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 ...
Green Tea standard reference. Certified reference materials (CRMs) are 'controls' or standards used to check the quality and metrological traceability of products, to validate analytical measurement methods, or for the calibration of instruments. [1] A certified reference material is a particular form of measurement standard.
NIST is also required by statute to consult with the NSA." [53] Recognizing the concerns expressed, the agency reopened the public comment period for the SP800-90 publications, promising that "if vulnerabilities are found in these or any other NIST standards, we will work with the cryptographic community to address them as quickly as possible ...
