We offer various calibration services. The following procedure indicates step-by-step how to calibrate your sound meter or calibrator at BG Calibration Laboratory.
CONTACT
If you would like to calibrate a sound level meter or calibrator, please complete the request form or contact us. See the contact page for our details. We will then discuss with you which calibration procedure is most suitable for your instrument.
QUOTATION
We work with standard prices and, if desired, we will provide a quotation in which the price agreements, terms and conditions are determined.
ASSIGNMENT
If you agree with the quotation or our telephone proposal, an order confirmation will be sent that you return to us for approval.
TRANSPORT
We will discuss with you how the measuring instrument to be calibrated will be delivered to us. By carrier, by courier or brought by yourself.
Before you send a measuring instrument to us for calibration, always include our email addressThis email address is being protected from spambots. You need JavaScript enabled to view it. and the track & trace number in your shipping order, so that we can track your instrument during shipment.
CALIBRATION
Upon receipt, we start the calibration procedure according to our quality management system.
FINISHING
We aim for a lead time of 3 working days excluding transport time. Sometimes it takes a day longer, sometimes it can be a day faster.
INSURED
Your measuring instrument is insured as long as it is in the possession of Bureau Geluid Calibration Laboratory.
YOU STAY INFORMED
If there is a delay during the calibration procedure for any reason, you will be notified immediately.
If any deviations are found during the calibration procedure, we will also contact you.
FINISHING
After completing the calibration procedure, we prepare the calibration report.
CALIBRATION REPORT
The sound meter or calibrator and the calibration report will be returned to you via a carrier selected by us, or you can collect the measuring instrument yourself.
Bureau Geluid has an ISO/IEC 17025 calibration laboratory accredited by the RvA (Dutch Accreditation Council).
We calibrate sound level meters, analyzers and calibrators from almost all major manufacturers (Cirrus, Cesva, Bruel & Kjaer, Rion, Svantek, 01 dB, Larson Davis, Norsonic, NTI, Embedded Acoustics) according to the following standards::
- ACCREDITED TEST AND CALIBRATION SOUND LEVEL METER ACCORDING TO STANDARD IEC-61672 PART 3
For a sound level meter that fully complies with the specifications of the IEC-61672 standard part 1, this is an accredited test and calibration according to the IEC-61672 standard part 3. An accredited calibration can in any case be carried out for sound level meters of various manufacturers with a type approval. - ACCREDITED TEST AND CALIBRATION ACCORDING TO STANDARD IEC-61260
Accredited testing / verification of the filter attenuation of octave band and third-band filters according to the IEC-61260 standard for a sound level meter with a spectrum analyzer function. - ACCREDITED TEST AND CALIBRATION ACCORDING TO STANDARD IEC-60942
For a single-signal and double-signal calibrator that fully complies with the specifications of the IEC-60942 standard, this is an accredited test and calibration according to the IEC-60942 standard. An accredited calibration can in any case be carried out for calibrators of various manufacturers with a type approval.
Traceable testing and verification
- STI MEASURING MODULE AND TALKBOX ACCORDING TO STANDARD IEC-60268
Traceable testing / verification of the STI measuring function and talk boxes. For various sound level meters with an STI measuring function for the measurement of speech intelligibility. This is not an accredited procedure. - TAPPING MACHINE FOR THE MEASUREMENT OF IMPACT SOUND INSULATION ACCORDING TO STANDARD ISO-140
The traceable testing/verification of a tapping machine. This is not an accredited procedure. - SOUND LEVEL METER ACCORDING TO STANDARD IEC-60651 OR IEC-60804
If it concerns an older sound level meter that complies with the older IEC-60651 standard, we perform a traceable test and/or traceable calibration. This is then not an accredited procedure. - TRACEABLE TEST
If the manufacturer of the instrument has not made any data necessary for the tests available, we will discuss the options with you. In any case, the test cannot be accredited, but it may be traceable. It could also be that we only perform an adjustment but not a test. This is then not an accredited procedure.
