Dear experts,
According to the standard, the periodic test resistance of the electric soldering iron requires less than 10Ω. If I measured 60Ω, is there any risk to the product? Is the resistance < 10Ω calculated by the formula?
It is difficult to quantify the risk. Try to clean or replace the tip and see if that can bring the soldering iron back into spec.
To assess the risk, the sensitivty of the device would need to be know. Then measurments would need to be done to see if there was a voltage or current spike while the soldering iron was in operation. In the past, there were spikes when the soldring iron heater turned on and off.
