This standard refers specifically to the thermal performance of work gloves against thermal hazards such as heat, fire and molten metal, amongst others. The glove is graded using 6 different tests, which are graded from performance level 0-4. The results of these tests are displayed below the pictogram, an ‘X’ is used when the glove hasn’t met the minimum level. Tests and levels for each are as follows:
Standard EN407
Gloves Providing Protection from Thermal Hazards
- a. Resistance to flammability - Based on the length of time the material continues to burn and glow after the source of ignition is removed (performance level 0-4)
| After Burn Time (Sec) | After Glow Time (Sec) | Level |
|---|---|---|
| < 2 | < 5 | 4 |
| < 3 | < 25 | 3 |
| < 10 | < 120 | 2 |
| < 20 | Infinity | 1 |
- b. Contact heat resistance - Based on the temperature range (100-500℃) at which the user will feel no pain for at least 15 seconds (performance level 0-4)
| Temp After 15s (℃) | Level |
|---|---|
| 500 | 4 |
| 350 | 3 |
| 250 | 2 |
| 100 | 1 |
- c. Convective heat resistance - Based on the length of time the glove is able to delay the transfer of heat from a flame (performance level 0-4)
| Seconds | Level |
|---|---|
| < 18 | 4 |
| < 10 | 3 |
| < 7 | 2 |
| < 4 | 1 |
- d. Radiant heat resistance - Based on the length of time the glove is able to delay the transfer of heat when exposed to a radiant heat source (performance level 0-4)
| Seconds | Level |
|---|---|
| < 150 | 4 |
| < 90 | 3 |
| < 30 | 2 |
| < 5 | 1 |
- e. Resistance to small splashes of molten metal - The number of molten metal drops required to heat the glove sample to a given level (performance level 0-4)
| Number of Drops | Level |
|---|---|
| > 35 | 4 |
| > 25 | 3 |
| > 15 | 2 |
| > 5 | 1 |
- f. Resistance to large splashes of molten metal - The weight of molten metal required to cause smoothing or pin-holing across a simulated skin placed directly behind the glove sample (performance level 0-4)
| Gram | Level |
|---|---|
| 200 | 4 |
| 120 | 3 |
| 60 | 2 |
| 30 | 1 |
