Testing & Reporting Requirements for Hazardous Location Lighting
Products intended for Hazardous Locations are eligible for listing on the Qualified Products List. Under Technical Requirements V5.1 (as well as previous versions), they may qualify either within an existing Primary Use Designation, or by using the provisions for Specialty designations. Under this policy and Technical Requirements V5.1, products seeking qualification on the QPL that would like to identify themselves as suitable for Hazardous Locations using the Specialty designations must provide documentation as described below to demonstrate the appropriateness of their products for Hazardous Locations. Products seeking qualification on the QPL using an existing Primary Use Designation do not need to provide additional documentation.
Please review the FAQs page for additional policy clarifications.
Supporting Documentation Requirements
In addition to all other requirements, products seeking qualification on the DLC QPL with “Hazardous” descriptor terms under a Specialty Primary Use Designation, including, but not limited to: Outdoor, Specialty: Hazardous Wall-Mounted Luminaire; Outdoor, Specialty: Hazardous Area Lighting; Outdoor, Specialty: Hazardous Flood/Spot Lighting; and Indoor High-Bay, Specialty: Hazardous High-Bay Lighting, must provide the following supporting documentation:
- Certification of Compliance, Notice of Authorization to Mark, or lab-specific directory listing from an applicable safety organization
The documentation must explicitly state that the model numbers in question are certified to the UL844 standard and include the Class and Division to which the products are certified. In situations where questions arise, the DLC will require that the documentation from the applicable safety organization clearly indicate both the model numbers in question, and the certification to the UL 844 standard.
Testing must be performed by an appropriate safety organization in the US or Canada (i.e. OSHA NRTL or SCC-recognized body). The DLC describes certification organizations that are acceptable for purposes of the DLC safety certification requirement in the Safety Certification Requirements section of the website.
