abstract in English] We report an easy, practical method for the measurement of the upper flash point. The two small observing windows of a Setaflash closed-cup apparatus were closed to air. A sample was introduced into the cup, left for five minutes, then ignited. The upper flash point could be measured under the vapor-liquid equilibrium state by this procedure. The upper flash points of thirty-three chemicals and three petroleum products were determined. An empirical [equation] was used to calculate the upper flammable-limit temperature, with 5.25 deg C precision, using the observed upper flash point [equation]. The temperature ranges of the cool flame zone could also be measured using sensitive fine thermocouples.
