What this lab is accredited for
Our reading of the A2LA scope: each standard once, with its official name where we have checked it.
Only this lab. Searches the 1 standard number and the 1 official name we hold. When no standard matches, it searches the method text of every scope line.

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. | ||

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.
