SWG CUL and UL Approved? What do these mean?

[Aquatica]

Hi,

I guess I should know what these two mean as we sell SWG's approved by them.

I know what NSF means but anyone know what these other two are? Organizations? Can't seem to find them online.

This SWG is Hayward AquaRite.

if anyone can shed some light on what these mean it would be much appreciated.

Thanks!

UL is underwriters laboratory. The C means different things depending on how it's used.
