Pre-certification reviews, also known as gap assessments, Stage 1 assessments, proactive reviews or preliminary reviews, are conducted by UL technical experts early in the design process either at the UL test facility or on site at a manufacturer's facility, typically to assess conformity to applicable standards for the desired markets. This service does not result in a UL certification.
Customers can arrange for a pre-certification review as early as the design concept stage and straight through to the last stages of the product development cycle. UL offers two service options: formal and informal.
Formal pre-certification reviews include a complete engineering evaluation of a product with a comprehensive report of the findings, providing actionable insight into how a product's construction may or may not meet the requirements of all applicable standards.
During an informal pre-certification review, a UL engineer provides expert insight, but no formal documentation (letter report) is issued. Informal pre-certification reviews can be conducted in person, over the phone or online via web chat.
