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 Joto Transfer Index Mtihani 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.

Bidhaa Feature of the Joto Transfer Index Mtihani Apparatus
Inaweza kuonyesha moto joto, kipimo joto na wakati teknolojia.
Vifaa ni iliyoundwa na viwandani kwa mujibu wa EN 367 na viwango ISO9151.
Vifaa lina burner, karatasi cover na mmiliki sampuli na calorimeter shaba.
Karatasi cover na mmiliki specimen ni kudhibitiwa kupitia maambukizi nyumatiki ambayo ni moja kwa moja kudhibitiwa na kompyuta.
Sambamba oriented mtihani sampuli wanakabiliwa na tukio joto kutoka damu ya 80KW / ㎡from moto wa Meker burner chini yake.
Joto kupita kwa njia ya sampuli ni kipimo kwa njia ya calorimeter ndogo shaba juu ya na kuwasiliana na sampuli.
Muda wa rekodi kupanda kwa joto la 12 au 24 ℃ katika calorimeter imerekodiwa katika sekunde.
Calorimeter baridi kifaa kufupisha muda mtihani.
Matokeo yake wastani kwa sampuli ya mtihani tatu ni mahesabu kama HTI.
Urekebishaji vya msongamano joto mtiririko wa 80 kW / ㎡is kazi moja kwa moja na Softwa
