The NVLAP Asbestos Fiber Analysis program provides assurance that laboratories are competent to analyze asbestos samples using polarized light microscopy (PLM) and/or transmission electron microscopy (TEM). The Asbestos Hazard Emergency Response Act (AHERA), enacted in 1986, requires that laboratories that analyze asbestos samples taken from public, or private, elementary or secondary schools, to be accredited by the National Institute of Standards and Technology (NIST) National Voluntary Laboratory Accreditation Program (NVLAP).
