EMC cov lus qhia
(89/336/EEC)
Ib qho ntawm EU cov lus qhia uas FSC ua raws yog EMC
Cov lus qhia, lossis Council Directive 89/336/EEC ntawm 3 Tsib Hlis 1989 ntawm
approximation ntawm cov kev cai lij choj ntawm lub xeev cov tswv cuab hais txog
electromagnetic compatibility raws li nws yog officially hu ua. Nws " siv rau
apparatus lav ua rau electromagnetic cuam tshuam los yog lub
kev ua haujlwm uas yuav tsum raug cuam tshuam los ntawm kev cuam tshuam zoo li no "
(Kab ntawv 2).
Txoj cai EMC qhia txog kev tiv thaiv thiab kev tshuaj xyuas
cov txheej txheem hais txog electromagnetic compatibility rau ntau yam
ntawm cov khoom siv hluav taws xob thiab hluav taws xob.
Nyob rau hauv cov ntsiab lus ntawm EMC cov lus qhia, 'apparatus' txhais tau tias tag nrho
cov khoom siv hluav taws xob thiab hluav taws xob ua ke nrog cov khoom siv thiab
kev teeb tsa uas muaj cov khoom siv hluav taws xob thiab / lossis hluav taws xob.
'Electromagnetic cuam tshuam' txhais tau tias txhua yam tshwm sim electromagnetic
uas tej zaum yuav degrade qhov kev ua tau zoo ntawm ib tug ntaus ntawv, chav tsev ntawm cov khoom los yog
qhov system. Ib qho kev cuam tshuam ntawm electromagnetic tej zaum yuav yog lub suab nrov electromagnetic,
ib qho tsis xav tau teeb liab lossis hloov pauv hauv qhov nruab nrab ntawm kev nthuav tawm nws tus kheej.
'Electromagnetic compatibility' yog lub peev xwm ntawm lub cuab yeej, chav tsev ntawm
cov khoom siv los yog qhov system ua haujlwm txaus siab hauv nws cov electromagnetic
ib puag ncig yam tsis qhia qhov tsis haum rau electromagnetic
cuam tshuam rau txhua yam hauv ib puag ncig ntawd.
Muaj ob sab rau electromagnetic compatibility: emission thiab
tiv thaiv kab mob. Ob qhov kev xav tau tseem ceeb no tau teev tseg hauv Tshooj 4,
uas hais tias ib qho cuab yeej yuav tsum tsim kom muaj:
(a) electromagnetic cuam tshuam nws generates tsis tshaj a
qib tso cai rau cov khoom siv xov tooj cua thiab kev sib txuas lus thiab lwm yam
cov cuab yeej ua haujlwm raws li qhov xav tau;
(b) cov cuab yeej muaj qib txaus ntawm kev tiv thaiv hauv nruab nrab ntawm
electromagnetic cuam tshuam kom nws ua haujlwm raws li qhov xav tau.
EMC cov lus qhia yog thawj zaug luam tawm hauv Phau Tsom Faj ntawm
Cov Neeg European nyob rau lub Tsib Hlis 23, 1989. Cov lus qhia tau los ua
siv tau rau lub Ib Hlis 1, 1992, nrog rau lub sijhawm hloov pauv plaub xyoos.
Thaum lub sijhawm hloov pauv, cov chaw tsim khoom tuaj yeem xaiv kom tau raws li
cov kev cai lij choj hauv tebchaws uas twb muaj lawm (ntawm lub tebchaws ntawm kev teeb tsa) lossis ua raws
EMC cov lus qhia (ua qauv qhia los ntawm CE cim thiab tshaj tawm
ntawm Conformity). Lub sijhawm hloov pauv tau xaus rau lub Kaum Ob Hlis 31, 1995,
uas txhais tau hais tias txij Lub Ib Hlis 1, 1996 ua raws li EMC
cov lus qhia tau los ua qhov yuav tsum tau ua (ib txoj cai lij choj). Txhua yam khoom siv hluav taws xob
cov khoom tam sim no tsuas yog muag hauv European Union yog tias lawv
Ua tau raws li cov kev xav tau hauv EMC cov lus qhia. Qhov no kuj
siv rau FSC system txee.
