CERTIFICATION MARKS A ULC or UL mark on a product means that ULC or UL has tested and evaluated representative samples of that product and determined that they meet ULC/UL's requirements. In addition, products are periodically checked by ULC/UL at the manufacturing facility to make sure they continue to meet ULC and/or UL requirements. Show the ULC Mark A guide on how to accurately promote your ULC product certification. Mark Acceptance Booklet For more information about ULC or UL marks,

Field Evaluated Product Mark
A Field Evaluated Product Mark is applied to a product that is thoroughly evaluated in the field instead of UL's laboratories or the manufacturer's facility. If a product has been significantly modified since its manufacture or the product doesn't bear any third-party certification mark, a building owner, a regulatory authority, or anyone else directly involved with the product can request that UL conduct tests in the field on the specific piece of equipment. Products that meet appropriate safety requirements are labeled with a tamper-resistant Field Evaluated Product Mark.
|  | Marine Mark
The UL Marine mark appears on products that have been evaluated specifically for marine use. Products bearing this Mark have been evaluated to UL's published Marine Safety Standards and other applicable standards and codes. These requirements address hazards that can occur as a result of exposure to harsh marine environments such as vibration, shock (impact), ignition protection, water ingress and salt spray corrosion common on pleasure craft and boats. Examples of the type of equipment suitable for the UL Marine Mark include alternators, battery chargers/power inverters, navigation lights, and fuel tanks, filters and pumps. |
