36、 each package on strokes to prime and delivery rate. Identify any patterns or trends seen in the delivery ate ofthe packages during the test.11.2 Report the overall results of the testing and draw a conclusion as to the acceptability of the mechanical pump dispenser.If the mechanical pump dispenser

37、is acceptable, but with certain limitations, note accordingly.12. Precision and Bias12.1 PrecisionThe precision is highly dependent on the particular pump style and contents tested. One laboratory hasinvestigated one particular fine mist pump style and a hair spray product with six replicate tests p

38、er temperature variable, yieldingno visual product leakage, very minor cloggage, and all specimens retaining prime. For all specimens evaluated for strokes toprime, the test yielded an average of 6.58 strokes with a range of 6 to 7 strokes and a standard deviation of 0.53 strokes. For the23C specime

39、ns evaluated for output per stroke, the test yielded an average of 0.136 g with a range of 0.130 to 0.142 g and astandard deviation of 0.02 g. For the 45C specimens evaluated for output per stroke, the test yielded an average of 0.136 g witha range of 0.131 to 0.142 g and a standard deviation of 0.0

40、2 g. Other pumps and contents will have other averages and will havemore or less variability between replicate tests. Users of this test method practice are suggested to reference historical files ofprevious tests of similar pumps and contents for an estimate of within laboratory repeatability. The

41、Committee believes thatbecause of this strong product and pump style dependency, further investigation of repeatability and reproducibility is notpracticable.12.2 BiasThis test method practice has no bias because an accepted reference or referee value is not available.D6633 18313.
