What Tests are Carried out on EN 407 Heat Resistant Gloves?
EN 407 is a European standard specifically regulating the flame-retardant and heat-insulating properties of protective gloves. This standard applies to gloves used in environments involving high temperatures, flames, or thermal radiation, ensuring they effectively protect users from thermal injury.
Scope of Application for Flame-Retardant and Heat-Insulating Gloves EN 407
Applicable to protective gloves and other hand protection equipment, including arm protection, intended for use by professionals and non-professionals. These provide protection against one or more forms of thermal injury, including flame, contact heat, convective heat, radiant heat, minor splashes of molten metal, or significant splashes of molten metal. Excludes gloves for firefighting and welding operations.
What tests are carried out on EN 407 heat resistant gloves?
Limited flame spread The first test a work glove should be subjected to is flammability resistance. Exposed to fire and in contact with an open flame for at least 15 seconds, how long will it take the glove to stop burning? It is this time period that will determine the performance level of the protective glove, on a scale of 0 to 4; below 3, the glove’s performance is not sufficient to claim high levels of protection for the other tests.
GT-C35B Vertical Combustibility Tester This combustibility tester to determine the flammability resistance of vertically oriented fabrics and soft fabric toys.
1. Contact heat resistance test En contact avec When in contact with a heat source between 100 and 500°C, at what temperature does the glove’s internal temperature increase by 10°C during the first 15 seconds? A glove with a level 2 rating guarantees perfect resistance to contact heat up to 250°C.
GT-C101 Heat Contact Machine This test instrument applies to testing welders gloves resistance contact heat performance (for hand & wrist protection) in welding and related works process.
2. Convective Heat Resistance Test This convective heat resistance test measures the time (in seconds) that heat is transferred from a flame to the inside of the glove. The longer the protective glove is able to delay the transfer of heat from the outside to the inside of the glove, the higher its resistance level. The highest level is level 4.
Put sample on the a certain amount of heat flux fire source, test the time of temperature increasing specified value (△t=24℃) by calorimeter sample’s back. And refer it as index of judging heat conduction property.
3. Radiant Heat Resistance Test This is the exposure to heat by emission of heat rays. This test will measure the time required for the test sample to increase in temperature by 24°C inside the glove. This resistance is measured in levels from 1 to 4, the latter being the highest level for a radiant heat insulating glove.
GT-C96 Heat Radiation (Thermal Protection) Tester This device is use for heat protection test for fabric of single layer or multi-layer under the high temperature. It also can be used to determine the heat-insulating property of other fire retardant board.
Thermal radiation is a important performance indicator of flame retardant products. Accurate determination of its protective properties is very important to select materials, research and development of new products, improved processing techniques.
4. Metal Splash Test For this resistance test, a distinction is made between small and large molten metal splashes. For small splashes, we measure the amount of molten metal beads needed to raise the temperature of the glove by 40°C. The glove reaches its maximum performance level when more than 35 drops are required to raise its internal temperature. For resistance to large splashes of molten metal, the test consists of measuring the amount of molten metal required to damage the artificial skin inside the glove. The maximum level of performance is reached at 200g of molten metal.
It is used to determine the impact performance of high-temperature metal melt droplets in protective clothing and the high-temperature protection performance of textiles.
Note: It is not necessary to conduct all test items to meet CE certification requirements. Depending on the intended use and nature of the work, gloves need only undergo the corresponding tests.
