220V 50 / 60Hz Heat Transmission Index Tester Protective Suit Flame Spread Tester
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. Heat transfer index is 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.
