Electromagnetic Compatibility (EMC) - The ability of equipment or system to function satisfactorily in its electromagnetic environment without introducing intolerable electromagnetic disturbances to anything in that environment.
Remember: the latest terminology states that "electromagnetic disturbances" i.e. electromagnetic phenomena cause "interference" i.e. performance degradation of equipment.

Laboratory carries out electromagnetic compatibility testing in the range of accreditation (electrostatic discharge ESD immunity test, radiated radio-frequency field immunity test, disturbance field strength measurement, disturbance voltage measurement, harmonic current measurement, flicker measurement, EFT/burst immunity test, surge immunity testing, conducted disturbances immunity testing, voltage dips, short interruptions and voltage variations immunity test) and also interference power measurement according to undernamed standards:

EN 55022 "Limits and methods measurement of radio disturbance characteristics of information technology equipment",

PN-EN 55022 "Kompatybilność elektromagnetyczna. Dopuszczalne poziomy i metody pomiaru zakłóceń radioelektrycznych wytwarzanych przez urządzenia informatyczne (CISPR 22: 1993)"

EN 61000-4-2 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 2: Electrostatic discharge immunity test. Basic EMC Publication",

EN 61000-4-3 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 3: Radiated, radio - frequency, electromagnetic field immunity test".

EN 61000-4-4 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 4: Electrical fast transient/burst immunity test".

EN 61000-4-5 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 5: Surge immunity test".

EN 61000-4-6 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 6: Immunity to conducted disturbances, induced by radio-frequency fields"

EN 61000-4-11 "Electromagnetic compatibility (EMC) - Part 4: Testing and measurement techniques Section 11: Voltage dips, short interruptions and voltage variations immunity test"

ENV 50204 "Radiated electromagnetic field from digital radio telephones - immunity test"

EN 61000-3-2 ''Electromagnetic compatibility (EMC) - Part 3: Limits - Section 2: Limits for harmonic currents emissions (Equipment input current 16A per phase)"

EN 61000-3-3 ''Electromagnetic compatibility (EMC) - Part 3: Limits -Section 3: Limitation of voltage fluctuations and flicker in low-voltage supply systems for equipment with rated current 16A''

 

Above mentioned testing techniques are indispensable to achieve declaration of conformity with 89/336/EEC Electromagnetic Compatibility Directive which came into force from 01.01.1996. This means that everybody, who would like to sell his products within the market of the European Union has to perform tests according the EMC European Standards. The EC declaration of conformity of the electrical and electronic apparatus with the provisions of this Directive shall be marked by placing stylised CE letters on the apparatus housing. All necessary tests (as required for instance in , EN 50081-1, EN 50081-2, EN 50082-1, EN 50082-2, EN 61000-6-1, EN 61000-6-2, EN 61000-6-3, EN 61000-6-4, EN 55024, 60601-1-2, etc.) may be performed in Laboratorium Urządzeń Elektronicznych.

That's not a jet-set - that's a GTEM cell - the most modern technique of disturbance field strength measurement and electromagnetic field immunity testing.
