Since June 2015, a new standard for characterizing and verifying multi-stage ultrasound control devices has come into effect: ISO 18563-1:2015.
The procedures for multi-elements-specific measures are presented and detailed below:
- visual inspection of all the components of the case, which is accompanied by a systematic cleaning of the inside and outside of the case when it is in periodic verification.
- measurements of ascent time, width and pulse amplitude that can characterize the quality of the transmitters and their settings.
- the linearity measurement of the time base of transmitters and receivers that validates the accuracy of the delays that M2M applies to each ultrasonic shot of each track as well as to each receiver and therefore the resulting laws.
- The bandwidth measurement that guarantees the range of frequencies for which M2M devices are intended to work.
- The amplitude lane comparison measure that ensures a minimum dispersion of responses between each receiver.
- the input-equivalent noise measurement that ensures a negligible level of electronic disruption compared to disruption due to the work environment.
- gain linearity measurements and vertical display that ensure the accuracy of signal amplification levels.
As required by the standard, M2M performs these measurements on all transmitters and receivers of the devices. All of these measures are part of the periodic Group 2 tests of standard 18563-1. M2M also applies on demand for aeronautics, the TITM6-0016 Issue 4 table 7 methods 1 for which the company also performs reverberation and temporal resolution measurements.
