Calibration of Calibrators

For Sound Calibrator, Pistonphone and Vibration Calibrator 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. Usual recommendation is annual calibration.

Brüel & Kjær can provide these types of accreditations for Brüel & Kjær Calibrators:

• DANAK (English certificate)
• A2LA (English certificate)
• UKAS (English certificate)
• DKD (German certificate)
• RvA (Dutch certificate)
• ENAC (Spanish certificate)
• NATA (English certificate)
• Inmetro (Portugese certificate)

Initial Calibration

To start the calibration history from day one, we recommend you order accredited calibration together with your new Calibrator or Pistonphone.

Regular 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 regularly. Brüel & Kjær recommends annual calibration.

Measurements

• Measurements of Sound Calibrator and Pistonphone are according to standard IEC 60942
• Sound Calibrator is measured at specified frequencies
• Pistonphone is measured at 250 Hz
• Vibration Calibrator is measured at 159.2 Hz. Vibration level, frequency and distortion are measured

Measurements are traceable to, for example, DPLA, NIST, NPL and PTB.

Certificate

With the accredited certificate you get:

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

Traceable Calibration

Measurements

• Measurements of Sound Calibrator and Pistonphone are according to standard IEC 60942
• Sound Calibrator is measured at specified frequencies
• Pistonphone is measured at 250 Hz
• Vibration Calibrator is measured at 159.2 Hz. Vibration level, frequency and distortion are measured
