2.The tawg vaj huam sib luag yog sullied nrog ib tug roj-huab cua sib tov.
3.The tawg vaj huam sib luag yog 850mm square rau ib tug ntxeem tau refractory hom burner thaiv tsim los muab npaum combustion ntawm huab cua-roj-huab cua sib tov, uas tsis muaj Flaming tshwm sim nyob rau hauv lub ntsej muag ntawm lub vaj huam sib luag nyob rau hauv kev ua hauj lwm tej yam kev mob.
4.The tawg vaj huam sib luag thiab nws surround yog txaus siab rau ib tug lub moj khaum yog li ntawd qhov chaw ntawm lub vaj huam sib luag yog hais txog 1250 ± 100 lub hli saum toj no hauv pem teb theem.
5.A tshem me me yas dhos thiab ib tug tsav nplaim kho mounted rau ib sab ntawm lub apparatus.
6.The tshem me me yas dhos yog comprise ib tug dej-txias steel ncej nrog dej-txias ntsej muag daim hlau. Lub ntsej muag daim hlau yog overlap lub nrws los ntawm 20 ± 2 hli rau lawv sab saum toj thiab hauv qab npoo thiab tshaj ntsug ntug uas nyob ib sab mus rau lub tawg vaj huam sib luag.
7.A caij nplooj ntoos hlav loaded clamp yog positioned rau clamp lub tshem me me tiv thaiv lub ntsej muag daim hlau.
8.The portable dej mov mus rau lub tshem me me yas dhos ua lub siab tshaj plaws kub tsis ntau tshaj 35 ℃ ntawm qhov hluav taws xob los ntawm cov tshem me me yas dhos.
9.The tshem me me yas dhos ua ke yog nyob rau ntawm 90 ± 2 ° mus rau lub ntsej muag ntawm lub tawg vaj huam sib luag thiab nyob rau hauv xws li txoj kev uas lub ntsej muag ntawm lub sab saum toj thiab hauv qab ntawm cov ntawm tshem me me yas dhos yog nyob rau hauv tib lub dav hlau li lub hauv lub ntsej muag ntawm lub koos mus rau lub tawg vaj huam sib luag.
10.The qhov siab ntawm lub tshem me me yas dhos yog hinged tso cai rau nws yuav tsum tau swung horizontally, deb ntawm lub ntsej muag ntawm lub tawg vaj huam sib luag ntawm kev ntsuam xyuas, los ntawm cov xeem txoj hauj lwm mus rau lub standby txoj hauj lwm thiab vice-versa.
11.The tsav burner yog muaj xws li ib tug steel raj.
12.The roj thiab cua txaus kab mus rau lub tawg vaj huam sib luag muaj txaus meters, siab regulators, tswj li qub thiab kev nyab xeeb pab kiag li lawm.
13.Heat Flux ntsuas: Ntau: 0 ~ 50 kw / m2; Deg emissivity: ɛ = 0,95 ± 0.05.
14.Dummy calibration board nrog yas dhos, kom tshav kub flux 'meter' thiab mounting.
Khoom Paub meej ntawm lub Deg Kis Nplaim T ester
Lub nto nplaim taws tawm xeem ntaus ntawv yog ib tug BS 6853 series high-ceev steel nplaim retardant tester, uas yog haum rau British tsev cov ntaub ntawv thiab high-ceev steel nplaim retardant xeem qauv. Tus txheem yog BS 476-7. Lub xeem txoj kev yog siv los txiav txim seb lub sab extension ntawm tus qauv nto thiab raws li nyob rau hauv cov kev ceev. Thiab qhov yuav ncua ntxiv ntev txiav txim seb tus burning theem. BS 476-7 yog feem ntau siv los ntsuas cov nplaim taws extension ntawm raug chaw rau ntawm phab ntsa thiab ceilings.
Qhov kev kuaj ntawd txoj kev yog mus ntsuas qhov tseem ceeb heev radiant flux los ntawm igniting tus qauv nrog ib tug me me nplaim taws los ntawm tiv lub tsheb txhob sibtsoo kev hloov ntawm radiant tshav kub zog. Lub tshav kub radiant vaj huam sib luag kev ntsuas 850mm X 850mm. Qhov kev kuaj ntawd tshem me me yas dhos yog dej txias thiab nruab nrog ib tug perforated calibration phaj thiab ib thermal radiant flux sensor rau calibrate lub thermal radiance flux nkhaus. Qhov kev kuaj ntawd ntsuas muaj high yuav tsum rau txoj kev kuaj qhov chaw, thiab cov neeg siv yuav tsum tau ntau muaj kev ruaj ntseg ntsuas ua ntej lub xeem ntsuas yuav tsum tau koom ua ke.

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.
