In 2021, the standard DIN EN 12668-1 (Characterisation and verification of ultrasonic equipment) applicable to portable ultrasonic equipment was withdrawn and replaced by the new standard DIN EN ISO 22232-1.

Since then, all new ECHOGRAPH 1095 ultrasonic flaw detectors have been delivered with certificates in accordance with the new standard. For periodic inspections of older ECHOGRAPH instruments such as the 1090, it should be noted that many measurement methods for inspection of the devices have been changed in the new standard. The test criterion for the receiver amplifier has been tightened in the new standard. Due to this, a new calibration of the ultrasonic receiver is often necessary for the ECHOGRAPH 1090 model. The additional calibration is only necessary for the initial test according to DIN EN ISO 22232-1, and thus the moderate costs for the adjustment only occur once. If an exchange of the main board is necessary, it will be discussed with the customer whether this should be done or whether a device exchange to a new, modern ECHOGRAPH 1095 with an attractive exchange discount would make more sense. At the customer‘s request, it is still possible to issue a certificate according to the old (no longer valid) standard DIN EN 12668-1.
