UL Mark Surveillance Requirements
UL's Follow-Up Services program is fundamental to the integrity of UL's certification Marks. For a product to bear a UL certification Mark, it must comply with applicable UL requirements when initially evaluated and ongoing production of products intended to bear a UL certification Mark must continue to comply with all applicable UL requirements.
To help achieve consistent and ongoing compliance, manufacturers must be aware of current requirements as documented in UL's Follow-Up Services Procedures, applicable standards and other UL Follow-Up Services program publications. To facilitate a common understanding of UL Mark Surveillance Requirements, UL has developed the UL Mark Surveillance Requirements document.
This document harmonizes these general requirements into a single document that can be readily accessed by both customers and UL staff. The requirements in this document apply to all customers participating in UL/C-UL/ULC Mark product certification programs also referred to as UL certification Mark programs. The requirements described in this document are based on terms and conditions covering UL's delivery of services and reflect UL's long-standing Follow-Up Services inspection program requirements for the UL certification Mark programs.
