The quality of our expert consulting services can be best judged by the clients themselves. We spare no effort to ensure that you are entirely satisfied with our services.
We work according to a quality management system (QMS) which is subjected to periodic reviews and further development within internal audits. Because of the accreditation by the national accreditation body of the Federal Republic of Germany (DAkkS), our QMS also underlies an independent and external control institution.
We are accredited by DAkkS according to ISO/IEC 17025 (General requirements for the competence of testing and calibration laboratories).
The accreditation is valid for the scope of the module "Immission control, determination of vibrations", as specified in the accreditation certificate D-PL-20359-01-00.
The current accreditation certificate can be found here:
We are notified by the Ministry for Nature, Environment and Consumer Protection of the State North Rhine-Westphalia (LANUV) as an independent measuring institution
for the determination of vibration emissions and immissions according to § 29b BImSchG.
The notification is based on the current accreditation by DAkkS.
Prof. Dr. Heiland is a publicly appointed and sworn expert in the fields of Vibrations and Structural Dynamics.
Accuracy of Measuring Instruments
To secure high accuracy, we calibrate our measuring instruments every year. For that purpose we maintain our own testing apparatus. The calibration of our sensors is performed using a reference sensor whose metrological traceability is ensured by Deutscher Kalibrierdienst (DKD).
Regularly further training and attending specialist conferences is obligatory for our staff. As authors of various publications we participate in expert's discussions.
We are engaged in standards committees (such as DIN 4150, DIN 45669, DIN 45672, DIN 45673, VDI 2038). Therefore we gained a wide background knowledge as well as awareness of technical developments.
