What must a heat protection glove be able to do?
EN 407 specifies the requirements for a heat protection glove. There are six categories in which a heat protection glove must show what it can do.
• Fire resistance: Here, the glove is exposed to a gas flame and measured as to how long the material burns or glows after the flame has been removed.
• Protection against contact heat: A glove must withstand direct contact with heat (100°C to 500°C) for at least 15 seconds. The temperature at which the inside of the glove does not heat up by more than 10°C is measured.
• Protection against convective heat: This is about slowly penetrating heat. The length of time a glove can delay the transfer of heat is measured.
• Protection against radiant heat: The time is measured for how long a glove can delay the penetration of radiant heat.
• Resistance to small splashes of molten metal: The number of molten metal droplets required to heat the glove material to a certain temperature is counted here.
• Resistance to molten metal: This measures how many grams of molten iron the test glove can withstand until it is punctured or ignites.
