Underwriters Laboratories

Confidentiality is a very important aspect of our work at Underwriters Laboratories Inc. (UL) and is outlined in the application form that UL sends to customers at the beginning of projects. Furthermore, UL employees must sign an application form which contains a confidentiality clause when applying for employment at UL.

Data developed during the course of an investigation is proprietary. UL signs a contractual agreement with all customers stating we will maintain confidentiality and refrain from disclosing third party information obtained in confidence. You can, however, purchase a copy of the appropriate Standard that indicates the requirements a manufacturer of a particular product will have to meet in order to obtain UL Listing, Recognition or Classification.
