Abstract: For current assessment of thermal protection performance for thermal protective clothing, the TPP experiment at the fabric level and the burning dummy experiment at the garment level are common. In order to explore the correlation between these two methods in thermal protection performance evaluation, this paper used both TPP tester and combustion dummy test system. The thermal protection performances of fabric layer and garment layer were studied for electrostatic clothing and fire protection clothing. The results showed: the thickness of the air layer under the clothing played an important role in the thermal protection of the fabric. And with the increase of the thickness of the air layer, the thermal protection performance of electrostatic clothing and fire clothing fabrics gradually approached each other. The amount of heat shrinkage of the garment had a significant effect on the burn location of the skin, it has little effect on the percentage of burn area. There was a certain correlation between the TPP test of fabrics and the burning dummy test of garment in evaluating the thermal protection performance of electrostatic clothing and fire protection clothing. However, there are certain differences in evaluating the strength of thermal protection performance. The thermal protection performance of the garment level cannot be completely replaced by that of the fabric level.

Key words: TPP experiment, burning dummy experiment, electrostatic clothing, fire protection clothing, thermal protection.
