ASTM D3245 Test Method for Pumpability of Industrial Fuel Oils
9. Report
9.1 Report the 0.6 Pa•s (6 P) temperatures as the handling point. Record to the nearest 0.1°C (0.2°F).
9.2 Report the 2.5 Pa•s (25 P) temperature as the storage point. If the 25 P temperature was not reached at 4°C (39°F), report as "less than 4°C (39°F)". Report to the nearest 0.1°C (0.2°F).
10. Precision and Bias
10.1 Precision - The precision of this test method as determined by statistical examination of interlaboratory results is as follows:
10.2 Repeatability - The difference between two test results obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, in the normal and correct operation of the test method, exceed the following values only in one case in twenty:
0.6 Pa•s (6 P) temperature: 0.5°C
2.5 Pa•s (25 P) temperature: 0.5°C
10.3 Reproducibility - The difference between two single and independent results obtained by different operators working in different laboratories on identical test material would, in the long run, in the normal and correct operation of the test method, exceed the following values only in one case in twenty:
0.6 Pa•s (6 P) temperature: 2.9°C
2.5 Pa•s (25 P) temperature: 4.0°C
10.4 These precision values have been obtained by statistical examination of interlaboratory test results between the ASTM and IP and include data from 20 laboratories on seven samples. Tests were conducted under coordination of Subcommittees D02.E.04 and D02.07.0D.
10.5 Bias - There being no established criteria for measuring bias in these materials, no statement of bias can be made.
