Under ambient temperature in excess of 70°C, the
load shall be derated as shown in the figure below.
Resistors shall have a rated direct current (DC)
continuous working voltage or an approximate sine
wave rootmean square (rms) alternation-current
(AC) continuous working voltage at commercial line
frequency and wave form corresponding to the power
rating, as determined from the following formula:
Where,
The resistors shall be marked with color codes as per EIA-172.

Initial resistance shall be measured. Resistors
shall be placed in a chamber at relative humidity
of 90 - 95% at ambient temperature of 40 ± 2°C.
1-1/2 hr. (on), 1/2 hr. (off) for a total of 1,000 hrs.
After removal from the chamber, the resistors shall
be allowed to dry at room ambient for approxi-
mately 1 hr. Final resistance shall be measured.
Initial resistance shall be measured. Resistors
shall be placed at ambient temperature of 70 ±
3°C. Then DC RCWV shall be applied intermittent-
ly 1-1/2 hr. (on), 1/2 hr. (off) for a total of 1,000 hrs.
After return to room temperature, final resistance
shall be measured.
Then DC RCWV shall be applied intermittently
