Accelerometer calibration

Accredited calibration

An accredited certificate will be accepted without discussion from your customers or auditing authorities. Brüel & Kjær can provide the following types of accreditations for Brüel & Kjær accelerometers:

• DANAK (English certificate)
• A2LA (English certificate)
• DAkkS (German certificate)
• NATA (English certificate)

Initial calibration

To start the accredited calibration history from day one, we recommend that you take advantage of our accredited-calibration services when you purchase your new accelerometer.

Re-calibration

Brüel & Kjær recommends annual re-calibration to provide data for an unbroken calibration history to use as a reference, either for internal requirements, for auditing required by authorities or at the request of your customers. The shorter the period between calibrations, the lower the risk of questionable measurements.

Measurements

Calibration of accelerometers is performed in the range 1 Hz to 20 kHz

Measurements are conducted according to IEC 16063 and to the manufacturer’s specifications

Measurements are traceable to institutions such as NIST and PTB

With the accredited certificate, you get:

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