Following the 48-hour period and while still exposed to moist air, the device shall comply with the requirements for dielectric voltage-withstand between current-carrying parts and accessible non-current-carrying metal parts in accordance with Clause 8.6 and operate normally. Alternate chamber conditions may be 88 ±2 % at a temperature of 32 ±2 °C or 93 ±2% at a temperature of 28 ±2 °C. * k9 Q) Q2 r- L, M% d. t" e5 w
