zvigadzirwa

EMC directive
(89/336/EEC)
Imwe yemirairo yeEU iyo FSC inotevedzera ndeye EMC
kuraira, kana Kanzuru Directive 89/336/EEC ye3 Chivabvu 1989 pa
kuenzanisa kwemitemo yeNhengo dzeNyika dzine chekuita ne
electromagnetic kuenderana sezvainodanwa zviri pamutemo. Izvo "zvinoshanda kune
midziyo inokonzeresa kukanganisa kwe electromagnetic kana iyo
kuita kwayo kunokonzeresa kukanganiswa nekukanganiswa kwakadai"
(Chinyorwa 2).
Iyo EMC dhairekitori inotsanangura kuchengetedza zvinodiwa uye kuongorora
maitiro ane chekuita nemagetsi kuenderana kweakasiyana siyana
zvemagetsi nemagetsi zvinhu.
Mukati mechirevo cheEMC rairo, 'midziyo' zvinoreva zvese
midziyo yemagetsi neyemagetsi pamwe chete nemidziyo uye
zvigadziriso zvine magetsi uye/kana zvinhu zvemagetsi.
'Electromagnetic disturbance' zvinoreva chero chinhu chinonzi electromagnetic phenomenon
iyo inogona kukanganisa kushanda kwechigadzirwa, chikwata chemidziyo kana
system. Kukanganiswa kwemagetsi kunogona kunge kuri ruzha rwemagetsi,
chiratidzo chisingadiwe kana shanduko musvikiro rekuparadzira pacharo.
'Electromagnetic kuenderana' kugona kwechigadzirwa, chikamu che
mudziyo kana sisitimu kuti ishande zvinogutsa mumagetsi ayo emagetsi
nharaunda pasina kuunza isingashiviriki emagetsi
kukanganisa kune chero chinhu chiri munharaunda iyoyo.
Kune mativi maviri kune electromagnetic kuenderana: emission uye
immunity. Izvi zviviri zvakakosha zvinodiwa zvakanyorwa muChinyorwa 4,
iyo inotaura kuti mudziyo unofanirwa kugadzirwa kuti:
(a) iyo electromagnetic disturbance yainogadzira haipfuure a
nhanho inobvumira redhiyo nenharembozha midziyo nezvimwe
midziyo kuti ishande sezvakarongwa;
(b) mudziyo une chiyero chakaringana chemukati mekudzivirira kwe
electromagnetic kukanganisa kuti iite kuti ishande sezvayakada.
Iyo EMC dhairekitori yakatanga kuburitswa mu Official Journal ye
European Communities musi waMay 23, 1989. Murairo wacho wakava
inoshanda pana January 1, 1992, nenhambo yemakore mana yokuchinja.
Munguva yekuchinja, mugadziri anogona kusarudza kusangana
mitemo yenyika iripo (yenyika yekuisirwa) kana kutevedzera
iyo EMC dhairekitori (inoratidzwa neEC yekumaka uye Declaration
of Conformity). Nguva yekushandura yakapera musi waDecember 31, 1995,
zvaireva kuti kubva muna Ndira 1, 1996 kutevedzera EMC
kuraira kwakava kusungirwa (chinodiwa chepamutemo). Zvese zvemagetsi
zvigadzirwa zvinogona kutengeswa chete muEuropean Union kana ivo
kuzadzisa zvinodiwa zvakaiswa mukuraira kweEMC. Izvi zvakare
inoshanda kune FSC system makabati.
