The process of obtaining a certification doesn’t stop when a product leaves our testing laboratories. Once you have completed your project and achieved UL Certification, our ongoing onsite certification inspection, known as the Follow-Up Services program, begins at the locations you identify as authorized to manufacture your product. The Follow-Up Services program is designed to validate that a manufacturer continues to produce UL Certified products that comply with requirements. This work takes place through factory inspections and audits at locations where UL Certified products are manufactured and the UL Mark applied.
When will onsite certification inspections start?
While certification testing in the laboratory provides an initial assessment of compliance, our industry-leading Follow-Up Services program continues to determine compliance long after a product has left our testing facilities.
These ongoing certification services take place through inspections and audits at locations where UL Certified products are manufactured, assembled, fabricated, processed, finished, or where products are stored or labeled with UL Marks.
Our ongoing certification services focus on examining both completed end products as well as the components that comprise those finished products. Component safety is a foundational element of the overall safety of a finished product and is critical in getting safer, compliant products to market.
Key elements of onsite certification inspections
A key element of our ongoing certification requirement is the factory inspection to confirm the certified product being manufactured is the same (or meets the requirements) as that assessed in the original evaluation.
If a product bears a UL Mark, a manufacturer must be able to provide verification that the product is constructed to meet the Follow-Up Service Procedure requirements. This is to be confirmed during the Initial Production Inspection.
In addition, a key element in determining compliance with UL Solutions requirements is confirming that materials and components used in UL Certified products are consistent with their descriptions in UL Solutions Follow-Up Services procedures, such as use of UL Listed or Recognized components. This is determined by review of component markings and appropriate component traceability.
When construction changes to UL Certified products are necessary you may submit your request to your local UL Solutions field engineer for assistance. Visit our Customer Guide To Submitting Revisions To UL Solutions webpage to learn more.
