适用范围
This International Standard specifies a method for the determination of the gauge vapour pressures (see note 1) of liquefied petroleum gas products (see note 2) at temper-atures of 37,8 °C up to and including a test temperature of 70 °C. NOTES 1 Information on the gauge vapour pressures of liquefied petroleum gas products under test temperature conditions in the range from 37.8 to 70 °C is pertinent to problems of selecting properly designed storage vessels, shipping containers, and customer utilization equipment to ensure the safe handling of such products. 2 For the purpose of this test method, liquefied petroleum gas products are defined as narrow boiling range hydrocarbon mixtures consisting predominantly of propane or propylene, or both, butanes or butylenes, or both, in which the content of hydrocarbon compounds of boiling point higher than 0°C is less than 5 % by liquid volume, and whose gauge vapour pressure at 37.8 °C is not greater than approximately 1 550 kPa.1)
