HTI EN 367 ISO9151 Protective Clothing Against Heat and Flame Test Apparatus
Product Description
-
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 was calculated from the mean time in seconds to achieve a temperature rise of 24±0.2ºC when testing by this method using a copper disc and a starting temperature of 25±5ºC.
HTI EN 367 ISO9151 Protective Clothing Against Heat and Flame Test Apparatus is used to determine the heat transmission of flame exposure to protective clothing against heat and flames.
A classification of materials can be made by comparing the determined heat transfer indices, which serve as a reference for the relative heat transfer under the specified test conditions.

Features
- HTI EN 367 ISO9151 Protective Clothing Against Heat and Flame Test Apparatus is designed and manufactured according to EN 367 and ISO9151 standards.
- It consists of the burner, the cover sheet and the specimen holder with copper calorimeter.
- The cover sheet and the specimen holder are controlled via pneumatic transmission which is automatically controlled by software.
- A horizontally oriented test specimen was subjected to an incident heat flux of 80KW/m2 from the flame of a Meker burner beneath it.
- The heat passing through the specimen is measured by means of a small copper calorimeter on top of and in contact with the specimen.
- The time to record a temperature rise of 12 or 24ºC in the calorimeter is recorded in seconds.
- The calorimeter cooling device shortens the test time.
- The mean result for the three test specimens is calculated as the HTI.
- The calibration of the heat flow density of 80 kW/m2 is performed automatically by software.
