Heat Transfer Index Test Apparatus
Heat Transfer Index Test Apparatus for Evaluate the Thermal Protection Performance of Protective Clothing Fabrics
Product introduction of the Thaum tshav kub kub hloov Index Test Apparatus
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.

Khoom Feature of the Thaum tshav kub kub hloov Index Test Apparatus
Nws yuav tso saib nplaim taws kub, kev ntsuas kub thiab lub sij hawm digitally.
Lub apparatus yog tsim thiab manufactured raws li EN 367 thiab ISO9151 qauv.
Lub apparatus muaj cov burner, lub hau daim ntawv thiab lub tshem me me yas dhos nrog tooj liab calorimeter.
Lub cover daim ntawv thiab lub tshem me me yas dhos yog tswj ntawm pneumatic kis tau tus mob uas yog tau tshuaj los ntawm software.
Ib tug horizontally taw qhia kom paub xeem tshem me me raug rau ib qho xwm txheej kub flux ntawm 80KW / ㎡from cov nplaim taws ntawm ib tug Meker burner hauv qab nws.
Lub tshav kub dhau los ntawm lub tshem me me yog ntsuas los ntawm txoj kev ntawm ib tug me me tooj liab calorimeter rau sab saum toj ntawm thiab kev sib cuag nrog lub tshem me me.
Lub sij hawm mus sau ib kub sawv ntawm 12 los yog 24 ℃ nyob rau hauv lub calorimeter yog kaw nyob rau hauv vib nas this.
Lub calorimeter txias ntaus ntawv kom lub xeem lub sij hawm.
Qhov mean tshwm sim rau peb xeem nrws yog xam raws li lub HTI.
Lub calibration ntawm tshav kub khiav ceev ntawm 80 kW / ㎡is ua tau los ntawm softwa
