PARTICULATE CONTAMINATION IN AVIATION FUEL: ASTM D2276
(Equivalent Test Method: IP 216)
EXPLANATION
This test method uses a field monitor. Two methods are described. One measures gravimetrically. The other uses a color rating technique for rapid qualitative assessment of changes in contaminant level without the time delay required for gravimetric determinations in the laboratory.
TEST SUMMARY
In the field monitoring test, a sample of fuel is taken from a flowing line or pipe and passed under line pressure through a field monitor containing a 0.8 μm test filter membrane. The color on the filter membrane is compared with the ASTM color standards and assigned a rating letter and number.
TEST PRECISION
Repeatability: 0.175X + 0.070
Reproducibility: 0.444X + 0.178
Where X is the average value of two results.
This precision is based on the range from 0.0 to 2.0 mg/L.
This test method has no bias.
