Electrical and Electronics EMC (Electromagnetic Compatibility) Testing

Your Local Partner for Access to Global Markets

Liiketoimintahaaste

The pressure to bring new products to market faster, within a reduced budget and with higher quality has never been greater. And keeping R&D projects on schedule, within budget, all with less support staff available is a constant battle. Electromagnetic Compatibility (EMC) is a phenomena that must first be understood, and secondly complied with and is a requirement for most Electrical and Electronic products and most markets worldwide. Non-compliant products risk being recalled or stopped at customs, negatively impacting upon brand image. Ensuring EMC Compliance for your products, systems and/or workplace is critical in order to meet your sales targets.

What is EMC Testing? EMC is the study of the unintentional generation and reception of electromagnetic energy with a goal being the correct operation, in the same environment, of different electrical and electronic equipment which involve electromagnetic phenomena in their operation. EMC Emissions is related to the reduction in the unintentional generation of electromagnetic energy, EMC Susceptibility or Immunity refers to the correct operation of electrical and electronic equipment in the presence of electromagnetic disturbances. There are various terminoligies within the field of EMC it is worth understanding:

  • EMC Emissions Testing - A test to measure the electromagnetic interference (EMI) caused by an electrical device
  • EMC Immunity Testing - A test to measure the susceptibility of a product to electromagnetic interference from other sources
  • Electrostatic Discharge (ESD) - the release of static electricity when two objects come into contact. Examples of ESD includes the static electricity you sometimes feel after drying clothes in a clothes dryer or a lightening bolt.
  • Conducted Immunity Testing - the injecting of current into the input and output cables of a system or product under test
  • Conducted Emissions Testing - the radio frequency energy that is transmitted from an electrical device through the power cord and back into the electrical system
  • Intentional Radiator - A product that intentionally generates and emits radio frequency energy such as a radio device like a cell phone
  • Non-intentional Radiator - A device that is not intended to emit radio frequency energy, but generates radio frequency energy for use within itself or that sends radio frequency signals to equipment via connecting wires such as a personal computer or television
  • Radio Frequency - A frequency at which electromagnetic radiation of energy is useful for communications
  • Radio Frequency Compatibility - the ability of antenna-connected RF receiver / transmitter subsystems, operating within a system, to function properly without performance degradation caused by antenna-to-antenna coupling
What are the key benefits?
  • Demonstrate by way of an independent test report to your clients and authorities that your product is compliant with EMC regulations
  • EMC consultants can advise on designing compliance into your future products
  • Save on investing heavily in EMC test equipment, calibration, accreditations and staffing by outsourcing to a global leader in compliance solutions

Usein kysyttyä

  • Do I need to perform EMC testing on my product?

    There may or may not be a regulatory requirement for testing dependent upon your target market, however, carrying out EMC testing provides you with evidence that your product complies with the relevant EMC regulations and directive(s). After a successful test program, you can be confident that your product reliability will be increased, reducing warranty issues and servicing costs. Testing also highlights potential issues or problems with the product, and can be fixed before production. Testing is a long term investment. Field reliability encourages customers to stay loyal to your product when considering replacement or expansion, and can reduce warranty issues which in turn can increase profits

  • In Europe, does CE + CE = CE?

    Combining CE marked sub-assemblies and components into a final product does not guarantee EMC compliance of the finished product as there could be some interference when the components or sub-assemblies operate together.
