标引依据: | 补充修订: | 备注: | 范围:1.1 This test method describes procedures for measuring the vapor pressure of pure liquid or solid compounds. Since no single technique is available to measure vapor pressures from 1 X 10-11 to 100 kPa (approximately 10-10 to 760 torr), two procedures are presented. An isoteniscope (standard) procedure for measuring vapor pressures of liquids from 1 X 10-1 to 100 kPa (approximately 1 to 760 torr) is available in Test Method D 2879. A gas-saturation procedure for measuring vapor pressures from 1 X 10-11 to 1 kPa (approximately 10-10 to 10 torr) is presented in this test method. Both procedures are subjects of U.S. Environmental Protection Agency Test Guidelines.1.2 These two methods were selected to provide data at normal environmental temperatures (10 to 60°C). At least three temperature values should be studied to allow definition of a vapor pressure-temperature correlation. Values determined should be based on temperature selections such that a measurement is made at 25°C (
