Applicant's summary and conclusion

Conclusions:
the vapour pressure of the test item at 25°C is 0.00913 Pa.
Executive summary:

It is considered that the carrier gas was sufficiently saturated with the test item at each flow rate because three measured values at each temperature were very near. it is also considered that the measured vapor pressure was well-correlatd to the test temperature because the regression equation obtained by plotting the logarithm of vapor pressure (log P) versus the reciprocal number oftest temperature (1/T) was straight line. Therefore, it is considered that the test results are acceptable.
