Sound Level Meters are calibrated to the requirements in the standards they are designed to: IEC 61672, IEC 60651/ 60804, BS 7580, ANSI S1 4, and/or ANSI S1.43.
In addition to standard Sound Level Meter calibrations, HBK has approved service centers for calibration to meet national, legal requirements.
Also, 1/1-octave and 1/3-octave filter calibrations according to IEC 61260 are available for the frequency range from 6.3 Hz to 20 kHz.
For sound level meters, Brüel & Kjær provides two primary calibration services: accredited calibration and traceable calibration. These services include verification for selected countries and instrument verification.
Professional Sound Level Meter calibration is a prerequisite for assuring the quality of your measurement results in the long term. Moreover, torque sensor calibration is an integral part of your ISO9001 certification.
Accredited calibration primarily fulfills requirements for legal purposes. Brüel & Kjær can provide the following accreditation for our sound level meters:
We recommend you order accredited calibration together with your new sound level meter, to start your calibration history from the very first day.
Re-calibration and measurementBrüel & Kjær recommends annual re-calibration to provide data for an unbroken calibration history. This can then be used as a reference for internal requirements, for auditing required by authorities, or at the request of your customers.
Measurements of sound level meters are according to standards IEC 61672, IEC 60651/ 60804, BS 7580, ANSI S1 4, and ANSI S1.43. Initial calibrations on new sound level meters Types 2250, 2250 Light and 2270 will be performed according to IEC 61672. This applies for calibration according to accreditation bodies DANAK and ENAC.
Re-calibration of Types 2250, 2250 Light and 2270 for DANAK and ENAC will be performed to the latest standard, IEC 61672, unless you specify another standard on the order.
Measurements are traceable to institutions such as DPLA, NIST, NPL and PTB.
Additional CalibrationThe certificate for accredited calibration gives you:
