This laboratory offers commercial calibration service.
2
Calibration and Measurement Capability Uncertainty (CMC) is the smallest uncertainty of measurement
that a laboratory can achieve within its scope of accreditation when performing more or less routine
calibrations of nearly ideal measurement standards or nearly ideal measuring equipment. 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
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.
4
Uncertainty components that can be reasonably attributed to the Unit Under Test have not been utilized in
the calculation of the CMC value for this measurement parameter.
5
This scope meets A2LA’s P112 Flexible Scope Policy.
6
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.
