IMININEMBU YESIKHATI EPHAMBENI EPHAMBENI EKWIINDAWO ZE-AMERICA

1. Umehluko wokubulisa

Ngokwesintsho 20, 45, 60, okanye 90 imizuzu , ngokwesendawo seyakwiyo (umzekelo, imizuzwana yomhle izinga 20–45 min ).

Kufuneka kuba kuchwetshwe kanye neqinisekiso nguwo amagrembo akhoyo (umzekelo, UL , Intertek/WH ).

2. Ukucaciswa Kwesicathami

Iindlela ezinembane ngokwezixhobo zokutshona zinezixhobo ezinjalo isicathami esijikelezileyo , isicathami esikhanyisiweyo , noma isicathami .

Kufuneka inyame ukuba yinxalenye yekhile ephelileyo, iindlela nezixhobo apholileyo ngexesha lokutshona.

3. Imatererya

Izinto ezisetyenziswa ngokubangelwa:

Steel

Umgca ojikelezileyo onobisi obukhuseleko lwokutshona

Amaliphi okanye amaglasileyo (usebenza kakhulu)

Ama-edjyo ngamaxesha amaninzi ayongeza nge steel or iistrip yenqanawe .

4. Iindlela zokulaya ngokuzibophelelo

Ifunekileyo : Zonke iindlela ezinamvume yokulaya kufuneka zibe zilayele ngokuzibophelelo kwaye zikhuphe ngokuzibophelelo .

Iindlela zokulaya kufuneka zivavanye ngokukhangeleka nokusebenza ngokulaya (UL 10C).

5. Iisele yenqanawe / Iigasketi

Iindlela kufuneka zine iisele ezinamvume yokulaya (ngokukhulu iindlela ezinelelo "S").

Iisele yesiphambu zikhulisa ngokunyukela ukublocka ukugxa kweyonye kanye nokulamnga.

6. Iinkonzo zobuchwepheshe

Umobu oqinisekisiweyo wobuchwepheshe unemigca emikutshelene neyokubhala

Iihinges, iiclosers, kunye neelocks ezineqinisekiso lobuchwepheshe

Imithombo yokuphula okanye iindleke zo kuphuma (kudingekile kiziko elinebantle kakhulu)

Akanakubatwa jonga ukuba iqinisekisiwe kwaye inqinisekiswe njengeqinisekisiweyo

Iingcambu kunye nezinye iindlela zokugcinwa kufuneka imetali kwaye kufunele kuxhomekeke kwiilayisensi ze-UL yomkonto.

7. Iimpawu/Iiglas

Icula kwisize eifakweyo (umzekelo, 100 sq. in. max for 60- and 90-minute doors).

Kufuneka usebenyiswe iiglas ebonisa ngomkonto or i-ceramic glazing ngebhikithi ecululeko.

8. Ukusetyenziswa kwe-labels

Umntla ngamnye kufuneka ube ne umaki wokubulisa oludala (umaki owayo okanye umaki ophangwe).

Iimaki kufuneka zibonise umehluko wokubulisa , umcibiselo , kunye no igunya lokuvavanya (njengoko, “UL 45 min”).

9. Iindikileyo eziyinkimbuka

Iinkimbuka eziwayo okanye ezedolo zincediswa, nezinye iivavanyo zonke zimeyweyo.

Iifreyimu kufuneka zihlakane ngokufanelekileyo kunye ifanekane ngeyongqokoleyo yeqonga lemoti .

10. Ukufaka kwaye ukujonge

Kufuneka ufakwe ngokwesiqhelo NFPA 80 kwaye imiyalelo yomkhiqizo .

Nyaka ukujonga iqonga lemoti kudingekile (NFPA 80), ubunxibelelwano nobude beemathiklithi kunye neemathiklithi.
