NRTLs is simply a shorter way to say Nationally Recognized Testing Laboratories. And of those that exist, the three major NRTLs are UL (Underwriters Laboratories), ETL (once ETL Labs –Electrical Testing Laboratories—now the mark of Intertek), and CSA (Canada Standards Association).

All three of these marks represent an independent and globally recognized laboratory dedicated to the safety of technologies. The common thread all these laboratories have is that they test and help regulate the safe implementation of electrical technologies. From computers to the electronics in vehicles, there laboratories have a hand in it all. In fact, if you’re reading this on a mobile device or a laptop, take a second to look underneath the keyboard or on your tablet or phone and see if you can find one of these insignias somewhere embedded in the plastic. Likely case is that you’ll see one of them, if you’re using a reputable product manufactured in the US or Canada, that is.

UL, ETL, and CSA help to ensure that the product in your hands is safe and efficient. In order to land one of these certifications, manufacturers undergo rigorous measures to meet the guidelines of safety and quality set by these laboratories. Some companies and manufacturers choose to work outside of their guidelines, but if they do, they can’t ensure that they are offering their customers a safe and reliable product.

This is why it’s important for consumers to understand the value of a product that harbors one of these stamps of approval. Any product with a UL, ETL, or CSA stamp means that it has undergone the nationally and globally-recognized standards for health, safety, and environmental concerns.  Any electrical product you buy or operate should have one of these marks on it.
