KARL DEUTSCH equipment for non-destructive materials testing is developed and manufactured with much passion for detail so we are able to offer our customers the best solution for their testing tasks. However, when delivering a device to the customer, our job does not end there.

Our application laboratory (alab@karldeutsch.de) and our service division (service@karldeutsch.de) are available as competent contact partners for application-related questions, problems in handling the devices and in the event of repairs.

The standards for ultrasonic testing equipment are compulsory for us as a manufacturer: Ultrasonic testing equipment should be inspected before delivery, in regular intervals of twelve months and after repairs.

For conventional ultrasonic test equipment, the new standard DIN EN ISO 22232-1 was released in September 2021. In addition to standardised documentation, it requires a type test (Group 1 tests). In addition, each individual instrument must be tested (Group 2 tests).

Within the scope of this inspection, all essential properties of the transmitter pulse and the receiver circuitry are measured. Our customers thus have the certainty that their instruments also meet all relevant technical requirements.

However, carrying out the check is very demanding. For example, in addition to high-quality electronic equipment, the standard requires the measurement of at least 24 characteristic values of the transmitter pulse. Even more extensive are the measurements to check the receiver characteristics. For each available filter setting, typically 150 – 200 individual measurements are recorded.

At KARL DEUTSCH, we have implemented the standard requirements in our PEAT automated testing setup. PEAT remotely controls the unit to be tested as well as high-quality measuring instruments, and records all measured values required in the Group 2 tests. Our well-trained staff carries out all other testing tasks, e.g. checking the physical condition and external appearance of the equipment as well as checking other equipment features and accessories. Minor damage is repaired directly and without further notice. In addition, the units are provided with the latest operating software.

So far, we have been able to implement the PEAT automated testing procedure for the following ECHOGRAPH units: ECHOGRAPH 1090, ECHOGRAPH 1095 and ECHOGRAPH 1170.

For devices that were delivered in conformity with the previous standard DIN EN 12668-1, adjustments may be necessary in order to comply in full with the requirements of the new standard.
