Our Data Acceptance Program (DAP) provides a means for UL to accept externally generated test data in support of UL Mark certification. Our product investigations typically involve testing of product samples. While we maintain extensive test facilities, customers can also utilize their own or third-party facilities for product testing via this program.
Participating test facilities are required to have the appropriate physical resources, equipment and qualified personnel needed to conduct testing, equivalent to what would be used in our own laboratories for the same testing. Additional programs (such as TCP and PPP) allow the customer to conduct a large portion of the engineering evaluations on behalf of UL.
After a data acceptance program is established, we will reassess a test laboratory annually. We thoroughly review and audit all data submitted before they are used for certification. The TCP and PPP programs offer the additional engineering element that will require the customer engineers to undergo a technical review of the UL Standard.
Our Data Acceptance Program provides qualified customers a number of advantages. The largest advantage is the increased control over the timing and scheduling of their product testing and certification program. The number one delay for projects is a non-conforming test result. Having the ability to identify these issues and have their engineering team available at the test location results in faster resolution.
Providing us with a data-sheet-ready package at the time of submittal eliminates test time and allows us to decrease the turnaround time for DAP participant's projects. Our customers see an increase in delivering speed, market access and flexibility. Conducting testing at your site on your own schedule is a more flexible way to enable your business to obtain our market-leading certifications for your products.
