Umkhiqizo Imininingwane the UL94 Flame Chamber
sikaphalafini I UL94 ovundlile mpo usebenzisa ngokugcwele ejwayelekile ukwaneliseka design mqondo futhi uyazicabangela amazinga amaningi ukuhlolwa futhi luhlanganiswe nato uvivinyo ibhokisi. I ovundlile sikaphalafini mpo yakhelwe ukuhlola UL ejwayelekile flammability ukusebenza imishini futhi lisebenze izingxenye izinto. Izinkomba Test ukusetshenziswa ekupheleni ezifana flammability, isilinganiso evutha, ilangabi ukusabalala, amandla evutha nelangabi retardancy komkhiqizo angahlolwa.
It isilandela zonke emihlanu UL 94 evundla mpo sikaphalafini ukuvivinywa ASTM ezihlobene namazinga omhlaba. Kukhona:
