Laboratory for EMC tests of emitted interference and noise resistance

EMC Testing

Testing electromagnetic compatibility - according to international requirements in our EMC test laboratories

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.

Regulatory EMC Testing at CETECOM

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:

  • ETSI EN 301 489 – Various Parts – Electromagnetic Compatibility (EMC) standard for radio equipment and services
  • DIN EN 61326-1:2013-07 – Electrical equipment for measurement, control and laboratory use – EMC requirements – Part 1: General requirements (IEC 61326-1:2012);
  • DIN EN 61547:2010-03 – Equipment for general lighting purposes – EMC immunity requirements (IEC 61547:2009)

Customer-specific EMC Testing

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

  • Development accompanying EMC testing
  • Change tests
  • Quality assurance testing (mass production tests)
  • EMC evaluation
  • Evaluation of quality assurance
  • On-site measurements
  • Test plan generation/test plan strategy
  • EMC consulting services to clarify national, European and international laws, regulations and guidelines

Automotive EMC

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 (appendices 4-6 and 11-16). 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:

  • TL81000 (VW)
  • MBN 10384 (Mercedes Benz)
  • GS95002 (BMW)

EMC Testing for medical technology

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:

  • Medical Device Directive (93/42/EEC / 2007/42/EC)
  • Directive IEC 60601-1-2, 4th edition

Thus we can offer EMC test services for electrical medical devices.

EMC for industrial products / mechanical engineering

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

Technical equipment for conducting EMC 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:

  • Power generation plants
  • Energy transfer (overhead lines, also HVDC)
  • electrical machines and devices
  • Intentional radiocommunication equipment (radios, mobile radio base stations, radar stations, etc.)
  • Other field-emitting devices and installations

 

Our EMC laboratories

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:

  • Five 3m test chambers (Semi-Anechoic Chamber)
  • a 5m test chamber (Semi-Anechoic Chamber) for the measurement of vehicles, among other things
  • a 3m test chamber (Fully Anechoic Chamber)
  • an open area test site / OATS (Open Area Test Site – 10m)
In order to offer our customers the greatest possible capacity, shielded measuring cabins are also available for flexible use.

Expert knowledge EMC Testing

What is (electromagnetic) immunity?

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.

What does (electromagnetic) emitted interference or interference emission mean?

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.

When is EMC testing required?

EMC testing is essential to ensure the interference-free, safe and reliable operation of a product and to comply with legal regulations.

Which products are subjected to EMC testing?

All technical devices from the areas:

  • industrial engineering
  • Consumer electronics
  • Automotive Engineering
  • Aerospace
  • Military Technology
  • Medical Technology
  • Information Technology
