The ASTM D4052 standard is published by ASTM International (formerly American Society for Testing and Materials, as of 2001 “ASTM International”). The standard defines the test method used for determining the density, relative density, and API Gravity of petroleum distillates and viscous oils.
The procedure defined by ASTM D4052 is used to test, for example:
- gasoline-oxygenate blends
- jet fuel
- lubricating oils
