GB/T 27412-2012 Detection of laboratory bias using single test result from check standard
Abstract
This standard specifies the calculation of the inclusion interval between the single measurement result of the verification sample (CS sample) and the reference quantity value (RQV) when the laboratory detection method is assumed to be unbiased.
Note: This calculation is derived from the specified type I error rate, the period precision standard deviation (sR′) used in the detection method, the standard deviation of RQV (sRQV), the laboratory's assumption that the detection method is unbiased, and the estimation method of the probability that the single measurement result may fall outside the inclusion interval.
This standard applies to the normal model description and prediction of continuous numerical results produced by the measurement system under statistical control conditions.
