UMTHETHO KAREESE – 16 CFR 1263

Nge-16 ka-Agasti ka-2022, uMongameli wase-US uJoe Biden watyikitya umthetho okhusela abantwana kunye nabanye abathengi kwiingozi ezinxulumene nokungeniswa ngengozi kweeseli zeqhosha okanye iibhetri zengqekembe. "Umthetho kaReese" wenziwa ukuhlonipha uReese Hamsmith, umntwana oneenyanga ezili-18 osweleke ngo-2020 emva kokungena ibhetri yeqhosha elikude.

NgoSeptemba 21, 2023IKhomishini yoKhuseleko lweMveliso yoMthengi wase-US (CPSC)upapashe umgaqo wokugqibela onamalungiselelo achaziweyoiqhosha kunye neengqekembe zeebhetri zeseliifunyenwe kwiimveliso zekhaya eziqhelekileyo.

Umgaqo wokugqibela unezaziso ezimbini zeRejista ye-Federal: enye ibandakanya inguqulelo ka-2023 yomgangatho woshishino.UL 4200Anjengomgaqo osisinyanzelo womanyano (ukwamkelwa kwe-16 CFR 1263), kunye nezinye ikwazisa ukupakishwa okungaphezulu kunye neemfuno zokuleyibheli zamaqhosha kunye neebhetri zengqekembe ezingagqunywangaUL 4200A.

Ezi mfuno azisebenzi kwiimveliso zokudlala zabantwana abangaphantsi kweminyaka eyi-14 ukuba iimveliso ziyahambelanaUmgangatho woKhuseleko lwe-ASTM F963.

Umhla osebenzayo we-16 CFR 1263, ngaphandle kokuba i-CPSC ifumana kwaye iyamkela "iinkcazo ezibalulekileyo ezingathandekiyo" ngo-Oktobha 23, 2023, kodwa iKhomishoni inika ixesha le-180 lenguqu yokunyanzeliswa kokunyanzeliswa kwe-21, i-2023, ngo-Matshi 19, i-2024.

Ukumakisha-Ukupakishwa

Ngaphandle kweemeko zemveliso ngaphandle kokupakishwa okanye ukupakisha ipaneli yokubonisa incinci kakhulu, indawo yolawulo yokubonisa iyakuqulatha ileyibhile yesilumkiso. I-ayikhoni iya kuba yi-7 mm ubuncinane ububanzi kunye ne-9 mm ubude. I-ayikhoni iya kuba yi-8 mm ubuncinane (0.31 in) ububanzi. Okubhaliweyo kwileyibhile yesilumkiso kuya kuba njengoko kubonisiwe. Xa kwileyibhile eprintiweyo kusetyenziswa ngaphezulu kombala omnye ukuphawula kufuneka kusebenzise imibala njengoko kubonisiwe.

Ukumakisha- iMveliso

Ngaphandle kweemeko xa imveliso inesithuba esincinci kakhulu, iimveliso zabathengi ziya kuphawulwa ngeleyibhile elumkisayo kwiphaneli yokubonisa imveliso eyazisa umthengi ngobukho beqhosha leqhosha okanye ibhetri yenkozo. Isicatshulwa esisisilumkiso siya kubandakanya isimboli yesilumkiso sokhuseleko, igama lomqondiso, kunye nesicatshulwa. Xa kwileyibhile eprintiweyo kusetyenziswa umbala ongaphezulu kwesinye ukuphawulwa makusebenzise umbala njengoko kubonisiwe.

IiMfuneko zoncwadi lokufundisa

Imiyalelo kunye neencwadana, ukuba zikhona, ziya kubandakanya onke amanqaku afanelekileyo kunye neenkcazo ezichazwe ngezantsi. Ukuba imiyalelo kunye neencwadana zemigaqo azibonelelwanga, iinkcazo ziya kubakho kwipaneli yokubonisa enqununu okanye kwiphaneli yesiboniso sesibini sokupakishwa kwemveliso yabathengi, okanye ukuba akukho phakheji yemveliso yomthengi, i-hang tag ehamba kunye okanye ileyibhile yesitikha.

a) Isiteyitimenti esithi “Susa kwaye ngoko nangoko usetyenziswe ngokutsha okanye ulahle iibhetri esele zisetyenzisiwe ngokwemigaqo yendawo kwaye uzigcine kude nabantwana. UNGAZIlahla iibhetri kwinkunkuma yasekhaya okanye utshise.”

