2.7.3 Repeatability
Test a sample which meets repeatability requirement on the analyzer consecutively for 10 times,
calculate the CV(%) and absolute deviation (d) of each parameter, and the results shall meet the
requirements in the following table.
In the equation:
s
----standard deviation of sample test results;
x
----mean value of sample test results;
xi
----actual test result of the sample;
d
----absolute deviation of the sample test results.
