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.
