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, the so-called immunity to interference and the emitted interference of devices are tested in particular. Because international legislators as well as manufacturers and distributors themselves specify a wide range of limits for the immunity and emitted interference of technical equipment, EMC testing is essential for their market launch.
We carry out EMC testing on the basis of various internationally harmonized EMC standards. Our test reports are recognized by official bodies and regulatory authorities around the world. This applies among others to:
Our testing services cover many common EMC requirements. Among others, the following guidelines should be mentioned here:
In addition to the regulatory EMC testing, which is often necessary for the approval of your products, we also offer tailor-made EMC testing. This enables us to define and perform tailored EMC performance test procedures according to customer requirements. The tailored EMC test services include
We hold various accreditations to perform EMC testing on vehicles. CETECOM is, for example, appointed as technical service EMC. In addition, we have the corresponding E1 approval of the Kraftfahrt Bundesamt (KBA) for EMC test services according to UN-R 10 series of amendments 05 and 06 (appendices 7-10 and 17-22). In addition, we are also recognized for EMC test services by the authority in Luxembourg (SNCH) for E13.
Furthermore, we offer various EMC testing according to the specifications of car manufacturers. Among them:
We are accredited by the ZLG, the Central Authority of the Federal States for Health Protection with regard to Medicinal Products and Medical Devices, to perform EMC testing for technical medical devices.
Guidelines and standards in this context:
Thus we can offer EMC test services for electrical medical devices.
Directive 2006/42/EC (Machinery Directive) regulates a uniform level of protection for the prevention of accidents involving machinery and partly completed machinery when it is placed on the market. This also includes EMC testing, which we can carry out either in our EMC measuring halls or in the form of on-site tests.
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 EMC laboratories are equipped with high quality measurement equipment to perform various types of customized EMC testing and to define specific EMC performance test procedures according to customer requirements.
We check whether the specified EMC limits are met in our accredited laboratories in Germany (Essen and Duesseldorf) and the USA (Milpitas, Silicon Valley). We have a large number of measurement capacities to be able to implement your projects flexibly and promptly:
Our laboratories in Duesseldorf and 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 Duesseldorf 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 as a technical service (E1), among others for EMC. In our laboratories in Essen and Duesseldorf we perform test services for electromagnetic compatibility according to UN-R 10 series of amendments 05 and 06 (annexes 7-10 and 17-22).
With the help of the E13 recognition by the Luxembourg authority SNCH, we are also able to carry out EMC testing in the automotive sector in accordance with the requirements of the regulation UN ECE regulation R10, modification series 05.
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.
