9. Report
9.1 Report the completed test on the corrugated board as follows: total wax content, g/m2, or total wax content, %.
10. Precision and Bias
10.1 Precision - The precision of this test method as determined by statistical examination of interlaboratory results is as follows:
10.1.1 Repeatability - The difference between two 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 only in one case in twenty:
5 % of the mean
10.1.2 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 the following values only in one case in twenty:
12 % of the mean
NOTE 6 - Precision was determined in an interlaboratory study on the following samples:
10.2 Bias - The procedure in this test method has no bias because the total wax content of corrugated paper and paperboard can be defined only in terms of a test method.
