Testing and calibration facilities for customer orders

It is possible to carry out measurements as are required for sound field description in accordance with
- IEC 61157 (diagnostic devices) and
- IEC 61689 (therapy equipment).

Acoustic measurements in accordance with
- IEC 60601-2-37 and
- FDA 510(k)
can also be performed.

In detail, our current measuring capabilities for customer orders comprise:

Ultrasound power measurements (radiation force balance), 0.75 MHz - 25 MHz
Calibration of ultrasound wattmeters
Calibration of hydrophones, 0.5 MHz - 50 MHz
Sound pressure measurements (hydrophone field measurements),
1 MHz - 15 MHz
Measurement of derived local intensity (hydrophone field measurements),
1 MHz - 15 MHz
Determination of ultrasound beam dimensions (hydrophone field measurements),
1 MHz - 15 MHz
Calculation of additional sound field parameters
Measurement of technical ultrasound fields, 20 kHz - 500 kHz
Power measurements of high intensity therapeutic ultrasound fields (HITU), up to 500 W, 0,75 MHz - 5 MHz

The costs for all orders will be charged in accordance with the Official Regulations Governing Charges for Services Rendered by PTB and according to the amount of work actually arising.
