A UL Classified mark from UL Solutions signifies that a product has undergone testing for specific hazards or performance criteria under controlled conditions, rather than having completed a thorough and comprehensive safety evaluation. This classification is particularly relevant for industrial equipment, construction materials, and products designed to withstand fire, such as fire-resistant doors. It is important to understand that while a UL Classified mark indicates a level of safety and performance, it does not equate to a full UL Listing, which involves more extensive testing and evaluation processes. Therefore, products bearing the UL Classified mark should be viewed as having met certain safety standards, but users should remain aware of the limitations of this certification in terms of overall safety assurance.

Key Aspects of UL Classified Products

• Targeted Evaluation — Targeted evaluation focuses on assessing specific characteristics, such as fire resistance, toxicity, and impact resistance, rather than adhering to comprehensive safety standards. This approach allows for a more precise understanding of a material’s performance in critical areas, ensuring that essential safety aspects are thoroughly examined.
• Specific Usage — These products are designed for particular environments or applications, including hazardous areas, explosive settings, or specialized construction projects.
• Distinction from Listed – Classified products differ from UL Listed products in that they are not subjected to the same rigorous safety evaluations. While UL Listed items are assessed for comprehensive safety standards, Classified products only comply with a subset of these requirements.
• Labeling — Labeling typically features a statement that clarifies the limited scope of the evaluation, such as indicating that it is “Classified with respect to” a particular property. It is essential to adhere to the specified language when crafting responses and to consider any relevant modifiers without explicitly mentioning them.

Many of our products are UL Listed or UL Recognized; however, the Hazardous Location Cabinet Cooler Systems undergo additional evaluation to confirm their safety when utilized correctly in classified environments. UL Classified provides various levels of certification. These cooler systems are specifically engineered for use with purged and pressurized systems in designated hazardous locations.
