EMC and the European market

The definition of Electromagnetic Compatibility as provided in the UK Defence Standard 59-41 is;

“Electromagnetic compatibility is an essential feature of any specification for electrical equipment and is defined as the ability of electrical and electronic equipment’s, sub-systems and systems to share the electromagnetic spectrum and perform their desired functions without unacceptable degradation from or to the specified electromagnetic environment”

European Standards for non-military equipment now exist which strictly govern the permissible levels of radiated and conducted interference, for both emissions and susceptibility. Once certified, electronic equipment, sub- assemblies and, where applicable, components may now display the ‘CE’ Mark indicating that they are in compliance with the EC Directive on Electromagnetic Compatibility (EMC) 89/336/EEC, as amended by Directive 92/331/EEC. There are currently as many facets to compliance as there are publications giving both theoretical and practical help to manufactures. It has therefore been decided for simplicity to avoid offering in this brochure, further in-depth advice to manufactures regarding EMC compliance and to concentrate our efforts on the manufacture and supply of a comprehensive range of shielding material designed to combat radiated interference. It should be noted, however, that Nolato do offer complimentary advice to electronics manufactures on the design and application of shielding materials and will be pleased to visit a potential customer in order to discuss the shielding requirements if specific projects. In many cases this can involve providing samples in addition to advice.
