CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific calibration. 3 In the statement of Range and CMC, OD = Optical Density (also called Absorbance) is a measure of the light-absorbing ability of an object, expressed as: OD λ = -log 10 (I/Io), where I is the transmitted light intensity at a specified wavelength λ that has passed through a sample, and Io is the incident light intensity of the light before it passes through the sample. 4 In the statement of Range, RFU is equal to rela tive fluorescent units and RLU is equal to relative luminescence units. 5 This scope meets A2LA’s P112 Flexible Scope Policy. 6 The type of instrument or material being calibra ted is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter.
