ASTM D6379 Standard Test Method for Determination of Aromatic Hydrocarbon Types in Aviation Fuels and Petroleum Distillates - High Performance Liquid Chromatography Method with Refractive Index Detection
12. Report
12.1 Report MAH, DAH, and total aromatic hydrocarbon contents to the nearest 0.1 % m/m.
12.2 The test report shall contain at least the following information:
12.2.1 A reference to this standard;
12.2.2 The type and identification of the product tested;
12.2.3 The result of the test (see Section 11);
12.2.4 Any deviation, by agreement or otherwise, from the procedure specified;
12.2.5 The date of the test.
13. Precision and Bias
13.1 Precision - The following criteria should be used for judging the acceptability of results (95 % probability):
13.1.1 Repeatability - The difference between two results obtained by the same operator on 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:
13.1.2 Reproducibility - The difference between two single and independent results obtained by different operators working in different laboratories on identical test materials 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:
13.1.3 Bias - The results of this test method are defined in terms of the test method, and hence, the procedure has no bias.
