Electromagnetic compatibility (EMC) refers to the ability of a technical device not to disturb other devices by electrical or electromagnetic effects or to be disturbed itself.
In an EMC test, primarily the so-called interference immunity and the interference emission of devices are checked. Because international legislators as well as manufacturers and distributors themselves specify the most varied limit values for the immunity to interference and emitted interference of technical devices, EMC tests are indispensable for their market launch.
Our EMC laboratories are equipped with high quality measurement equipment to perform different types of customized EMC tests
and to define specific EMC performance test procedures according to customer requirements.
We verify whether the specified EMC limits are met in our accredited laboratories in Essen (NRW) and the USA (Milpitas, Silicon Valley).
We have a large number of measurement capacities at our disposal in order to be able to implement your projects flexibly and promptly:
In order to offer our customers the highest possible capacity, flexible shielded measurement booths are also available.
Our EMC laboratories also has various additional facilities to test a wide range of different products with a wide range of characteristics:
We perform EMC testing based on various internationally harmonized EMC standards.
Our test reports are recognized by official bodies and regulatory authorities around the world.
In addition to regulatory radio tests for products with wireless technologies, EMC tests are also required for such products
so that they meet international standards and can be distributed in their target markets.
Here, a wide variety of specifications and limit values of the different regulatory approval regimes apply. We perform a variety of accredited EMC tests for products with wireless technologies and thus provide all services for market approval for devices with wireless technologies from a single source. This includes, among others, tests according to:
In the Electromagnetic Compatibility Act (EMVG), the legislator has made compliance with basic EMC requirements mandatory on the basis of EU Directive 2014/30/EU. For manufacturers, successful EMC testing in accordance with this directive also represents a key quality feature of their products, as it prevents product or system failures due to electromagnetic interference (EMI).
We test electrical equipment on the basis of our accreditations according to a variety of EMC standards. These include:
Electromagnetic compatibility testing in the automotive environment is also essential. Our diverse service portfolio for the automotive industry also includes EMC testing.
For example, our laboratory in Essen is designated as an EMC (and eCall) technical service and holds an E1 recognition from the German Federal Motor Transport Authority for EMC testing services in accordance with the UN-R 10 05 and 06 series of amendments (Annexes 7-10 and 17-22).
In addition, EMC tests according to various direct specifications of the automobile manufacturers round off our services. These include:
Testing of electromagnetic compatibility is important and mandatory, especially for electrical equipment used in medicine. The specifications of electromagnetic disturbances are strict, especially in the medical environment, and the results of the EMC tests must provide a reliable basis for the elimination of the disturbances.
Our EMC laboratory is accredited by the German Accreditation Body (DAkkS) with the involvement of the Central Office of the Federal States for Health Protection with regard to Medicinal Products and Medical Devices (ZLG) to perform EMC tests for technical medical devices. Thus, we offer EMC test services for electrical medical devices according to the Medical Device Directive (93/42/EEC / 2007/42/EC) and Directive IEC 60601-1-2, 4th edition.
Due to our accreditation we can issue test reports to you with DAkkS and ZLG logo – for a high traceability at the certification bodies.
Testing of electromagnetic compatibility of ticket vending machines, track and interlocking electronics, alarm systems, vehicle control electronics or sensors is conducted in our EMC laboratories according to the product standards of the EN 50121-x and EN 50155 series.
Directive 2006/42/EC (Machinery Directive) regulates a uniform level of protection for accident prevention for machines and partly completed machines when they are placed on the market. This also includes EMC tests, which we can perform either in our EMC test halls or in the form of on-site tests:
In addition to the regulatory EMC tests that are often required for approval of your products, we also offer customized EMC testing. This allows us to define and perform tailored EMC performance test procedures according to customer requirements. The customized EMC testing services include:
Electromagnetic environmental compatibility (also called electromagnetic compatibility to the environment, EMCE) refers to the compatibility of the immissions of electromagnetic fields (EMF) to the environment, especially to humans. It defines limit values to ensure safety and prevent possible damage to health.
In our tests we cover frequency ranges between 0 Hz and 6 GHz – in individual cases also higher frequencies – for EMCE measurements of electric fields. For magnetic fields, frequencies up to 250 MHz are recorded and evaluated.
Thus we test, for example:
Our laboratories in Essen are accredited by the DAkkS in accordance with DIN ISO 17025:2018 to perform a wide range of EMC testing.
Detailed information on the scope of accreditation for our EMC laboratories in Germany can be found on our accreditation overview.
Our laboratory in Essen is accredited by the DAkkS with the involvement of the ZLG to perform EMC tests for technical medical devices.
We are therefore authorised to carry out EMC testing on medical devices in accordance with the Medical Devices Directive (93/42/EEC / 2007/42/EC) and EN 60601-1-2:2015 and, as an accredited laboratory, to issue test reports with the DAkkS and ZLG labels.
Our know-how and competence in the field of automotive EMC is reflected in the designation of cetecom advanced as a technical service (E1), among others for EMC. In our laboratories in Essen we perform test services for electromagnetic compatibility according to UN-R 10 series of amendments 05 and 06 (annexes 7-10 and 17-22).
Our laboratory in the USA holds the DIN EN ISO 17025 accreditation of the A2LA for EMC services and can therefore also offer accredited test services in the field of EMC.
In high-frequency technology, it refers to the ability of a system to operate perfectly against an external source of interference up to a predefined level or setpoint. In the EMC measurement, a higher interference quantity is usually selected than that which occurs in practice – for later interference-free operation.
It is the technical term for the undesirable property of an electrical or electronic device to operate as a source of electromagnetic interference and thus to interfere with other devices. A distinction is made between conducted interference emission (also radio interference voltage) and field-bound interference emission (or radio interference radiation).
In test environments, tolerable emitted interference is defined by means of limit values – also in EMC testing.
If these are exceeded, measures for radio interference suppression are required. This is the case for most devices.
EMC testing is essential to ensure the interference-free, safe and reliable operation of a product and to comply with legal regulations.
