ASTM D3708 Standard Test Method for Weight of Wax Applied During Curtain Coating Operation
10. Report
10.1 Report the weight of wax (average of duplicate specimens) in grams per square metre (lb/1000 ft2) as the total wax applied by a curtain coater.
11. Precision
11.1 The precision of this test method as determined by statistical examination of interlaboratory results is as follows:
11.1.1 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 10 % of the mean only in one case in twenty.
NOTE 5 - The repeatability data were obtained on test blanks to which wax was applied by a curtain coater at 35 g/m2 (7 lb/1000 ft2).
11.1.2 Reproducibility - Not applicable.
11.2 Bias - The procedure in this test method has no bias because the value of weight of wax applied can be defined only in terms of a test method.
