EMC measurement service

SCHURTER maintains a team of EMC specialists that offers a comprehensive, professional measurement service for ensuring effective EMC control.

SCHURTER carries out the necessary preliminary tests of your electrical systems or equipment to determine immunity and emissions. We have four laboratories where we perform our testing services: two in Switzerland (Lucerne and Mendrisio), one in Germany (Endingen) and one in China (Shenzhen). These EMC Competence Centers are equipped with the required test equipment and EMC chambers for measuring conducted emissions. In addition, we work in close cooperation with accredited laboratories around the world.

On-site measurements

Upon request, we provide on-site interference-suppression services on your electrical equipment using our mobile measurement tools. SCHURTER offers a mobile measurement service with all the equipment needed to examine conducted emissions. In this way, various conformity tests can be performed on the systems or equipment to be examined directly on site, at the manufacturer's facility or where the equipment is in operation.

Measuring leakage currents

SCHURTER recommends measuring the leakage current for every newly installed machine during various operating states. For this purpose, we offer measurements with a leakage-current analysis system. Based on test results, we identify excessively high leakage currents as well as their causes and offer suitable corrective actions.


Legislative bodies have established protection requirements which dictate that manufacturers of electrical equipment must ensure EMC compliance through appropriate measures. The limits for interference immunity or emitted interference are established in standards. Within the past few years, these limits and conditions in various countries within Europe have been harmonized with the new EMC Directive 2004/108/EC.

SCHURTER carries out all tests as dictated by the requirements specified in the standards whereby emission tests are possible only in a laboratory (IEC 61000-4-3 and IEC 61000-4-6). If certain measurements are not feasible in our own laboratories we work with partners that can guarantee the same level of quality

Test report for CE conformity

Measurement results are recorded in an EMC test report that provides you with CE proof of conformity for conducted emissions.

Product sample service

To solve special customer tasks, we develop special filter solutions and offer samples including documentation.

Safety is our Business
