What is EN 407? Thermal Glove Protection | LESH

1 Flame Resistance

The sample glove is stretched before a flame is applied to the glove for 15 seconds. After 15 seconds the flame is removed and the time is measure until the material glows or burns.

2 Contact Heat Resistance

The exterior of the sample glove is exposed to heat between 100˚C and 500 ˚C. The temperature inside the glove is them monitored, the time is logged for the temperature inside the glove to increase by 10 ˚C. The minimum is applying 250 ˚C for 15 seconds after which time the temperature inside the glove should not exceed 35 ˚C.

3 Convective Heat Resistance

The sample glove is positioned in front of a gas flame (80Kw), the time is logged until the gloves interior reaches 24 ˚C

4 Radiant Heat Resistance

The sample glove is stretched in front of a heat source with of approx. 20-40Kw. The average time is measures for heat to penetrate of 2.5Kw

5 Small Splash of Molten Metal Resistance

The amount of small drops required is recorded to achieve a 40˚C increase in temperature inside the glove.

6 Large Splash of Molten Metal Resistance

A artificial layer of skin is positioned beneath the sample material before molten metal is poured over it. The amount in grams is measure until the artificial skin becomes damaged.
