SL-FL25 Heat Transfer Index Test Apparatus
Heat Transfer Index Test Apparatus for Evaluate the Thermal Protection Performance of Protective Clothing Fabrics
Product introduction of the Saħħan Trasferiment Apparat Indiċi test
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.

Prodott Feature of the Saħħan Trasferiment Apparat Indiċi test
Hija tista display temperatura fjamma, temperatura miżura u l-ħin diġitali.
L-apparat huwa ddisinjat u mmanifatturat skont EN 367 u ISO9151 istandards.
L-apparat jikkonsisti tal-berner, il-folja kopertura u d-detentur kampjun ma calorimeter ram.
Il-folja kopertura u d-detentur kampjun huma kkontrollati permezz tat-trażmissjoni pnewmatika li huwa awtomatikament kkontrollata permezz ta 'softwer.
Kampjun tat-test orjentati orizzontalment soġġetti għal fluss tas-sħana inċident ta '80KW / ㎡from-fjamma ta' berner Meker taħt dan.
Il-sħana li jgħaddi mill-kampjun huwa mkejjel permezz ta 'calorimeter ram żgħir fuq quċċata ta' u l-kuntatt mal-kampjun.
Il-ħin biex jirreġistra żieda fit-temperatura ta '12 jew 24 ℃ fil-calorimeter hija rreġistrata f'sekondi.
Il-mezz calorimeter tkessiħ jitqassar iż-żmien tat-test.
Ir-riżultat medju għat-tliet kampjuni tat-test huwa kkalkolat bħala l-HTI.
Il-kalibrazzjoni ta 'densità tal-fluss tas-sħana ta' 80 kW / ㎡is mwettqa awtomatikament mill softwa
Istrument karatteristiċi
Prodott application of the Saħħan Trasferiment Apparat Indiċi test
Il-mezz konvetiva test tar-reżistenza tas-sħana għall materjal protettiv huwa strument li huwa prinċipalment użat biex jitkejjel l-reżistenza tas-sħana konvetiva ta 'tessuti, provvisti tifi tan-nar u materjali oħra.
