* Resistance to pulse: change shall be ±5% of the pre-test values. 1 sec. ON, 1 second OFF, 20,000 cycles.

The voltage is applied with maximum pulse voltage.

Resistors shall be maintained within ± 1°C at the

ambient temperatures listed below. The use of

forced circulating air is recommended to assure

temperature stability and uniformity. Resistance

measurements shall be made at each temperature

15 minutes after air temperature has stabilized at

the specified temperature.

The percent difference in resistance referred

to the resistance at +25°C shall be computed with

the following formula:

Percent Resistance = (R-r) x 100

Where: R is the resistance at test temperature

r is the resistance at +25°C
