The voltage shall be applied through a protective series TEMPERA TURE CYCLING & HUMIDITY HUMIDITY:: TEMPERATURE resistance not exceeding 1 megaohm. The The capacitor at approximately 75% of the electrification time shall not exceed 1 minute. guaranteed maximum capacitance, shall be given a treatment consisting of 5 temperature DIELECTRIC STRENGTH: The capacitor, cycles as follows: Cool the capacitors to -55°C set at approximately maximum capacitance, ±3°C. Remove the capacitor from the cooling shall withstand voltage between terminals for chamber and allow to reach room temp. 1 to 5 sec. as indicated for the respective style. The surge current shall be limited to 50mA maximum. TORQUE: When measured 25°C ± 5°C, the torque required to start and maintain rotation of the rotor through one full turn, shall be as indicated for the respective style. TEMPERATURE TURE CHARACTERISTIC: The TEMPERA T.C. of capacitance shall be within the limits shown in the table to the right. The T.C. shall be determined by measuring the capacitance (capacitor shall be set at approximately 75% of the guaranteed maximum capacitance) at +25, -55°C and either +85°C or +125°C, whichever is applicable to the respective style, at a frequency of 0.1 to 1 Megahertz. Each measurement shall be made after the capacitor has reached thermal stability.

Remove from oven and allow capacitor to cool to room temperature. The capacitor shall be held at the specified minimum and maximum temperatures long enough to reach equilibrium and in no case less than 15 minutes. The rate of change of temperature in cooling from room temperature, or heating above it shall not be less than 3°C per minute. The temperature cycles shall be followed by exposures for 96 hours to a relative humidity of 95% at 40°C ±3°C. The capacitor shall then be removed from the humidity chamber and held at 25°C ±5°C with a maximum humidity of 50% for four hours. The I.R. shall be at least 1 gigaohm, the “Q” at 1 MHz is at least 40% of initial test limit and the capacitance shall not have changed by more than ±3% or ±0.5pF, whichever is greater, from its value prior to the start of the temperature cycling.
