▍Iyini I-CTIA CERTIFICATION?

I-CTIA, isifinyezo se-Cellular Telecommunications and Internet Association, yinhlangano yomphakathi engenzi nzuzo eyasungulwa ngo-1984 ngenjongo yokuqinisekisa ukuhlomula kwabaqhubi, abakhiqizi nabasebenzisi. I-CTIA iqukethe bonke opharetha base-US nabakhiqizi abavela kumasevisi omsakazo weselula, kanye namasevisi edatha angenantambo nemikhiqizo. Isekelwe yi-FCC (Federal Communications Commission) kanye neCongress, i-CTIA yenza ingxenye enkulu yemisebenzi nemisebenzi eyayisetshenziselwa ukwenziwa uhulumeni. Ngo-1991, i-CTIA yakha uhlelo lokuhlola lomkhiqizo olungachemile, oluzimele nolwendawo eyodwa kanye nesitifiketi somkhakha ongenazintambo. Ngaphansi kwesistimu, yonke imikhiqizo engenantambo esebangeni labathengi izothatha izivivinyo zokuthobela imithetho futhi leyo ethobelana namazinga afanele izovunyelwa ukusebenzisa ukumaka kwe-CTIA nokushayisana kwamashalofu ezitolo emakethe yezokuxhumana yaseNyakatho Melika.

I-CATL (CTIA Authorized Testing Laboratory) imele amalebhu agunyazwe yi-CTIA ukuze ahlolwe futhi abuyekezwe. Imibiko yokuhlola ekhishwe ku-CATL izogunyazwa yonke yi-CTIA. Nakuba eminye imibiko yokuhlola kanye nemiphumela evela ku-non-CATL ngeke ibonwe noma ingakwazi ukufinyelela ku-CTIA. I-CATL egunyazwe yi-CTIA iyahlukahluka ezimbonini nasekutholeni izitifiketi. I-CATL kuphela efanelekela ukuhlolwa nokuhlolwa kokuthobela ibhethri ekwazi ukufinyelela esitifiketini sebhethri ukuze ihambisane ne-IEEE1725.

▍CTIA Amazinga Wokuhlola Ibhethri

a) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobela IEEE1725— Kusebenza Ezinhlelweni Zebhethri ezineseli elilodwa noma amaseli amaningi axhunywe ngokuhambisana;

b) Isidingo Sokuthola Isitifiketi Sohlelo Lwebhethri Ukuthobelana ne-IEEE1625— Kusebenza Ezinhlelweni Zebhethri ezinamaseli amaningi axhunywe ngokuhambisana noma kokubili ngokuhambisana nochungechunge;

Amathiphu afudumele: Khetha ngenhla kwamazinga wesitifiketi ngokufanelekile kumabhethri asetshenziswa omakhalekhukhwini namakhompyutha. Ungasebenzisi kabi i-IEE1725 kumabhethri kumakhalekhukhwini noma i-IEEE1625 kumabhethri akukhompyutha.

▍Kungani i-MCM?

●Ubuchwepheshe obuqinile:Kusukela ngo-2014, i-MCM ibihambela inkomfa yamaphakethe webhethri ebanjwa yi-CTIA e-US minyaka yonke, futhi iyakwazi ukuthola isibuyekezo sakamuva futhi iqonde amathrendi enqubomgomo emisha mayelana ne-CTIA ngendlela esheshayo, enembayo nesebenzayo.

●Ukufaneleka:I-MCM iyi-CATL egunyazwe yi-CTIA futhi ifaneleka ukwenza zonke izinqubo ezihlobene nesitifiketi okuhlanganisa ukuhlola, ukuhlola kwasefekthri nokulayisha umbiko.

Ngomhla zingama-27 kuLwezi, 2023, “i-UN Manual of Tests and Criteria” (IsAm. 8) yakhululwa ngokusemthethweni kuwebhusayithi yase-United States. “Imanuwali Yezivivinyo Nemibandela Ye-UN” (IsAm. 8) yamukela ukubuyekezwa okwenziwe iseshini ye-11 ye-United Nations TDG kanye neKomidi Lochwepheshe le-GHS “kuMqulu We-UN Wokuhlola Nemibandela” (IsAm. 7) kanye Nokuchitshiyelwa kwayo 1 . Njengovivinyo oluyisisekelo lokuhamba kokuphepha kwebhethri, "I-UN Manual of Tests and Criteria" (IsAm. 8) yengeze isigaba esisha se-UN 38.3.3.2 "Ukuhlolwa kwamaseli e-sodium ion namabhethri", futhi ngesikhathi esifanayo wengeza okufakiwe okukhethekile okuhlobene namabhethri e-sodium-ion ku-UN "Izincomo Zokuthutha Kwempahla Eyingozi" (TDG) Rev. 23: UN 3551 kanye ne-UN 3522.
T.1: Ukulingisa kwe-Altitude (iseli nebhethri)
Amaseli okuhlola namabhethri azogcinwa ekucindezelweni okungu-11.6 kPa noma ngaphansi okungenani amahora ayisithupha ezingeni lokushisa elizungezile (20±5℃)
Amaseli okuhlola namabhethri kufanele agcinwe okungenani amahora ayisithupha ezingeni lokushisa lokuhlola elilingana no-72℃no -40℃. Le nqubo kufanele iphindwe kuze kube yilapho imijikelezo eyi-10 iphelele.
Amaseli namabhethri avikelwe ngokuqinile endaweni yomshini wokudlidliza, nokudlidliza kube i-waveform ye-sinusoidal ene-logarithmic sweep phakathi kuka-7 Hz no-200 Hz, kanye ne-amplitude engu-0.8mm, yeseli nebhethri elincane ukupakisha ukusheshisa okuphezulu 8 gn, kanye nephakethe lebhethri elikhulu ukusheshisa okuphezulu okungu-2 gn.
