Calibrator and pistonphone calibration

Calibrator and pistonphone calibration

On a calibrator or pistonphone it’s important that you have accredited calibration and that the instrument is calibrated regularly.

For sound calibrators, pistonphones and vibration calibrators, Brüel & Kjær can provide accredited calibration, traceable calibration, verification for selected countries and instrument verification. 

Accredited calibration

On a calibrator or pistonphone it’s important that you have accredited calibration and that the instrument is calibrated regularly. The usual recommendation is for annual calibration.

Brüel & Kjær can provide these types of accreditation for Brüel & Kjær calibrators:

  • DANAK (English certificate)
  • A2LA (English certificate) 
  • DAkkS (German certificate)
  • ENAC (Spanish certificate)
  • NATA (English certificate)
  • Inmetro, Brazil (Portuguese certificate)

Initial calibration

To start your calibration history from day one, we recommend that you order accredited calibration together with your new calibrator or pistonphone.

Re-calibration

The shorter the period between calibrations, the lower the risk of measurements being questioned. Since calibrators and pistonphones are used to measure other instruments, it’s important to calibrate them regularly. Brüel & Kjær recommends annual calibration.

Measurements

  • Measurements of sound calibrators and pistonphones are performed according to the standard IEC 60942
  • The sound calibrators are measured at specified frequencies
  • Pistonphones are measured at 250 Hz
  • Vibration calibrators are measured at 159.2 Hz. Vibration level, frequency and distortion are measured
  • Measurements are traceable to institutions such as DPLA, NIST, NPL and PTB

Certificate

With our accredited certificate you receive:

  • Proof that calibration has been performed according to the quality requirements in ISO 17025
  • Measured uncertainty
  • Internationally accepted certificate with the logo of the accreditation body
  • Calibration conditions: air temperature, air pressure and relative humidity

Traceable calibration

Measurements

  • Measurements of sound calibrators and pistonphones are conducted according to the standard IEC 60942
  • Sound calibrators are measured at specified frequencies
  • Pistonphones are measured at 250 Hz
  • Vibration calibrators are measured at 159.2 Hz. Vibration level, frequency and distortion are measured

Certificate

The certificate includes all measurement results.

Legal verification

Brüel & Kjær can provide legal verification for:

  • Customers in Spain: Primitiva
  • Customers in Austria: Eichung

Please note that instrument verification does not contain measurement results.

Verification/conformance testing

A conformance test certifies that the instrument has been tested, has passed all production tests, and complies with the manufacturer's published specifications. You will receive an official Certificate of Conformance.

Please note that instrument verification does not contain measurement results.
