100 times that, compared to safety certification like IEC61508 and all its offsprings (ISO26262 for automotive) UL and CE are a walk in the park, it’s just a whole different level of complexity, not only the design must be safe, also the whole development cycle must be certifiable. That means all decisions pertaining anything even remotely related to safety need to have a full paper trail behind them justifying why the decision has been taken, how, potential safety risks, etc.

The cost of all the process is also much higher as a result, however there is a good reason for it, safety regulations are written in blood...
