ASTM D4559 Standard Test Method for Volatile Matter in Silicone Fluid
9. Precision and Bias
9.1 Repeatability - The difference between results obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, exceed the value of 0.243 only one case in twenty.
9.2 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, exceed the value of 0.565 only one case in twenty.
9.3 Bias - An estimate of bias of -0.032 was obtained for this test method using the spiked values and the measured value of the base oil.
9.4 Limit of Detectability - The limit of detectability was not calculated due to insufficient data.
