Heat Transfer Index Test Apparatus
Heat Transfer Index Test Apparatus for Evaluate the Thermal Protection Performance of Protective Clothing Fabrics
Product introduction of the Inkomba Test Tinsita Heat Transfer
A new term heat transfer index (HTI) has been introduced to avoid confusion with the thermal protective index (TPI) or other terms used in previous versions of this test. HTI calculated from the mean time in seconds to achieve a temperature rise of 24±0.2℃ when testing by this method using a copper disc and a starting temperature of 25±5℃. The heat transfer index provides a method of grading materials which does not imply that the material tested will give any precise protective time under actual use conditions.
The convective heat resistance test device is developed according to EN367 and ISO9151 test standards, and meets the requirements of the convective heat resistance test standard of domestic AQ 6103-2007 welder protective gloves. The test results are thermal protection index (HTI). The principle of the test is to measure the test time required for the back temperature of the sample to rise 12 or 24 degrees by the impact of flame on the bottom of the sample. The average value of the three tests is recorded as thermal protection index (HTI), which is used to evaluate the thermal protection performance of the protective clothing fabric.

Umkhiqizo Feature of the Inkomba Test Tinsita Heat Transfer
Kungaba ukubonisa ilangabi lokushisa, isilinganiso lokushisa kanye nesikhathi ngedijithali.
I-apharathasi yakhelwe futhi akhiwe ngokuvumelana EN 367 namazinga ISO9151.
I-apharathasi siqukethe sikaphalafini, ikhava ishidi nomnikazi ndlovu ngethusi Calorimeter.
Ikhava ishidi nomnikazi isifanekiso zilawulwa nge ukudluliswa womoya okuyinto ngokuzenzakalelayo ilawulwa isofthiwe.
A ndlovu nendawo ngamakhasimende test waquliswa ecucuza sigameko nokuvutha 80KW / ㎡from nelangabi sikaphalafini Meker ngaphansi kwalo.
Ukushisa edabula ndlovu kukalwa esebenzisa Calorimeter elincane lethusi phezu nokuxhumana isifanekiso.
Isikhathi ukuqopha kuyanda lokushisa 12 noma 24 ℃ ku Calorimeter kulotshwe ngemizuzwana.
Idivayisi Calorimeter ukupholisa sifishane sikhatsi test.
Umphumela anonya ngoba zezinhlobo ezintathu test esibaliwe HTI.
I Samandla ukushisa ukugeleza kwabantu 80 kW / ㎡is kwenziwa ngokuzenzakalelayo softwa
wensimbi izici
umkhiqizo isicelo of the Inkomba Test Tinsita Heat Transfer
I convective ukushisa ukumelana kudivayisi yokuhlola izinto zokuzivikela kuyinto ithuluzi okuyinto ikakhulu asetshenziswa ukukala convective ukushisa ukumelana izindwangu, ukulwa izimpahla umlilo kanye nezinye izinto.
