What Is UL Testing?

UL Testing refers to evaluating products to the applicable UL standards to determine compliance.

But here’s what many don’t realize: – UL is just one of several NRTLs (Nationally Recognized Testing Laboratories) – OSHA allows any qualified NRTL to perform testing and certification to UL/ANSI standards.

That means testing by UL is not mandatory — you can choose MET Labs and still meet all legal and regulatory requirements.
