ASTM D5452 Particulate Contamination in Aviation Fuels by Laboratory Filtration

Scope:

ASTM D5452 test is used for gravimetric measurement of a particulate contaminant isolated by filtration from a sample of aviation turbine fuel. This test method helps to minimize the contaminants and also avoid filter plugging and other operational issues. However, a tolerable level of particulate contaminants has still not been identified for all points in the fuel distribution systems but the total contaminant determination is usually of most concern.

Test Procedure:

For ASTM D5452, a known volume of fuel is filtered through a test membrane filter. The increase in membrane filter mass is calculated gravimetrically after washing and drying. Then, the change in weight of the control filter membrane located immediately below the test filter membrane is also calculated. The particulate contaminant is calculated from the increase in mass of the test membrane relative to the control membrane.

Data:

In ASTM D5452, the total contaminant is calculated in milligrams per liter as follows:

where: 

W₁ =Initial mass of the test filter membrane 

W₂ = Final mass of the test filter membrane

W₃ = Initial mass of the control filter membrane

W₄ =Final mass of the control filter membrane

Conclusion:

ASTM D5452 test is used for gravimetric measurement of a particulate contaminant isolated by filtration from a sample of aviation turbine fuel.
