11.1 Calculate the water in the sample, as weight or volume percent, in accordance with the basis on which the sample was taken, as follows:
12. Report
12.1 Report the results as the water content to the nearest 0.05% if the 2-mL receiver has been used and to the nearest 0.1% if the 10-mL or 25-mL receiver has been used and to the nearest subdivision if a 5-mL receiver has been used with a 100-mL or 100-g sample.
13. Precision and Bias
13.1 Precision - The criteria described in 13.1.1 and 13.1.2 should be used to judge the acceptability of results when using the 10 or 25-mL traps. The precision when using the 2-mL trap or a 5–mL trap has not been established.
NOTE 5 - Practice D6300 was not used in obtaining precision data.
13.1.1 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, in the normal and correct operation of the test method, exceed the values in Table 4 in only one case in twenty.
13.1.2 Reproducibility - The difference between two single and independent test 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 values in Table 4 in only one case in twenty.
13.2 Bias - As there is no accepted reference material suitable for determining bias for the procedure described in this test method for measuring water in petroleum products and bituminous materials by distillation, no statement about bias is made.
