un-witnessed product safety testing

For Your NRTL Mark, Why Un-witnessed is the Way to Go

Written by Michael Proffitt on . Posted in Testing

Don’t confuse un-witnessed NRTL Product Safety testing with a blind taste test. There is nothing blind about un-witnessed product safety testing. Nothing is covered up, no mystery revealed.

A blind taste test is based on faith. Un-witnessed product safety testing is based on trust.

Trust. It’s what you want to give, and receive, from a business partner. A compliance testing partner is no different.

A small number of product testing labs in the U.S. operate with the trust of leading international safety agencies to perform un-witnessed product safety testing on information technology equipment (ITE), such as wireless devices, telecommunications equipment, network routers, office scanners and more.

What does that mean to you?

It means you can have it both ways. You get the trusted certification mark that is accepted the world over, but get to work with a third-party independent laboratory who is strictly focused on providing you the level of service you expect. When a world-class certification company, like Underwriters Laboratories (UL) or TUV SUD entrusts a partner to conduct testing on their behalf, you can trust that the same rigor and exacting standards will be brought to the process as if the agencies’ own engineers were on site.

Other benefits of un-witnessed product testing include:

  • The testing process is quicker and more efficient without an agency engineer on site
  • Testing can be organized around your schedule, not around the availability of the licensing agencies
  • Communications between your team and the testing lab are direct, without third-party involvement

ITE Testing

Of course, you can’t be expected to enlist a compliance testing partner without some background into the major testing agencies and their roles in ensuring thorough and comprehensive testing of ITE.

Underwriters Laboratories, or UL, is a leading global independent safety science company focused on promoting safe living and working environments. The UL Mark on your product means that it meets the highest degree of safety standards in the industry. A UL-approved test lab carriers the Engineering Agent or “EA” certification.

TUV SUD is a world leader in product certification and testing to international standards. It issues TUV SUD certification marks based on standards set according to internationally recognized benchmarks.

They both set the bar high, so when they entrust a company to conduct unwitnessed product testing on their behalf, you can trust that the quality will be world-class.
