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 Generate. 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 Field calibration service is available for this calibration. Please note the actual measurement uncertainties
achievable on a customer's site can normally be expected to be larger than the CMC found on the A2LA
Scope. Allowance must be made for aspects such as the environment at the place of calibration and for
other possible adverse effects such as those caused by transportation of the calibration equipment. The usual
allowance for the actual uncertainty introduced by the item being calibrated, (e.g. resolution) must also be
considered and this, on its own, could result in the actual measurement uncertainty achievable on a
customer’s site being larger than the CMC. Field environmental conditions are limited to (15 to 30) °C
and < 80 % Relative Humidity to 30 °C.
4 In the statement of CMC, percentages are percentages of reading, unless otherwise indicated.
5 In the statement of CMC, L is the numerical value of the nominal length of the device measured in
Inches
6 This Laboratory also has a Mobile Laboratory that can perform field calibrations for the noted calibrations.
7 This scope meets A2LA’s P112 Flexible Scope Policy.
8 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. | ||

Ranges are reproduced from the accredited scope document as published, and only where we found that range printed in the document for the line. Otherwise the cell reads “See scope document”. An absent range means the register did not state one. Line numbers are ours, for cross-reference; they follow the order of the scope document.
