BF-08 Tester for the gum content in Fuels by Jet Evaporation
|working power supply||AC 220V±10%/50 HZ|
|Overheater heating power||1200W|
|Evaporation bath heating power||2000W|
|Test aperture count||3|
|Flow rate of exit||1000±150ml/s|
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.
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.

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.
