The National Voluntary Laboratory Accreditation Program (NVLAP), administered by the National Institute of Standards and Technology (NIST) in USA, offers accreditation for testing and calibration laboratories across various fields. NVLAP evaluates laboratories' technical qualifications and compliance with standards like ISO/IEC 17025. The accreditation process includes application submission, an on-site assessment, proficiency testing, and addressing any identified nonconformities. NVLAP’s accreditation is recognized internationally, indicating a laboratory’s competence but not certifying its performance. NVLAP’s mission is to deliver high-quality accreditation services and promote global acceptance of accredited results. ^[1]
