reproducibility
precision under reproducibility conditions
3.1.13
repeatability conditions
conditions wtiere independent test results are obtained with the same method on identical test items in the same laboratory by the same operator using the same equipment within short Intervals of lime
3.1.14
reproducibility conditions
conditions where test results are obtained with the same method on identical test items in different laboratones with different operators using different equipment
NOTE When different methods give test results that do not differ significantly, or when different methods are permitted by the design of the experiment (as in a proficiency study or a materiaI-certifcation study for the establishment of a consensus value of a reference material), the temi reproducibihtif may be applied to the resulting parameters. The conditions must be explicitly staled
3.1.15
repeatability standard deviation
standard deviation of test results obtaied under repeatability conditions
NOTE Repeatabibty standard deviation is a measure of the dispersion ci the distribution of test restits under repeatability conditions. Sinilarty repeatability vanance and “repeatability coefficient of variation” could be defined and used as measures of the dispersion of test results under rep.atability conditions,
3.1.16
reproducibility standard deviation
the standard deviation of test results obtained under reproducibility conditions
NOTE Reproducibility standard deviation is a measure of the dispersion of the distflbution of test results under repeatability conditions Similarty reproduclblkty variance’ and “reproducibility coefficient of variation” could be defied and used as measures of the dispersion of test results under reproducibility conditions.
3.1.17
repeatability limit
value less than or equal to which the absolute difference between two test results obtained under repeatability conditions may be expected to be with a probability of 95 %.
