BR MODEL

Short term electrical power surge: cyclical electrical surge of resistor – 80 cycles with t = 50 s and 6.25 NP (0.1 t = on; 0.9 t = off)

Stability: resistor charge for 1000 h with NP; 0.7 NP or 0.2 NP

Long term climatic test: charge of the resistor at 40°C and 93% relative humidity over 56 days with NP;

Temperature change test: cyclical charge of the wire resistor for 5 periods

Higher temperature: 155°C 30 min.

Lower temperature: -55°C 30 min.
