Our Services
Responsibility of public administration
As a competent and independent calibration centre, we perform a variety of official tasks in accordance with legal requirements. These include:
– Administration of batches and tests in statistical testing procedures
– Re-calibrations to ensure measurement accuracy
– Inspection of findings to clarify measurement deviations and complaints
Further services
In addition to our official tasks, we offer additional quality assurance services:
– Acceptance tests to ensure measurement accuracy before commissioning
Our processes are precise, efficient and meet the highest quality standards – for a secure and reliable measurement infrastructure.

Statistical Testing Procedures
The statistical testing procedure, described in Appendix 4 of EMmV, enables an efficient verification of the measurement accuracy of electricity meters without the need to remove each individual meter. Instead, the test is carried out on the basis of a representative sample.
Sequence of the testing procedure
Formation of a batch:
A batch comprises a maximum of 5,000 meters of the same type and year of manufacture.
Several users can be represented in a single batch.
Each user has the right to know which other parties are included in the same batch.
Inspection every five years:
A sample is inspected by a verification agency authorized by METAS.
If the sample passes the inspection, the validity of the verification of the entire batch is extended by five years.
If the sample does not fulfil the EMC requirements, all meters of the batch must be replaced.
Registration for the inspection procedure:
Registration for participation must be carried out by the end of June of the fourth year after the manufacture of the meter at a calibration centre.
This procedure ensures cost-efficient quality assurance without placing unnecessary burdens on the entire measurement infrastructure. This ensures the accuracy and reliability of electricity metering in the long term.
Acceptance Test
Safety and precision for measuring instruments
The quality of measuring instruments is crucial for accurate billing, legal compliance and long-term reliability. With the introduction of the European Measuring Instruments Directive (MID) on 30 October 2006, the approval and verification system in the EU member states was harmonized. However, the MID only regulates the marketing of measuring instruments – after the sale, national calibration law continues to apply.
Your responsibility as a measuring instrument user
While manufacturers are responsible for product quality, users of measuring instruments also bear a significant responsibility for the correctness of the measured values. Although one can rely on the manufacturer’s declaration of conformity, an additional quality acceptance test offers decisive advantages:
– Proof of product quality – you receive objective confirmation that the measuring instruments meet the agreed standards.
– Higher acceptance probability for sample inspections – Tested quality reduces the risk of subsequent failures or deviations.
– Additional security for buyers – A QAP ensures that the measuring instruments supplied meet the technical and legal requirements.
Individual and customized quality inspection
The quality acceptance inspection is based on a clearly defined agreement between the buyer and the supplier. Both legal requirements and individual quality requirements are considered. This means that you receive a customized inspection that is precisely tailored to your requirements.
Conclusion: A quality acceptance inspection protects against faulty measurement values, minimises risks and ensures maximum transparency – an investment in safety and precision.
