- Abstract
- The ignition of television receivers initiated by electrical failures in the circuitry was examined by studying four receivers. They were: two black and white portables, a color portable, and a color console receiver. Selected locations within the circuitry were stressed by introducing full or partial short circuits to simulate the failure of electronic components. The temperatures and increased power dissipation generated by short-circuited components were recorded. Although component temperatures greater than 500 deg. C were achieved, no flaming ignition sources were generated. For comparative purposes the energy release rate of the ignition source specified in the UL 1410 test procedure was measured. Supplemental measurements on the operating temperatures of chassis components under varying ventilation conditions were also made.