b) Ingxelo ethi "Kwanebhetri esetyenzisiweyo inokubangela ukwenzakala kakhulu okanye ukufa."

c) Isiteyitimenti "Fowunela iziko lolawulo lwetyhefu lengingqi ngolwazi lonyango."

d) Ingxelo ebonisa uhlobo lwebhetri oluhambelanayo (umz., LR44, CR2032).

e) Ingxelo ebonisa amandla ombane ebhetri.

f) Isiteyitimenti “Iibhetri ezingatshajwayo akufunekanga zitshajwe kwakhona.”

g) Isiteyitimenti “Musa ukunyanzela ukukhupha, ukutshaja ngokutsha, ukuqhaqha, ubushushu obungaphezulu (umlinganiselo wobushushu obuchaziweyo umenzi) okanye utshise.Ukwenza oko kunokubangela ukwenzakala ngenxa yokuphuma komoya, ukuvuza okanye ugqabhuko-dubulo olukhokelela ekutshisweni kwemichiza.

Iimveliso ezinokutshintshwa kweqhosha / iibhetri zeeseli zengqekembe ziya kubandakanya

a) Isiteyitimenti “Qinisekisa ukuba iibhetri zifakwe ngokuchanekileyo ngokwe polarity (+ kunye -).”

b) Isiteyitimenti esithi “Musa ukudibanisa iibhetri ezindala nezintsha, iintlobo ezahlukeneyo zeebhetri, njengealkaline, i-carbon-zinc, okanye iibhetri ezinokutshajwa kwakhona.”

c) Isiteyitimenti "Susa kwaye usetyenziswe ngokukhawuleza okanye ulahle iibhetri kwisixhobo esingasetyenziswanga ixesha elide ngokwemigaqo yendawo."

d) Isiteyitimenti "Soloko uyikhusela ngokupheleleyo indawo yebhetri. Ukuba indawo yebhetri ayivaleki ngokukhuselekileyo, yeka ukusebenzisa imveliso, susa iibhetri, kwaye uzigcine kude nabantwana."

Ukusebenza

Ukukhuselwa kokuTyelwa okanye ukulangazelela iQhosha/Iibhetri zeSeli yemali

Iimveliso aziyi kubonisa umngcipheko wokufikelela ngokungeyonjongo ngabantwana kwiqhosha / iiseli zemali. Iqhosha / iibhetri zeeseli zengqekembe aziyi kufikeleleka okanye zikhululwe kwimveliso ngenxa yovavanyo lokusetyenziswa kakubi koomatshini kwimigangatho yokhuseleko esebenzayo yemveliso, kwaye iimveliso ezineqhosha / iiseli zengqekembe ziya kuhambelana novavanyo kwi-6.2 - 6.4.:

Isampuli enye yovavanyo iya kuxhomekeka kwezi meko zilandelayo zangaphambi kokulungiswa ngokulandelelana ngaphambi kovavanyo kwi-6.3 kunye ne-6.4, njengoko kusebenza:

a) Uvavanyo loNcedo loxinzelelo

- Isampulu yemveliso epheleleyo kufuneka ifakwe kwi-oven yomoya ejikelezayo ixesha le-7 h. Ubushushu be-oveni kufuneka bubekwe kwindawo ephezulu (1) okanye (2) ngezantsi. Emva kokususwa kwi-oven, isampuli ivunyelwe ukupholisa kwiqondo lokushisa.

1) 70°C (158°F); okanye

2) 10°C (18°F) ngaphezulu kobona bushushu buphezulu beendawo ezivalekileyo ze-thermoplastic, umnyango/izigqubuthelo zegumbi lebhetri, okanye ucango lwekhompatimenti yebhetri/iindlela zokugquma ngexesha lolona setyenziso lungqongqo lwesiqhelo lwesixhobo.

b) Uvavanyo loTshintsho lwebhetri

- Ucango lwegumbi lebhetri luya kuvulwa luvalwe, kwaye ibhetri isuswe kwaye ibuyiselwe, kumjikelo we-10 iyonke. Inkqubo iyakulinganisa ukutshintshwa ngokwemiyalelo yomenzi.

Uvavanyo lokuxhatshazwa

Iimvavanyo kwi-6.3.2 - 6.3.4 ziya kwenziwa ngokulandelelanayo, njengoko kusebenza, kwisampuli enye yangaphambili yemveliso. Emva kokuba yonke imiqathango yovavanyo igqityiwe, ukuthotyelwa kwemigaqo kuhlolwa ngu-6.3.5.

Uvavanyo lokuwisa

Izixhobo eziphathwayo ziphantsi kovavanyo lokuwa ukusuka kumphakamo we-1.0 m (39.4 ngaphakathi) ukuya kwindawo ethe tyaba eyenziwe ngomthi oqinileyo kwindawo enokuthi ivelise amandla aphezulu kwigumbi lebhetri okanye indawo ebiyelweyo.

Izixhobo eziphathekayo ziphantsi kwe-3 yehla, ngaphandle kweemveliso ezibanjwe ngesandla ziphantsi kwe-10 drops. Umphezulu womthi oqinileyo kufuneka ubuncinci ube yi-13 mm (1/2 in) ubukhulu, uxhonywe kumaleko amabini e-19 mm (3/4 in) yeplywood eshinyeneyo, ibekwe phezu kwekhonkrithi okanye umgangatho olingana nawo ongagungqiyo.

Uvavanyo lweMpembelelo

Indawo ebiyelweyo okanye indawo yebhetri ucango/isigqubuthelo siyakuxhomekeka kwiimpembelelo ezintathu, 2-J (1.5-ft·lbf). Le mpembelelo kufuneka iveliswe ngokuwisa i-sphere yentsimbi, i-50.8 mm (i-intshi ezi-2) ububanzi, kwaye inobunzima obumalunga ne-0.5 kg (1.1 lb) ukusuka kumphakamo ofunekayo ukuvelisa impembelelo echaziweyo okanye i-sphere yentsimbi kufuneka inqunyanyiswe ngentambo kwaye ijiwulwe njenge-pendulum, iwise umgama othe nkqo ukubetha umphezulu ofunekayo ukuze ubangele umphezulu ochaziweyo. Ingqukuva yentsimbi kukubetha ucango lwekhompatimenti yebhetri/isigqubuthelo esithe gqolo ukuya kumphezulu ovalekileyo.

Crush Test

Isampuli kufuneka ixhaswe ngumgangatho oqinileyo oqinileyo oxhasayo, kwizikhundla ezinokuthi zivelise iziphumo ezibi kakhulu ukuba nje isikhundla sinokuzixhasa. Amandla okutyumza kwe-330 ± 5 N (74.2 ±1.1 lbf) isetyenziswe kwixesha le-10 kwiindawo ezicacileyo. Amandla kufuneka asetyenziswe ngumphezulu osicaba olinganisa malunga ne-100 nge-250 mm (3.9 nge-9.8 ngaphakathi). Ukuba umntwana unokubamba nayiphi na indawo yebhetri evalelweyo kwimveliso yomthengi kuquka ucango okanye isiciko, ubuncinane ngobhontsi nomnwe, okanye usebenzisa amazinyo, sebenzisa olu vavanyo lulandelayo.

Uvavanyo lweTorque

-Faka uVavanyo lweTorque yokuSuswa kwaMacandelo nge-ASTM F963, kwindawo ebiyelweyo yebhetri, usebenzisa i-torque ye-0.50 Nm ubuncinane (4.4 in-lbf).

Uvavanyo loxinzelelo

-Faka uVavanyo lweTension lokususwa kweMicimbi kwi-ASTM F963, kwindawo ebiyelweyo yebhetri, usebenzisa amandla obuncinci be-72.0 N (16.2 lbf).

Uvavanyo lokuthobela

Emva kweemvavanyo ze-6.3.2 - 6.3.4B, amandla e-50 + 10 / -0 N (11.2 +2.2 / -0 lbf) isetyenziselwa i-10 s kwi-battery compartment umnyango / ikhava okanye i-enclosure ngomnwe wokuvavanya oqinile ngokwe-Test Probe 11 ye-IEC 610032 eyona ndawo i-pro unfavo32. indlela engafanelekanga. Amandla aya kusetyenziswa kwicala elinye kuphela. Ucango/ikhava yegumbi lebhetri ayiyi kuvuleka kwaye iya kuhlala isebenza. Ibhetri ayinakufikeleleka.
