5.1 Vapor pressure is an important physical property of liquid spark-ignition engine fuels. It provides an indication of how a fuel will perform under different operating conditions. For example, vapor pressure is a factor in determining whether a fuel will cause vapor lock at high ambient temperature or at high altitude, or will provide easy starting at low ambient temperature. 5.2 Petroleum product specifications generally include vapor pressure limits to ensure products of suitable volatility performance. 1.1 This test method covers and is
applicable to gasolines and gasoline-oxygenate blends with a vapor
pressure range from 35 to 100 kPa (5 to 15 psi) (see Note 2). This
test method, a modification of Test Method D323 (Reid Method),
provides two procedures to determine the vapor pressure (Note 1) of
gasoline and gasoline-oxygenate blends.
1.2 Some gasoline-oxygenate blends
may show a haze when cooled to 0 to 1°C. If a haze is observed in
1.3 The values stated in SI units
are to be regarded as standard. The values given in parentheses are
for information only.
1.4 This standard does not
purport to address all of the safety concerns, if any, associated
with its use. It is the responsibility of the user of this standard
to establish appropriate safety and health practices and determine
the applicability of regulatory limitations prior to use.
