Asbestos testing is a very important process, since people know the dangers of this mineral (asbestos is a group of fibrous metamorphic minerals of the hydrous magnesium silicate variety). Most asbestos fibers are invisible to the human eye because their size.
Asbestos testing is necessary, because you can't tell whether a material contains asbestos simply by looking at it, unless it is labeled. If in doubt, treat the material as if it contains asbestos or have it sampled and analyzed by a qualified professional. A professional should take samples for analysis, a professional knows what to look for, and because there may be an increased health risk if fibers are released.
Asbestos testing should always be done by an expert.
For asbestos testing the requirement of EPA is the polarized light microscopy (PLM asbestos test method) analysis with specialized microscopes. The results of asbestos testing establish the percentage and type of asbestos present in the sample material.
The Environmental Protection Agency (EPA or sometimes USEPA) is an agency of the federal government of the United States charged with protecting human health and with safeguarding the natural environment: air, water, and land. The EPA began operation on December 2, 1970. The current Administrator (as of 2006) is Stephen L. Johnson.
Asbestos Fiber Analysis (PLM Test Method)
The purpose of the Bulk Asbestos Program is to accredit testing laboratories to assure that they are competent to analyze bulk samples for asbestos testing, using polarized light microscopy (PLM).
National Institute of Standards and Technology (formerly the National Bureau of Standards) develop an accreditation program for laboratories conducting analyses of bulk samples of asbestos-containing material.
