Ifnecessary, mix the sample by hand or mechanical stirrer untilhomogeneous and deaerate.7.2 Tare three aluminum dishes to the nearest 0.1 mg.7.3 Add the plastisol or organosol specime

16、n in such amanner as to entirely cover the bottom of the dish. The weightadded to each dish shall vary by only 60.1 g of the selectedweight. If the thickness of the final product cannot be accu-rately determined, add 6.0 6 0.1 g to each dish.NOTE 2A more representative measurement of weight loss is

17、possibleif the thickness of the sample in the aluminum dish approaches thethickness of the material during processing. The weight of the specimensadded to the dish is allowed to vary according to the application.7.4 Reweigh the dishes to the nearest 0.1 mg.7.5 Place only three dishes from a single s

Precision and Bias10

23、.1 The precision of this test method is based on anintralaboratory study of ASTM D6150, Standard Test Methodfor Estimating Processing Losses of Plastisols and OrganosolsDue to Volatility, conducted in 1996. Six laboratories partici-pated in this study, testing three specific masses (3 gm, 6 gm,and 9

24、 gm) of thirteen different formulations. Every “test result”represents an individual determination. The laboratories re-ported a single test results for each material. Except for the lackof reported replicates, Practice E691 was followed for thedesign and analysis of the data; the details are given

25、in anASTM Research Report.310.1.1 Repeatability (r)The difference between repetitiveresults obtained by the same operator in a given laboratoryapplying the same test method with the same apparatus underconstant operating conditions on identical test material withinshort intervals of time would in th

26、e long run, in the normal andcorrect operation of the test method, exceed the followingvalues only in one case in 20.10.1.1.1 Repeatability can be interpreted as maximum dif-ference between two results, obtained under repeatabilityconditions, that is accepted as plausible due to random causesunder n

27、ormal and correct operation of the test method.10.1.1.2 Repeatability limits cannot be determined withoutreplicate test results from the participating laboratories.10.1.2 Reproducibility (R)The difference between twosingle and independent results obtained by different operatorsapplying the same test

28、 method in different laboratories usingdifferent apparatus on identical test material would, in the longrun, in the normal and correct operation of the test method,exceed the following values only in one case in 20.10.1.2.1 Reproducibility can be interpreted as maximumdifference between two results,

29、 obtained under reproducibilityconditions, that is accepted as plausible due to random causesunder normal and correct operation of the test method.10.1.2.2 The average Reproducibility limit determined fromall reported data is 0.019 grams.10.1.3 The above terms (repeatability limit and reproduc-ibili

30、ty limit) are used as specified in Practice E177.10.1.4 Any judgment in accordance with 10.1.1 wouldnormally have an approximate 95 % probability of beingcorrect, however the precision statistics obtained in this ILSmust not be treated as exact mathematical quantities which areapplicable to all circ

31、umstances and uses. The lack of reportedreplicate results essentially guarantees that there will be timeswhen differences greater than predicted by the ILS results willarise, sometimes with considerably greater or smaller fre-quency than the 95 % probability limit would imply. Considerthe reproducib

32、ility limit as a general guide, and the associatedprobability of 95 % as only a rough indicator of what can beexpected.3Supporting data have been filed at ASTM International Headquarters and maybe obtained by requesting Research Report RR:D20-1265.
