I know UL, but what is ETL?
ETL is a competitor of UL. Same kinds of testing; just a different test
lab (and usually cheaper). Both UL and ETL are independent testing
companies. You pay them to test your product. They are more or less
interchangeable.
UL and ETL are "brand names" for testing laboratories. Just as "Coke"
and "Pepsi" are simply brand names for carbonated soft drinks.
Unfortunately, many people use brand names to refer to generic product.
That's the power of advertising. Similarly, UL advertises its brand name
much more aggressively than ETL. Regulations *shouldn't* be written to
require a certain brand name product; but sometimes they do. That's how
you get rules that say "must be UL listed" when they really mean "must
be safety tested and listed by a recognized independent testing agency".
