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.
