14. Reporting
14.1 Report the results to the nearest 0.1 mg/kg, and indicate that they were obtained using Test Method D3246.
15. Precision and Bias
15.1 The following criteria should be used for judging the acceptability of results:
15.1.1 Repeatability - The difference between successive test results, obtained by the same operator with the same apparatus under constant operating conditions on identical test material would, in the long run, and in the normal and correct operation of the test method, exceed the following values only in one case in twenty:
15.1.2 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, and in the normal and correct operation of the test method, exceed the following values only in one case in twenty:
15.2 Bias - The bias of the procedure of this test method cannot be determined since an appropriate standard reference material containing trace sulfur level in ethylene is not available.
