How the DPL Seal of Approval Program Works

Brand-name product companies who desire a DPL Labs’ Seal of Approval provide multiple samples of each product model that they want tested. DPL Labs subjects each sample to a rigorous multi-element testing regime to determine the product’s actual performance.

Helping Industry Build Better Products

Pass or fail, DPL Labs’ engineers generate an extensively detailed report on how each product model performed. These reports show precisely how each element of that product tested and, if necessary, exactly where it failed. Many participating companies have taken this information and used it in engineering future products that perform even better.

These tests are tough!

We have seen many products fail our testing process as only the best can pass the test. To receive a DPL Labs’ Seal of Approval, the product must meet or exceed by a substantial margin DPL’s minimum standards. Only top quality products are able to earn a Seal of Approval.

DPL Secret Shoppers

And even those who do pass these rigorous tests aren’t out of the woods yet. At regular intervals, DPL Labs secret shoppers purchase samples of approved products in the field from retailers that consumer’s frequent. These samples receive follow-up testing to be sure that products actually delivered to consumers are of the same level of quality as the originally tested samples.
