The Difference Between a Recognition and a Listing in the Electrical Industry
Below is a transcript of this video clip.
First, we want to talk about what a recognition is compared to a listing. A recognition is for a component that's intended to be used with or within another system. It's not necessarily a standalone product. Think of potentially a power supply that's intended to be used within some other product. That is a recognition. It's all the recognition because it's only been evaluated for some of the standard requirements as not everything within the standard would be applicable for a component. And so when that component is being used in another product, it requires a full review and evaluation of that component within the end product and evaluation for use.
And along with that comes the conditions of acceptability of that recognized component. How is it tested? How is it evaluated? What are the limitations of that recognition? What else needs to be considered? What is being used in a final product. And on the other side is the listing side. So that would be a finished product that has been evaluated for all of the requirements of a standard, and it's the end user's responsibility to use that product in a way that's in line with the certification and its intended use.
