The National Institute of Standards and Technology (NIST) administers the National Voluntary Laboratory Accreditation Program (NVLAP). NVLAP provides accreditation services through various laboratory accreditation programs (LAPs), which are established on the basis of requests and demonstrated need. Each LAP includes specific test or calibration standards and related methods and protocols assembled to satisfy the unique needs for accreditation in a field of testing or calibration. NVLAP accredits public and private laboratories based on evaluation of their technical qualifications and competence to carry out specific calibrations or tests.
ELAP currently grants certification to commercial, facility self-monitoring and government operated environmental laboratories, in the following fields of accreditation:
- NVLAP PLM #500097-0View
- NVLAP PLM #201076-0View
- NVLAP PLM #200860-0View
