ASTM D4053 Test Method for Benzene in Motor and Aviation Gasoline by Infrared Spectroscopy
13. Report
13.1 Report numerical results to the nearest 0.1 volume %.
14. Precision and Bias
14.1 The precision of the test method as obtained by statistical examination of interlaboratory results is as follows:
14.1.1 Repeatability - The difference between successive test results, obtained by the same operator with the same apparatus under constant operating conditions on identical test materials, would in the long run, in normal and correct operation of the test method, exceed 0.08 volume % only in one case in twenty.
14.1.2 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, in the normal and correct operation of the test method exceed 0.18 volume % only in one case in twenty.
14.2 Bias - There are no interlaboratory test data to establish a statistical statement on bias.
