UL Testing
Microtek Laboratories provides UL Engineering and Administrative Client Agent Services and Testing to achieve your UL Recognition.
UL’s testing services are organized into sections that evaluate specific types of products. To establish recognition, manufacturers are requested to submit samples for assessment in accordance with specific UL standards. Microtek Laboratories can perform the applicable evaluation and testing of these samples and then assemble the data packet for UL review. Once the analysis of the testing results is complete, UL makes the final determination as to whether or not the product is eligible for recognition. If acceptable, UL will authorize the manufacturer to apply the certification mark to their products.
Microtek’s staff includes experienced engineers and technical support personnel. Reviewing your requests, examining how products are constructed, conducting tests, evaluating data, submitting test results and coordinating with the UL staff are a few of our responsibilities.
