Txoj kev piav qhia: Hauv chav kuaj combustion chamber, cov khoom siv hauv pem teb horizontally ignited siv lub T-zoo li tus burner. Lub tshav kub hluav taws xob hluav taws xob yog tsau ntawm lub kaum sab xis saum toj ntawm cov khoom siv thiab txuas ntxiv ua rau ntawm tus qauv saum npoo. Cov nplaim hluav taws muaj peev xwm nthuav tawm ntawm cov qauv yog pom thaum lub sijhawm kuaj. Qhov deb ntawm qhov kev nthuav dav, qhov qis dua qhov tseem ceeb ntawm cov hluav taws xob hluav taws xob hluav taws xob tsawg, thiab qhov ua tau zoo ntawm cov nplaim hluav taws xob ntawm cov qauv. Qee qhov kev ntsuam xyuas kuj tseem yuav xav tau kev sim ntxiv thiab sau cov pa luam yeeb hauv lub flue.
Kev Ua Tau Zoo: Xa mus rau cov kev xav tau hauv lub tebchaws cov cai lossis cov qauv kev lag luam.

02. Txoj kev tshuaj ntsiav
Tus Neeg Sawv Cev Txheej Txheem: GB / T 11049, ISO 6925, ASTM D2859, BS 6307, 16 CFR 1630, 16 CFR 1631
Cov qauv siv tau: Muaj feem xyuam rau txhua hom ntaub hauv pem teb, tsis hais lawv cov kev tsim kho lossis fiber ntau. (GB/T 11049, ISO 6925, BS 6307)
16 CFR 1630: Cov ntaub pua plag nrog qhov ntev ntau dua 1.83m (6ft) thiab thaj tsam ntau dua 2.23m² (24 sq.ft) (ntxuav tau xaiv raws li qhov tseeb).
16 CFR 1631: Cov ntaub pua plag nrog qhov ntev tsawg dua 1.83m (6ft) thiab thaj tsam ntau dua 2.23m² (24 sq.ft) (ntxuav tau xaiv raws li qhov tseeb).
Txoj kev piav qhia: Ib qho 230 ± 3mm square qauv yog muab tso rau kab rov tav nrog rau sab sab uas tig mus rau sab saud. Muab ib ntsiav tshuaj me me rau hauv nruab nrab ntawm cov qauv thiab maj mam ignite nws nrog ib tug igniter. Qhov kev sim no raug tso tseg thaum cov nplaim hluav taws kub hnyiab, lossis cov nplaim hluav taws kub hnyiab, kub hnyiab mus txog thaum nws tua, lossis thaum nws kub hnyiab nrog lossis tsis muaj nplaim taws mus rau ib qho ntug ntawm lub qhov ntawm lub phaj hlau. Saib xyuas qhov ntev tshaj plaws puas lawm (mm) ntawm txhua tus qauv. Rov ua qhov kev ntsuam xyuas tsawg kawg 8 tus qauv.
Cov kev cai xeem: Tsis tau teev tseg hauv GB / T 11049 / ISO 6925.
ASTM D2859 / 16 CFR 1630: Qhov kev ncua deb ntawm ntug ntawm qhov chaw hlawv thiab sab hauv ntawm lub voj voog hlau yuav tsum tsis pub tsawg tshaj 25 ± 0.5 hli (1 nti).
Test daim duab:
03 Kub Metal Nut Test (BS 4790)
Cov qauv siv tau: Muaj feem xyuam rau tag nrho cov ntaub pua tsev ntaub
Txoj kev piav qhia: Muab cov txiv ntoo rhuab mus rau 900℃± 20℃ntawm kab rov tav nteg - tawm qauv rau 30 ± 2 vib nas this. Sau seb tus qauv ignites, los yog kub kub tom qab ignition. Rov ua qhov kev ntsuam xyuas ntawm 3 cov qauv.
Kev Xeem Xeem: Xa mus rau BS 5287, uas tuaj yeem muab faib ua:

04. Cawv-Based Cotton Fabric Ignition Test (DIN 51960)
Cov qauv siv tau: Cov khoom siv hauv av organic (Ceeb toom: tsis suav nrog cov ntaub)
Txoj kev piav qhia: Tso cov qauv kab rov tav rau ntawm lub rooj ntoo, thiab tso ib daim ntawv nyias nyias (fiber daim ntaub) nrog txoj kab uas hla ntawm 25 mm nyob rau hauv nruab nrab ntawm cov qauv. Ncuav 2.5 ml ntawm 96% ntshiab ethanol sib npaug rau ntawm daim ntawv thiab taws nws. Tom qab cov nplaim hluav taws kub hnyiab, saib thiab ntsuas qhov kub siab tshaj plaws. Nco ntsoov tias tus qauv discoloration tsis suav nrog. Rov ua qhov kev ntsuam xyuas ntawm 5 tus qauv.
Kev ntsuas qhov tshwm sim:

Chav Kawm 2 --- Cov cim hlawv ntawm ib lossis ntau qhov qauv ntau tshaj 50 hli.
Cov ntsiab lus
Txoj Kev 1 muaj feem xyuam rau qhov dav tshaj plaws ntawm cov khoom lag luam thiab cov teb, muaj qee qhov kev siv dav dav, thiab yuav tsum muaj cov khoom siv hauv pem teb kom muaj cov nplaim hluav taws muaj zog- cov khoom tiv thaiv.
Txoj kev 2, 3, thiab 4 yog qhov zoo sib xws, sib txawv tsuas yog nyob rau hauv hom combustion siv. Txawm li cas los xij, Txoj Kev 2 thiab 3 yog rau cov ntaub ntawv flammable fabric flooring, xav tau cov qauv kom muaj qee yam nplaim taws-cov khoom tsis zoo; Txoj Kev 4 yog rau cov ntaub ntawv tsis yog -woven organic flooring; Txoj Kev 3 thiab 4 yog qhov tsis meej thiab tsis muaj tseeb, tsuas yog xav tau rau cov khoom muag hauv UK thiab German kev lag luam.
