| Burner | acc. to IEC 60332-1-1 | acc. to IEC 60332-2-1 |
| Test temperature | 1 kW flame | defined by the stipulated setting of the flame length |
| Position of specimen | vertical | vertical |
| Position of flame | 45° to vertical specimen | 45° to vertical specimen |
| Duration of flame | see table 1 | 20 seconds |
| Conditions | Cable must be self-extinguishing. The damage or carbonization may only reach max. 50 mm under the upper fixing clamp. Additionally in order to pass the test the distance from the upper beginning of carbonisation above the point of flaming to the bottom start of carbonisation (below the point of flaming) shall not exceed 425 mm. If the carbonisation expands more than 540 mm from the lower end of the upper fixing downwards, an additional fault has to be recorded. | Cable must be self-extinguishing.

Outer diameter* of specimen in mm | Duration of flaming in seconds |
|---|---|
| D ≤ 25 | 60 |
| 25 mm < D ≤ 50 | 120 |
| 50 mm < D ≤ 75 | 240 |
| D > 7D > 75 mm | 480 |
* If cables or insulated cables are tested that are not round (e.g. flat twin cables), their dimension is to be measured and an equivalent diameter must be calculated from this.
