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.
