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 Heat Transfer Index Test {asa
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.
