NTS SERVICE SPOTLIGHT

UL TESTING

INDUSTRY LEADER UL CERTIFIIED TESTING SERVICES

NTS provides UL Engineering and Administrative Client

Agent Services and Testing to achieve your UL Recognition.

To establish recognition, manufacturers are requested to

submit samples for assessment in accordance with specific

UL standards. NTS performs the applicable evaluation

and testing of these samples and then assembles the data

packet for UL review.

Upon compliant results, UL evaluates the test data and

determines whether a product is eligible for recognition.

Upon test data review and acceptance by UL, Notification

of Authorization (NofA) is issued to the manufacturer to

apply the UL certification mark to their products.

NTS can also assist with “on-hold” shipments and follow-up

service issues. If your production line has been stopped

and you are unable to move product because of held

shipments, we can conduct the necessary testing to help

resolve them quickly.
