16. Report
16.1 Report the filter deposit mass, the rod deposit mass, and the total deposit mass, all to the nearest 0.1 mg.
17. Precision
17.1 Interlaboratory study test results are shown in Table 2.
17.2 The precision of this test method as determined by the statistical examination of the interlaboratory study test results is as follows:
17.2.1 Repeatability - The difference between successive 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 in only one case in twenty:
17.2.2 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 in only one case in twenty:
