Kodi UL940 V0 ya Mzere wa LED ndi chiyani?

Underwriters Laboratories (UL) adapanga UL940 V0 flammability muyezo kuti atsimikizire kuti chinthu-muchitsanzo ichi, chingwe chowunikira cha LED-chimakwaniritsa miyezo yachitetezo chamoto ndi kuyaka. Mzere wa LED womwe uli ndi certification UL940 V0 wayesedwa kwambiri kuti uwonetsetse kuti sugwira moto ndipo sungathe kufalitsa malawi. Ndi chiphaso ichi, zingwe zowunikira za LED zimatsimikiziridwa kuti zizitsatira malamulo okhwima a chitetezo chamoto ndipo zimagwiritsidwa ntchito pamene chitetezo cha moto chimakhala chofunika kwambiri.
Zingwe za nyali ziyenera kukwaniritsa zofunikira pakuyaka komanso kukana moto zomwe zimakhazikitsidwa ndi Underwriters Laboratories (UL) kuti zitsimikizidwe kuti ndi UL94 V0. Kuthekera kwa zinthuzo kupirira kuyatsa ndikuyimitsa kufalikira kwa malawi ndiye cholinga chachikulu chazofunikira izi. Zofunikira pakupanga nyali ndi izi:
Kuzimitsa: Pamene gwero loyatsira lichotsedwa, zinthuzo ziyenera kuzimitsa zokha mu nthawi yokonzedweratu.
Kufalikira pang'ono kwa lawi: Zinthuzi zisamatenthe kwambiri kuposa momwe zimakhalira kapena kufalikira mwachangu kuposa momwe ziyenera kukhalira.
Madontho ochepa: Mankhwalawa asamatulutse madontho oyaka kapena tinthu ting'onoting'ono tomwe titha kuyatsa moto mwachangu.
Zofunikira pakuyesa: Molingana ndi muyezo wa UL94, chingwe cha nyali chiyenera kudutsa mayeso okhwima omwe amaphatikizapo kuyesa kowotcha kowongoka komanso kopingasa.
Mzere wa nyali ukakwaniritsa zofunikirazi, umasonyeza kuti uli ndi mphamvu yotsutsa kuyaka ndi kufalikira kochepa kwa moto, zomwe zimapangitsa kuti zikhale zotetezeka kuti zigwiritsidwe ntchito zosiyanasiyana-makamaka zomwe chitetezo cha moto chimakhala chofunikira.

Palibe zinthu zomwe zinganene kuti sizingayaka moto, ngakhale nyali yowunikira yomwe yapeza UL94 V0 yoyaka moto ikuwonetsa kukana kwambiri kuyaka ndi kufalikira kwamoto. Kuopsa kwa moto, zinthu zimatha kugwirabe moto pazovuta kwambiri monga kukhudzana ndi kutentha kwakukulu kwa nthawi yayitali kapena malawi achindunji. Chifukwa chake, mosasamala kanthu za kuchuluka kwa zinthu zomwe zimalimbana ndi moto, ndikofunikira kukhala osamala ndikumvera malamulo otetezeka ogwiritsira ntchito. Pomaliza, kutsimikizira kugwiritsa ntchito kotetezeka komanso koyenera kwa nyali zamagetsi kapena zinthu zina zamagetsi, ndikofunikira kumvera upangiri wa wopanga komanso wamba. malamulo oteteza moto.
