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 behavio r of the customer’s device and to influences from the circumstances of the specific calibration. 3 Salinity is a measure of the mass of dissolved salts (ionic constituents) in a given mass of solution and expressed as percentage (%). 4 This scope meets A2LA’s P112 Flexible Scope Policy. 5 The type of instrument or material being calibrated 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.
