Repeatability is the precision obtained under repeatability conditions.
Repeatability is the closeness of the agreement between the results of independent measurements of the same analyte carried out subject to all of the following conditions:  the same method of measurement, the same observer, the same measuring instrument, the same  location, the same conditions of use, repetition over a short period of time. Independent measurements are made on distinct subsamples of a test material. If  possible, at least 8 measurements should be performed.  Repeatability is a characteristic of a method not of a result.
