Actual testing time depends on the test methods used. For many products, it may be completed in as little as one day, while for those with lifetime tests, such as performance testing for lighting products or solar maintenance testing for roof products, testing may take from several months to three years.
Product certification depends on the certification body review time. It may be completed in as little as two or three days if the certification body (CB) has all of the information it needs from the manufacturer, but usually, it takes about two weeks.
For more information, please feel free to contact an appropriate EPA-recognized laboratory or CB.
