We can carry out tests in accordance with other standards that refer to basic standards.

All EMC compatibility tests are preparatory for the verification of all necessary requirements for CE marking.

Equipment used during EMC electromagnetic compatibility tests


Radiated testing is carried out in a semi-anechoic chamber full compliance for 3 m dimension. Equipment and semi-anechoic chamber are calibrated in accordance with the reference standards CISPR 16. Tests according ETSI standards.

Management of the entire authorization process for standards FCC (Federal Communications Commission) rule 47 PART 15 and PART 18. Management of the authorization process FCC  according following procedures:

  • Verification
  • Declaration of Conformity
  • Certification

Support in filling out the relevant documentation.

Electromagnetic shielding testing: of the effectiveness of shielding of textiles, panels, gaskets, shelter and shielded rooms, cabinets, frames and subframes, varnishes etc. in accordance with following standards: MIL STD 285, IEEE 299, EN 50147-1, EN 61000-5-7, EN 61587-3. Advice on electromagnetic shieldings of shielded rooms and chambers.

Which companies is it addressed to


EMC compatibility testing is addressed to companies operating in the electrical and electronic sectors that need to test their products manufactured by themselves or imported from extra EU countries. Tests are carried out on civil, industrial, medical, audio/video and ITE (Information Technology Equipment) products.

Consequent actions


The tests allow to obtain feedbacks on conformity with regulatory requirements. In case of negative results, Tecnolab del Lago Maggiore Srl provides a step by step support helping the customer in the modification process necessary to comply with the regulatory requirements.
