1.1This practice covers procedures and equipment for obtaining, mixing, and handling representative samples of volatile fuels for the purpose of testing for compliance with the standards set forth for volatility related measurements applicable to light fuels.

1.2The applicable dry vapor pressure equivalent range of this practice is 13 kPa to 110 kPa (2 psia to 16 psia).

1.3This practice is applicable to the sampling, mixing, and handling of reformulated fuels including those containing oxygenates. This practice is not applicable to crude oil. For the sampling of crude oil, refer to Practice D4057/API MPMS Chapter 8.1, Practice D4177/API MPMS Chapter 8.2, and Practice D8009/API MPMS Chapter 8.5.

1.4The values stated in SI units are to be regarded as the standard except in some cases where drawings may show inch-pound measurements, which are customary for that equipment.

1.5This 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
