This test method covers the determination of the existent gum content of aviation fuels, and the gum content of motor gasolines

or other volatile distillates in their finished form,(including those containing alcohol and ether type oxygenates and deposit

control additives) at the time of test.

Provisions are made for the determination of the heptane insoluble portion of the residue of non-aviation fuels.

The accepted SI unit of pressure is the Pascal(Pa); the accepted SI unit for temperature is degrees Celsius.

3.Summary of Test Method

A measured quantity of fuel is evaporated under controlled conditions of temperature and flow of air or steam. For aviation

gasoline and aviation turbine fuel, the resulting residue is weighed and reported as milligrams per 100mL. For motor gasoline,

the residue is weighed before and after extracting with heptane and the results reported as milligrams per 100mL.

4.Performance characteristics

The intelligent instrument controls the super-heater temperature and the metal bath’s temperature, so it is safe and reliable; and there are 3 holes.

5.Applicable standards

GB/T8019 ASTM D381

6.Significance and Use

The true significance of this test method for determining gum in motor gasoline is not firmly established. It has been proved

that high gum can cause induction-system deposits and sticking of intake valves, and in most instances, it can be assumed that low gum will ensure absence

of induction-system difficulties. The user should, however, realize that the test method is not of itself correlative to induction-system deposits. The primary purpose of the test method, as applied to motor gasoline,is the measurement of the oxidation

products formed in the sample prior to or during the comparatively mild conditions of the test procedure. Since many motor

gasolines are purposely blended with nonvolatile oils or additives, the heptane extraction step is necessary to remove these

from the evaporation residue so that the deleterious material, gum, may be determined. With respect to aviation turbine fuels,

large quantities of gum are indicative of contamination of fuel by higher boiling oils or particulate matter and generally reflect

poor handling practices in distribution downstream of the refinery.
