Are aftermarket power cords required to be UL / CE approved?


Lots of folks are making and selling aftermarket power cords. In the US are these cords required to be UL or CE approved?

 Wondering about the ramifications of using unapproved cords. Am I liable if someone gets shocked, could my home owners policy deny a claim if they determine a non approved cord started a fire?

So of course everyone gets their panties in a bunch over electricity.
You wear panties?
A simple amp mod question a while back generated:
1. You’ll kill yourself
2. Even if you unplug it (!)
Sorry, but you don't know what you're talking about. Components that are unplugged can still contain lethal voltages. That's especially true of amplifiers, but can also be true of things such as preamplifiers.
Oh for the days when Ben Franklin flew a kite attached to a metal key up into a thunderstorm!
Yes, and Franklin did it in pantaloons!!!                            When men were men.
A fire is a fire and HO insurance will cover it. The only way they won't is if you lit the match and started the fire. If the power cord caused it, they will go after the manufacturer for reimbursement (subrogation).

I ride bicycles, a lot. I’ve tumble over four time over the past twenty years, each time I bonked my head on the pavement; fortunately I was wearing a helmet each time I wiped out. Wearing a helmet can save you from a serious concussion or worse.
