EN 407:2020 — Heat & Flame-Related Performance (A–F)
Understand the standards behind professional hand protection.
With flame / burning behavior tested
Understand the standards behind professional hand protection.
No flame test claimed
Understand the standards behind professional hand protection.
| Index | Hazard | Levels (summary) | What higher levels imply (general) |
|---|---|---|---|
| A | Limited flame spread (afterflame / damaged length) | 0–4 | Better resistance to ignition and flame propagation on the specimen. |
| B | Contact heat | 0–4 | Ability to extend time before pain threshold at defined contact temperature. |
| C | Convective heat | 0–4 | Insulation against hot gas/convective oven conditions in the test. |
| D | Radiant heat | 0–4 | Insulation against radiant heat flux in the test apparatus. |
| E | Resistance to small splashes of molten metal | 0–4 | More / hotter small droplets required to damage the heat-sensitive PVC film in test. |
| F | Resistance to large splashes of molten metal | 0–4 | Performance against larger molten metal splash mass in the test. |
EN 511:2006 — Protection Against Cold
Cold performance is shown as three values: convective cold, contact cold, and water penetration. Higher convective/contact classes indicate better insulation under the standard’s conditions.
The snowflake pictogram accompanies gloves tested to EN 511. The three numbers align to: convective, contact, and water penetration.
| Column | Property | Scale | Notes |
|---|---|---|---|
| 1st | Convective cold | 0–4 | Insulation vs convective cooling on a heated hand form (higher = better insulation). |
| 2nd | Contact cold | 0–4 | Resistance to heat transfer when gripping a cold cylinder (higher = better). |
| 3rd | Water penetration | 0 or 1 | 0 = water penetration after 5 min; 1 = no penetration within test time. |
