TEST CONDITIONS FOR FIW ACCORDING TO UL 2353 (UL 60950)
UL 60950 is replaced by UL 62368.
UL 2353, which is very similar to the expired IEC 60950 Annex U, primarily describes electrical properties, mostly based on short-term tests.
| Test conditions | acc. to UL 2353 No. |
Typical values for 0.30 mm FIW 6 |
|---|---|---|
| U2.1 Electrical Strength | 9 | 6000 Vrms 1 min. (twisted pair) |
| U2.2 Adherence and Flexibility | 10 | 3000 Vrms 1 min (mandrel) |
| U2.3 Heat Shock | ||
| 225 °C x 30 min for Class B | 12 | 3000 Vrms 1 min. (mandrel) |
| 240 °C x 30 min for Class F | ||
| U2.4 Retention of electrical strength after bending | 11 |
3000 Vrms 1 min. (mandrel) |
