ASTM D3115 Test Method for Explosive Reactivity of Lubricants with Aerospace Alloys Under High Shear
10. Report
10.1 Report the materials used for the dowel pin and block and the identification of the lubricant being tested.
10.2 Report the number and type of reactions for each run of the series. Table 1 illustrates a typical report.
11. Precision and Bias
11.1 Precision - The precision of this test method as determined by the statistical examination of interlaboratory test results involving five laboratories and nine samples is as follows:
11.1.1 Repeatability - Duplicate 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 more than one reaction per set of six runs only in one case in twenty.
11.1.2 Reproducibility - The difference between independent results obtained by different operators working in different laboratories on identical test material would, in the long run, exceed a difference of 108 % of the mean number of reactions only in one case in twenty.
11.2 Bias - No statement is made about the bias of this test method since the results cannot be compared to any form of a standard value.
