Notes
1. Frequency response determined by IEC 61094-5: M ethods for pressure calibration of working standard microphones
by comparison.
2. Calibration of reference equipment is traceable to one or more of the following National Labs: NIST, PTB or DFM .
3. Calibration is performed in compliance with ISO 9001, ISO 10012-1 and ANSI/NCSL Z540.3.
4. Due to state-of-the-art limitations, 4:1 calibration ratios are not possible on pressure measurement standards, microphones
and acoustic calibrators. Calibration ratios for these types of devices are limited to 1:1.
5. See M anufacturer’s Specification Sheet for a detailed listing of performance specifications.
6. This certificate shall not be reproduced, except in full, without written approval from PCB Piezotronics, Inc
7. Calibrated per ACS-21.
