Summary This standard provides a quick method of measuring the amount of fuel oil with a continuous -wave low-resolution nuclear magnetic resonance assay. Under normal circumstances, this standard does not apply to oils used to produce at 20��C was not completely liquid fuel (such as: shea fruit, palm, fog wheatgrass fat, cocoa beans, etc.). The method was validated on the following oils: rapeseed, soybean, sunflower seeds, peanuts. Note 1

1 Scope

This standard specifies the method for rapid determination of the amount of fuel oil using a continuous-wave low-resolution nuclear magnetic resonance assay. Under normal circumstances, this standard is not used to produce oil at 20 ℃ was incomplete liquid fuel (such as. shea fruit, palm, fog Wheatgrass butter, cocoa, etc.). The method is validated for the following oil. rapeseed, soybean, sunflower seeds, peanuts. Note 1. GB/T 14488.1 is a standard method of fuel oil content.
