How to Choose Heat Resistant Gloves

heat resistant gloves

Heat resistant gloves are essential for workers who are exposed to heat hazards. It is important to properly understand the type of gloves you need for your workplace. There are many different types of heat hazards, and you can use the legislation EN 407 to help you right heat proof gloves for you.

Heat resistant gloves are rated according to EN 407. EN 407 ratings have 6 numbers, and each shows the glove’s resistant to a certain type of hazard. Understanding these numbers is the best way to find the heat protective gloves that are right for this workplace.


EN 407 Ratings

The first number in an EN 407 rating shows the resistance to flammability. This is tested by stretching the glove material, and placing it above a flame for 15 seconds. The time that the glove then spends glowing or burning is measured, and this is used to determine the flame resistance of the glove. This number will be between 1 and 4, with higher numbers being more resistant. In environments where workers may be exposed to naked flames, gloves with a high resistance to flammability rating are important.

The second number shows resistance to contact heat. For this test, the glove’s material is exposed to temperatures between 100°C and 500°C. The amount of time it takes for the temperature to increase by 10°C is measured. To pass, this must take at least 15 seconds. The glove’s resistance to contact heat rating is based upon the highest temperature at which it can still pass the test. The rating will be between 1 and 5, with higher numbers indicating higher levels of contact heat resistance.

The next number in the EN 407 rating indicates resistance to convective heat. This is tested by exposing the glove’s material to the heat from a gas flame. The amount of time it takes to raise the temperature inside the glove by 24°C is measured. The longer this takes, the higher the glove’s resistance to convective heat. The number for this rating will be between 1 and 4.

The fourth number in the EN 407 rating shows you the glove’s resistance to radiant heat. This is tested by measuring how long the glove is able to delay the transfer of heat from a radiant heat source. Gloves with a higher rating in this category are more resistant to radiant heat, so offer better protection.

The fifth number shows the glove’s resistance to small splashes of molten metal. This tested by dropping small amounts of molten metal onto the glove. The test measures how many drops are required to raise the temperature inside by 40°C. The rating is between 1 and 4, with higher numbers being more protective.

The final number indicates the glove’s resistance to large splashes of molten metal. The test measures how much molten metal is required to damage material inside the glove. Gloves with a higher rating provide more protection against molten metal.

How to Choose the Best Heat Protection Gloves

To determine the best thermal gloves, you will need to carry out a comprehensive risk assessment of the heat hazards in your workplace. Once you know the type of hazards workers face, you can determine the kind of gloves they need. Here is a quick guide to EN 407 ratings:

EN 407 NumberRating RangeProtection Type
1 1-4 Flammability
2 1-5 Contact Heat
3 1-4 Convective Heat
4 1-4 Radiant Heat
5 1-4 Molten Metal (small splashes)
6 1-4 Molten Metal (large splashes)

Using these ratings, you can ensure your gloves will properly protect your workers. You can browse our side range heat protection gloves to find the right gloves for your workplace.
