Background

Electromagnetic kuenderana (EMC) inoreva mamiriro ekushandisa emidziyo kana sisitimu inoshanda munzvimbo yemagetsi, mavasingazobudise zvisinga shivirirwe nemagetsi kukanganiswa (EMI) kune mimwe michina, kana kukanganiswa neEMI kubva kune mimwe michina.EMC ine zvinhu zviviri zvinotevera:

• Equipment kana sisitimu haizoburitse EMI inodarika muganho munzvimbo yayo yekushanda.
• Equipment kana sisitimu ine imwe anti-kupindira munzvimbo yemagetsi emagetsi, uye ine imwe margin.

Zvizhinji zvemagetsi nemagetsi zvigadzirwa zvinogadzirwa nehunyanzvi hwekukurumidza kusimudzira.Sezvo kukanganiswa kwemagetsi kuchizokanganisa mimwe michina, uye zvakare kukonzera kukanganisa kumuviri wemunhu, nyika zhinji dzakadzora mitemo inomanikidzirwa pamidziyo EMC.Pazasi pane sumo yemutemo weEMC muEU, USA, Japan, South Korea neChina yaunofanirwa kutevedzera:

Iyo EU

Zvigadzirwa zvinofanirwa kutevedzera zvinodiwa neEC paEMC uye zvakamisikidzwa ne “CE” logo kuratidza chigadzirwa chinotevedzera.PaNzira Itsva yeKuenderana Kwehunyanzvi uye Maitiro.Murairo weEMC ndeye 2014/30/EU.Uyu murairo unobata zvese zvemagetsi uye zvemagetsi zvigadzirwa.Iyo dhairekitori inovhara akawanda EMC zviyero zveEMI uye EMS.Pazasi pane akajairika anoshandiswa zviyero:

• Czvakakamurwa nebasa

• Yakakamurwa nemhoteredzo

USA

Federal Communication Commission (FCC) ndiro dhipatimendi rinotonga reEMC.FCC yakapa pamusoro pezviyero zve100 kutanga kubva kuChikamu 0. Iyi miyero yakanyorwa mu47 CFR, inova ndiyo inosungirwa kudiwa kuti upinde mumusika weAmerica.FCC inoda akasiyana certification mode zvinoenderana nemhando dzakasiyana dzezvigadzirwa.

Japani

Japan EMC chinodiwa chinobva kuMutemo weMagetsi Zvigadzirwa Chengetedzo, iri nezvePSE chitupa.

PSE inovhara 116 chaiyo zvigadzirwa zvemagetsi uye 341 zvisina kujeka zvigadzirwa zvemagetsi.Kune izvi zvigadzirwa, ivo vanofanirwa kutevedzera kwete chete mutemo wekuchengetedza, asiwo EMC inodiwa.Parizvino pane chete EMI inosanganisirwa muJapan EMC mutemo.Izvo zvinoenderana nemitemo ndeiyi pazasi:

Korea

KC ndiyo inomanikidzwa certification chirongwa muSouth Korea.Kubva July 1^st2012, KC yakaparadzanisa EMC uye chitupa chekuchengetedza, uye zvitupa zvichapihwa zvakasiyana.

Kubva July 1^st2013, Korea Communication Commission (KCC), iyo dhipatimendi inodzora EMC mitemo, shanduko kuMSIP.

Kune zvigadzirwa zvine anopfuura 9kHz oscillation zvikamu zvinofanirwa kuita EMC bvunzo, kusanganisira EMI uye EMS.

China

MuChina, kune CCC certification yemagetsi nemagetsi zvigadzirwa EMC.Parizvino pane chinodiwa chete pakukanganisa uye harmonic wave.EMS kuongorora haidiwi.

Cherechedzai

Pane misiyano yakawanda yeEMC zvinodiwa pakati penyika.Semuenzaniso, FCC, PSE neChina kutonga kunongoda EMI bvunzo, asi muEU neSouth Korea zvinoda zvese EMI neEMS, chinova chikumbiro chakasimba.Naizvozvo, usati wapinda pamusika wako waunoda, zvingave nani kuziva iyo mirau pamberi.

Kana pane chinodiwa, tinokugamuchirai kuti mutibate.
