6 sigma: Type of Test of Two Variances that compares variances of two or more populations that are not normally distributed.

ISO 3534-2:2006: r

repeatability critical difference for a specified probability of 95 %

ISO 3534-2:2006: R

reproducibility critical difference for a specified probability of 95 %

ISO 5725: La linéarité est la capacité d'une méthode d'analyse, à l'interieur d'un intervalle, à fournir une réponse proportionnelle à la quantité en analyte à doser dans l'échantillon pour le laboratoire.

ICH: It is the ability (within a given range) to obtain test results which are directly proportional to the concentration (amount) of analyte in the sample.

MSA: The correlation multiple and independent bias errors over the operating range. A system error component of the measurement system. The difference of bias throughout the espected operating (measurement) range of the equipment.

6 sigma: The Lower Control Limit (LCL) is a limit in the Control Chart that is set below the centerline, typically at -3 standard deviations, in order to determine whether or not the process is in control.

6 sigma: A Lower Specification Limit (LSL) is the lower limit of a tolerance range specified by a customer requirement. A measured value that is below this limit is considered a defect
