11. Report
11.1 The report shall include the following:
11.1.1 Average burning rate of the sample to the nearest 1 g/h.
11.1.2 Initial dimensions of the flame to the nearest 1 mm.
11.1.3 Final dimensions of the flame to the nearest 1 mm.
11.1.4 Density of the chimney deposit (none, light, medium, or heavy) and its color (none, white, yellow, or brown).
12. Precision and Bias
12.1 The precision of the test method as determined by statistical examination of interlaboratory results is as follows:
12.1.1 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:
where:
X = average of two test results.
12.1.2 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:
where:
X = average of two test results.
12.2 Bias - a program to obtain additional data for precision and bias is under discussion. When developed, the additional data will be included.
