ISO 12477Welder gloves convective heat resistance testerCompliant with standards:ISO 12447、 AQ6103

ISO 12477Purpose: To evaluate the protective properties of welding gloves and related protective clothing when exposed to flames.

ISO 12477Principle:

Fix the horizontally placed sample section, and the gas burner flame below the sample generates an incident heat flux of 80kw/m2. Measure the heat passing through the sample using a small copper calorimeter placed on top of and in contact with the sample.

Record the time of temperature rise (12 or 24 ± 0.2) ℃ in the calorimeter using S. The average value of three samples is taken as the "heat transfer index (flame)".
