Messgeräte reparieren: Zulassung als Instandsetzer

Anyone wishing to repair measuring devices requires an approval.

During calibration, a tested measuring device that complies with the legal requirements is marked as calibrated by a calibration mark and protected against tampering by a security stamp. Depending on the type of measuring device, the calibration period (duration of validity of the calibration) varies between 6 months and several years, sometimes indefinitely. New measuring devices placed on the market correspond to calibrated measuring devices and do not require calibration for the duration of the first calibration period.

At their request, the competent authority may authorize companies that repair or refurbish calibrated measuring instruments or measuring instruments equivalent to calibrated measuring instruments (refurbishers) to identify refurbished measuring instruments with a special mark (refurbisher mark). Only measuring instruments marked in this way may continue to be used in compliance with calibration law after a repair with a security stamp violation.

Authorization is granted upon application. In particular, expertise must be taken into account in the assessment. The following is sufficient proof for persons carrying out repairs

• successful completion of vocational training in a technical field or
• at least one year's experience in the field of maintenance or repair in a technical area.

Knowledge of calibration law/calibration technology is also required. Repair personnel for electronic equipment must be trained by the manufacturer or a sales partner authorized by the manufacturer for specific measuring devices.

The application must specify the types of measuring instruments for which the repair authorization is requested.

As documents may be required to prove that the above requirements have been met, it is recommended that you contact the responsible office in advance.

Fees are charged according to the calibration costs ordinance. Detailed information can be obtained from the Verification Directorate North.
