And ensure that it meets the conditions stipulated by relevant national laws and regulations.
1 Scope
This standard specifies the test method for the determination of fatty acid methyl esters in aviation turbine fuels by gas chromatography-mass spectrometry.
This standard applies to the determination of various fatty acid methyl esters derived from biodiesel in aviation turbine fuels (see Table 1), total fatty acid methyl esters.
The content range is from 4.5 mg/kg to 140 mg/kg.
Note 1. Aviation turbine fuel (and aviation turbine fuel contaminated by diesel or biodiesel) may contain some hydrocarbon components with higher molecular weight.
These components mask the peaks of trace fatty acid methyl esters. Low-carbon fatty acid methyl esters, such as fatty acid methyl esters obtained from coconut oil, are subject to aviation
The interference of some heavy components in the empty turbine fuel cannot be quantitatively determined at low levels.
Note 2. This standard mainly examines several fatty acid methyl esters listed in Table 1. The mass fraction of these fatty acid methyl esters in common biodiesel is generally 95%.
the above. In addition, methyl heptadecanoate may be present in animal fats such as dairy products and egg yolk lecithin, and is therefore also included.

3 Method summary
After mixing the aviation turbine fuel sample with the internal standard, it is introduced into a gas chromatography-mass spectrometer (GC-MS) and then passed through a polar capillary.
The column is separated to separate a small amount of the fatty acid methyl ester polar compound from the non-polar hydrocarbon compound which is the main component of the aviation turbine fuel.
