Perseverance Tester - For Electrical Lab Training The capacity of an electric iron to give an adequately long working life is controlled by supporting the iron under test on three metallic legs over a metal plate, squeezing a thermocouple intersection at the mid-purpose of its sole plate, and working it at 1.15 times its appraised contribution for 200 working hours in cycles comprising of 11 hours On period and 1 hour Off period. The normal temperature of the sole plate amid this period is kept up at around 200°C for thermostatically controlled irons and in the vicinity of 205°C and 260°C for common irons, the last by fitting cooling if essential. Toward the finish of the above trial, the iron is analyzed for its electric quality and presentation of any live parts caused by breakage or twisting of the walled in area. The Endurance Tester for electric irons comprises of a control board to give single-stage supply at 1.15 times the evaluated contribution to the iron under test in cycles of 11 hour On period and 1 hour Off period, and a reasonable help for putting the iron under test on amid this period..
