188.8.131.52 Method for API Gravity Testing
Collect approximately two volumes--100 milliliters (3.4 ounces) of fuel
sample. Balance the sample to a prescribed temperature (for example, 15°C or
47°F) and transfer the sample to a cylinder prepared at approximately the same
Select an appropriate hydrometer and lower it into the cylinder. Allow the
hydrometer to settle. After temperature equilibrium is attained (approximately 5
minutes), take a temperature reading from the hydrometer scale and record it
according to site procedure.
All parts and tools referred to in the following steps can be identified in
Figure 1.1, page 1-5, or on the test kit placard (see Loading Plan).
