UL Safety Tests

UL safety testing services are organized into sections that evaluate specific product types. To establish recognition, manufacturers are asked to provide samples for evaluation in accordance with specific UL standards.

EUROLAB performs the feasible evaluation and testing of these samples, then combines the data package for UL inspection. Following compatible results, UL evaluates the test data and makes the final determination of whether a product is suitable for recognition. Upon review and acceptance of test data by UL, the manufacturer is issued with the Authorization Statement (NofA) to apply the UL certification mark to their products.
