National Voluntary Laboratory Accreditation Program

National Voluntary Laboratory Accreditation Program (NVLAP) is a National Institute of Standards and Technology (NIST) program in the USA which provides an unbiased third-party test and evaluation program to accredit laboratories in their respective fields to the ISO/IEC 17025 standard. NVLAP is in compliance with ISO/IEC 17011.
