UL Mark

UL (Underwriters Laboratories) is a leading company in terms of product safety. It provides the highest standards for products carrying their mark through testing, certification, and inspection. UL aims to ensure both workers’ and customers’ safety. Products that pass the UL certification procedure can be recognized by the affixed UL mark. It is particularly intended for products sold in the US and Canada.

The role of the UL mark

UL doesn’t only certify products but also facilities, processes, and systems. Altogether, it issued over 100 different standards.

The UL mark has a few different forms:

  1. UL Listed is for manufacturers whose products fulfill UL’s standards; it provides the authorization that allows the manufacturers to test the products and apply the UL mark themselves.
  2. UL Recognized is for goods that are used to manufacture another product; it indicates that the product can be safely used in further production. This mark is rarely seen on the finished product.
  3. UL Classified can be placed on a product by a manufacturer whose produced goods comply with UL’s standards and who cooperates with UL to ensure the quality and accuracy of their products.
