Waa maxay macnaha "shahaadadda CE"?
Shahaadada CE waa baasaboorka alaabada soo galaya EU iyo wadamada Aagga Ganacsiga Xorta ah ee Yurub. Si loo galo EU iyo Aagga Ganacsiga Xorta ah ee Yurub, badeecadaha waddan kasta waa inay haystaan CE-shahaado iyo CE oo ku calaamadsan badeecada. Shahaadada CE waxay muujineysaa in alaabtu ay buuxisay shuruudaha badbaadada ee uu dhigayo Awaamiirta Midowga Yurub; Alaabooyinka lagu calaamadeeyay calaamadda CE waxay yareyn doontaa halista iibka ee suuqa Yurub, gaar ahaan, shahaadada CE waa in lagu maamulaa hay'adda la ogeysiiyay ee ay fasaxday Midowga Yurub.
CE waa calaamad muujinaysa in alaabtu ay buuxisay heerarka iyo awaamiirta taxanaha Badbaadada/Caafimaadka/Deegaanka/Fayadhowrka Yurub.
Mashaariicda tijaabada nalalka LED-ka ee CE waxay leeyihiin shan dhinac oo soo socda:
1.EMC-EN55015
2.EMC-EN61547
3.LVD-EN60598
4. Haddii ay tahay LVD oo leh toosiye, guud ahaan samee EN61347
5.EN61000-3-2/-3 (tijaabada harmonics)
CE waxay ka kooban tahay EMC (waafaqsanaanta korantada) + LVD (amarka korantada hoose). EMC sidoo kale waxaa ku jira EMI (faragelin) + EMS (faragelinta-ka-hortagga), LVD guud ahaan waa badbaadada AMMAANKA, guud ahaan alaabada korantada yar AC wax ka yar 50V, DC in ka yar 75V ma samayn karto mashaariicda LVD. Alaabooyinka korantada yar waxay kaliya isticmaalaan EMC si ay u tijaabiyaan, shahaadada CE-EMC, alaabta korantada sare waxay u baahan yihiin inay tijaabiyaan EMC iyo LVD, iyo laba shahaado iyo warbixin CE-EMC CE-LVD.
EMC (waafaqsanaanta korantada) -- Heerka imtixaanka EMC (EN55015, EN61547), walxaha tijaabada ah waxaa ka mid ah dhinacyada soo socda: 1. shucaaca shucaaca 2. conduction conduction 3.ESD static 4.CS conduction anti-faragelinta 5.RS shucaaca anti-faragelinta 6. garaaca wadnaha EFT.
LVD (Dardaaranka Korantada Hoose) - Heerka Imtixaanka LVD (EN60598), walxaha tijaabada ah waxaa ka mid ah dhinacyada soo socda:
1. Khaladka (imtixaanka) 2. Saamaynta 3. Gariir 4. Naxdin
5. Nadiifinta 6. Masaafada gurguurta 7. shoog koronto
8. qandho 9. xad dhaaf ah 10. Tijaabada heerkulka heerkulka.
