Working method:collect 100mL of liquefied petroleum gas cooled by coolant in the vaporization tube and vaporize it under specific conditions. Measure the temperature at which liquefied petroleum gas vaporizes at 95% (V/V). The vaporization temperature is affected by changes in atmospheric pressure, and measurements under non-standard conditions require atmospheric pressure correction.
