1. Asbestos Testing: A state-by-state directory of accredited testing laboratories is available at the website of the National Institute of Standards and Technology, which is part of the US Department of Commerce. Find a lab near you to perform Asbestos Fiber Analysis (PLM Test Method). Also has information on labs in Canada.
