1. The CMC (Calibration and Measurement Capability) stated for calibrations included on this scope of
accreditation represents the smallest measurement uncertainty attainable by the laboratory when performing
a more or less routine calibration of a nearly ideal device under nearly ideal conditions. It is typically
expressed at a confidence level of 95 % using a coverage factor k (usually equal to 2). The actual measurement
uncertainty associated with a specific calibration performed by the laboratory will typically be larger than
the CMC for the same calibration since capability and performance of the device being calibrated and the
conditions related to the calibration may reasonably be expected to deviate from ideal to some degree.
2. The laboratories range of calibration capability for all disciplines for which they are accredited is the interval
from the smallest calibrated standard to the largest calibrated standard used in performing the calibration.
The low end of this range must be an attainable value for which the laboratory has or has access to the
standard referenced. Verification of an indicated value of zero in the absence of a standard is common practice
in the procedure for many calibrations but by its definition it does not constitute calibration of zero capacity.
3. The presence of a superscript F means that the laboratory performs calibration of the indicated parameter at
its fixed location. Example: Outside MicrometerF would mean that the laboratory performs this calibration
at its fixed location.
4. The presence of a superscript O means that the laboratory performs calibration of the indicated parameter
onsite at customer locations. Example: Outside MicrometerO would mean that the laboratory performs this
calibration onsite at the customer’s location.
5. The presence of a superscript FO means that the laboratory performs calibration of the indicated parameter
both at its fixed location and onsite at customer locations. Example: Outside MicrometerFO would mean that
the laboratory performs this calibration at its fixed location and onsite at customer locations.
6. Measurement uncertainties obtained for calibrations performed at customer sites can be expected to be larger
than the measurement uncertainties obtained at the laboratories fixed location for similar calibrations. This
is due to the effects of transportation of the standards and equipment and upon environmental conditions at
the customer site which are typically not controlled as closely as at the laboratories fixed location.
7. The term L represents length in inches or millimeters as appropriate to the uncertainty statement.
8. The term P represents pressure in units appropriate to the uncertainty statement.
9. The term Wt represents weight in pounds or grams (including SI multiple and submultiple units) appropriate
to the uncertainty statement.
