Product Feature and Application of the Surface Spread Flame Tester
Iinsetjenziswa 1.This siqukethe iphaneli emisebeni ukukhwezwa phezulu ozungezayo futhi asekelwe elimiswe ngohlaka lwezingodo.
2.The iphaneli emisebeni is ezingcoliswe nge ukuhamba komoya negesi.
3.The iphaneli emisebeni eyingozi kuba sezingeni 850mm square okwesikhathi ukungena nakwamanye amazwe uhlobo refractory sikaphalafini block ukunika amandla omlilo kahle ingxube emoyeni-ukuhamba komoya negesi, kungekho amalangabi okwenzeka ebusweni iphaneli ngaphansi kwezimo zokusebenza.
4.The iphaneli ngemisebe ozungezayo yayo zisekelwa elimiswe ngohlaka lwezingodo ukuze maphakathi iphaneli imayelana 1250 ± 100mm ngaphezu kogu phansi.
5.A ndlovu umnikazi kanye ilungiselelo umshayeli ilangabi ukukhwezwa komunye uhlangothi kulandzelana nekuhlunga tinsita.
6.The ndlovu umnikazi okungukuthi zimumethe amanzi selehlile Uhlaka lwensimbi ngamanzi selehlile ubuso amapuleti. Lezi zingqimba ubuso kuyinto ukugqagqana zezinhlobo by 20 ± 2mm phezu kwabo nangezansi futhi phezu konqenqema mpo eseduze iphaneli ngemisebe.
7.A entwasahlobo ukulayishwa ngocingo ibekwe ukuba ukunqanda isifanekiso ngokumelene nobuso amapuleti.
8.The alondoloze nemithombo yamanzi ephathekayo umnikazi ndlovu ukwenza lokushisa esiphezulu ingeqi 35 ℃ kwayo kuleyo ndawo yokuhweba kusuka umnikazi ndlovu.
9.The umnikazi ndlovu inhlangano sise 90 ± 2 ° ukuze ubuso iphaneli ngemisebe futhi ezifana ngendlela ubuso phezulu nabaqondisi phansi umnikazi ndlovu kukhona indiza efanayo ngaphakathi ebusweni ozungezayo iphaneli ngemisebe.
10.The ukuphakama umnikazi lowomfanekiso esinanyathiselwe ukuvumela ukuba wavuleka nendawo, kude ubuso iphaneli emisebeni phakathi ukuhlolwa, kusukela isikhundla ukuhlolwa kwindawo eceleni i-alcohol.
11.The umshayeli sikaphalafini kuyinto kuqukathe steel tube.
12.The igesi kanye air imigqa iphaneli emisebeni aqukethe ukugeleza amamitha, ingcindezi nabalawuli, ukulawula valve kanye namadivayisi ukuphepha.
13.Heat Flux Imitha: Ibanga: 0 ~ 50 kW / m2; Surface emissivity: ɛ = 0.95 ± 0.05.
14.Dummy Samandla ibhodi umnikazi, ulinganiswe ukushisa yokucucuza imitha futhi obandayo.
Umkhiqizo Imininingwane Surface Spread Flame T ester
Ebusweni ilangabi kudivayisi esiphelweni test kuyinto BS 6853 uchungechunge ngesivinini steel flame cishe yizona ezisetshenziswa kabanzi umhloli, okuyinto efanelekayo zokwakha British steel flame amazinga cishe yizona ezisetshenziswa kabanzi test ngesivinini. Izinga kuyinto BS 476-7. Indlela yokuhlola luyasetshenziswa ukuthola isandiso lateral we ebusweni isampula futhi esekelwe isivinini. Futhi ubude isandiso inquma lizinga esivuthayo. BS 476-7 lisetshenziselwa ukukala isandiso elangabini evele obala ezindongeni Uphahla lwangaphakathi.
Indlela yokuhlola ukulinganisa ezibucayi ecucuza ekhazimulayo ngu labahleli basebenta kokhela Isampula ilangabi elincane withstanding ushintsho kancane kancane ekhazimulayo ukushisa amandla. Ukushisa ekhazimulayo iphaneli izinyathelo 850mm X 850mm. Umnikazi Ukuhlolwa ndlovu amanzi selehlile futhi ifakwe perforated Samandla isitja ezishisayo ekhazimulayo ecucuza inzwa ukuze ulinganise le ezishisayo Ukubengezela ecucuza ijika. Ukuhlolwa ithuluzi inezidingo okusezingeni eliphezulu kusayithi laboratory, futhi umsebenzisi lidinga ngaphezu izinyathelo zokuphepha ngaphambi test ithuluzi kungenziwa ababebuthene.

What is bs476?
BS 476 refers to the British standard for fire tests on building materials and structures. This test standard is split into two parts: Part 6 and Part 7. Part 7 specifies the test method for measuring the lateral spread of flame along the surface of a test specimen.
