Accuracy
Closeness of agreement between a test result and the accepted reference value (ISO 5725-1)
Repeatability
Precision under conditions where 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 time (ISO5725-1:1994)
