Calibration Laboratory Sound and Vibrations

AV-Consulting Calibration Laboratory is independent calibration laboratory for sound and vibrations. Our commitment is to provide the highest level of calibration and testing services in compliance with the governing standards of this industry and ISO-17025 and demonstrate compliance by third party accreditation through, client audits, internal audits, management reviews and an effective corrective action system. It is laboratory management’s commitment to maintain good laboratory practices and good professional practice of our testing and calibration services to our clients. It is the policy of the laboratory that test, calibrations and services shall always be carried out in accordance with stated standardized methods and/or our client’s requirements. It is a requirement that all staff concerned with test and calibration activities within the laboratory familiarizes themselves with the quality documentation and implement these policies and procedures. Our Calibration and Measurement Capability can be found in the table below. CMC: Calibration and Measurement Capability is the smallest uncertainty of measurement the laboratory can provide to its customers, expressed as the expanded uncertainty having a coverage probability of approximately 95%. The expanded uncertainty U, is calculated according to EA-4/02 "Expression of the Uncertainty of Measurement in Calibration".

Notes regarding our CMC:

1. CMC: Calibration and Measurement Capability is the smallest uncertainty of measurement the laboratory can provide to its customers, expressed as the expanded uncertainty having a coverage probability of approximately 95%. The expanded uncertainty U, is calculated according to EA-4/02 "Expression of the Uncertainty of Measurement in Calibration".
2. Calibration and Measurement in accordance with IEC-61672-3 are made in our lab under reference environmental conditions for periodic testing within the following ranges of environmental conditions: 80 kPa to 105 kPa for static air pressure, 20 ˚C to 26 ˚C for air temperature and 25% to 70% relative humidity.
3. Calibration and Measurement in accordance with IEC-60942-3 are made in our lab under reference environmental conditions for periodic testing within the following ranges of environmental conditions: 97 kPa to 105 kPa for static air pressure, 20 ˚C to 26 ˚C for air temperature and 40% to 65% relative humidity.
4. Reference environmental conditions for specifying the performance of sound level meters and sound calibrators are : 101,325 kPa for static air pressure, 23 ˚C for air temperature and 50% relative humidity.
5. Unless otherwise specified, uncertainties are given at actual laboratory environmental conditions.
6. Calibration and Measurement are only carried out within our laboratory.
7. Calibration and Measurement and Accept / Tolerance limits according to the latest standards of IEC-61672, IEC-60942, IEC-61260, ISO-16063-21, DIN 45669-1.
8. Calibration of 1ˮ, ½ˮen ¼ˮmicrophones.
9. Sound pressure is measured in a coupler.
10. The Free-field and Diffuse Field Responses characteristics of microphones are calculated using the measured actuator/pressure response and the correction coefficients provided by the manufacturer of the tested microphone.
11. Values listed with percent (%) are percent of reading of generated values.
12. IEPE stands for "Integrated Electronics Piezo Electric". Other proprietary names for the same principle are ICP®, CCLD®, Isotron®, Deltatron®, Piezotron® .
13. The generally applied calibration frequencies are Nominal Frequencies. The Exact Frequencies are in accordance with ISO 266 and equal to 10n/10 Hz, where n is an integer. Intermediate values are obtained by interpolation.
