A2LA Accreditation

The American Association for Laboratory Accreditation (A2LA) is a nonprofit, non-governmental, public service, membership society. The mission of A2LA is to provide comprehensive services in laboratory accreditation and laboratory-related training. Laboratories are accredited in the following fields: Acoustics & Vibration, Biological, Calibration, Chemical, Construction Materials, Electrical, Environmental, Geotechnical, Mechanical, Nondestructive, and Thermal. In addition to these broad fields, specifically-tailored programs are available for animal drugs, automotive electromagnetic compatibility (EMC), environmental lead (Pb), fertilizers, food testing, and putting green materials testing. Aldinger's scope identifies the specific testing or calibration capabilities for which we are accredited.

1 This laboratory offers commercial calibration service and field 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. Calibration and Measurement Capabilities 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 and this laboratory meets A2LA R104 – General Requirements: Accreditation of Field Testing and Field Calibration Laboratories for these calibrations. 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, repeatability) 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.

4 In the statement of CMC, L is the numerical value of the nominal length of the device measured in inches and R is the numerical value of the resolution of the device in microinches unless otherwise noted.

5 The CMC stated for calibrations performed in the laboratory is applicable for calibrations performed in the field.

6 CMC for the Wavetek 9100A is based on 1-year specifications within a temperature range of 23 °C ± 5 °C. Field calibrations will be performed within 23 °C ± 5 °C.

7 CMC for the HP 34401 is based on 1-year specifications within a temperature range of 18 °C to 28 °C. Field calibrations will be performed within 18 °C to 28 °C, 30 % to 55 % humidity.

8 Where ranges are not specified, the CMC stated is for the cardinal points only.
