After being continuously applied the maximum
allowable voltag e at 85 ± 2°C for 1000 hours,
the specimen shall be stored at room
temperature and normal humidity for 1 to 2
hours. Thereafter, the change of Vv shall be
measured.

stored at room temperature and normal humidity
for 1 to 2 hours. Thereafter, the change of Vv
shall be measured.

sequence The specimen shall be subjected to:
a) dry heat at +85°C, 16 h
b) damp heat, 1st cycle: 55°C, 93 % r.H., 24 h
c) cold, -40°C, 2 h
d) damp heat, additional
5 cycles: 55°C, 93 % r.H., 24 h/cycle
Then the specimen shall be stored at room
