1. Preconditioning, class 2 only:
150 +0/-10 °C /1 hour, then keep for
24 ±1 hour at room temp
2. Initial measure:
Spec: refer to initial spec C, D, IR
3. Damp heat test:
500 ±12 hours at 40 ±2 °C;
90 to 95% R.H. 1.0 Ur applied
4. Recovery:
Class 1: 6 to 24 hours
5. Final measure: C, D, IR
P.S. If the capacitance value is less than the minimum
value permitted, then after the other measurements
have been made the capacitor shall be preconditioned
according to “IEC 60384 4.1” and then the requirement
shall be met.
No visual damage after recovery

Class 1:
NP0: ≤ 2 x specified value
Rins
Class 1:
NP0: ≥ 2,500 MΩ or Rins x Cr ≥ 25s
whichever is less
