Reputable manufacturers go to great effort to acquire certification to demonstrate the safety of their products. However, less reputable manufacturers may forego testing and certification, using counterfeit marks to give the illusion that their products are on par with competitive products, when in fact, they could be dangerous and of unknown quality.
It’s important to understand how products and equipment are tested and certified, as inspectors regularly encounter installed products bearing a wide range of certification marks in day-to-day work.
