National Voluntary Laboratory Accreditation Program

Because laboratory testing often applies to articles in international trade, international accreditation is often sought. There are many international accrediting agencies in existence. Two examples are the National Institute for Standards and Technology (NIST) and the American Association for Laboratory Accreditation (AALA). NIST administers what is called the National Voluntary Laboratory Accreditation Program (NVLAP).

Each country has its own accreditation body for laboratories. In the United States, NIST is administering the National Voluntary Laboratory Accreditation Program (NVLAP) [109]. The criteria for accreditation used by NVLAP is consistent with ISO Guide 25, which involves the following items (1) quality system, (2) staff competence and training, (3) facilities and equipment, (4) calibration and traceability, (5) test methods and procedures, (6) recordkeeping, and (7) test reports.

The personnel monitors normally used for individual monitoring must be processed by a dosimetry processor holding personnel dosimetry accreditation from the National Voluntary Laboratory Accreditation Program (NVLAP) of the National Institute of Standards and Technology for the type of radiation or radiations included in the NVLAP program that most closely approximates the exposure characteristics for the individual wearing the dosimeter. 

Third-party accreditation is now increasing in popularity. Some laboratories now have quality systems registered to ISO 9000 series standards, and third-party accreditation for laboratories based on ISO 17025 has now become widely used through the National Voluntary Laboratory Accreditation Program (NVLAP) administered by the National Institute of Standards and Technology and the A2LA scheme of the American Association for Laboratory Accreditation.
