National Voluntary Laboratory Accreditation Program
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. Accredited laboratories Calibration *Dimensional *Electromagnetics - DC low frequency *Electromagnetics - RF/microwave *Ionizing radiation *Mechanical *Optical radiation *Thermodynamic *Time and frequency Chemical calibration *Chemical calibration: provide ...

National Institute Of Standards And Technology
The National Institute of Standards and Technology (NIST) is an agency of the United States Department of Commerce whose mission is to promote American innovation and industrial competitiveness. NIST's activities are organized into Outline of physical science, physical science laboratory programs that include Nanotechnology, nanoscale science and technology, engineering, information technology, neutron research, material measurement, and physical measurement. From 1901 to 1988, the agency was named the National Bureau of Standards. History Background The Articles of Confederation, ratified by the colonies in 1781, provided: The United States in Congress assembled shall also have the sole and exclusive right and power of regulating the alloy and value of coin struck by their own authority, or by that of the respective states—fixing the standards of weights and measures throughout the United States. Article 1, section 8, of the Constitution of the United States, ratified i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
ISO/IEC 17025
ISO/ IEC 17025 General requirements for the competence of testing and calibration laboratories is the main standard used by testing and calibration laboratories. In most countries, ISO/IEC 17025 is the standard for which most labs must hold accreditation in order to be deemed technically competent. In many cases, suppliers and regulatory authorities will not accept test or calibration results from a lab that is not accredited. Originally known as ISO/IEC Guide 25, ISO/IEC 17025 was initially issued by ISO/IEC in 1999. There are many commonalities with the ISO 9000 standard, but ISO/IEC 17025 is more specific in requirements for competence and applies directly to those organizations that produce testing and calibration results and is based on more technical principles. Laboratories use ISO/IEC 17025 to implement a quality system aimed at improving their ability to consistently produce valid results. Material in the standard also forms the basis for accreditation from an accreditati ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Common Criteria Testing Laboratory
The Common Criteria model provides for the separation of the roles of evaluator and certifier. Product certificates are awarded by national schemes on the basis of evaluations carried by independent testing laboratories. A Common Criteria testing laboratory is a third-party commercial security testing facility that is accredited to conduct security evaluations for conformance to the Common Criteria international standard. Such facility must be accredited according to ISO/IEC 17025 with its national certification body. Examples List of laboratory designations by country: *In the US they are called Common Criteria Testing Laboratory (CCTL) *In Canada they are called Common Criteria Evaluation Facility (CCEF) *In the UK they are called Commercial Evaluation Facilities (CLEF) *In France they are called Centres d’Evaluation de la Sécurité des Technologies de l’Information (CESTI) *In Germany they are called IT Security Evaluation Facility (ITSEF) Common Criteria Recognition Arra ...

ISO Standards
The International Organization for Standardization (ISO ; ; ) is an independent, non-governmental, international standard development organization composed of representatives from the national standards organizations of member countries. Membership requirements are given in Article 3 of the ISO Statutes. ISO was founded on 23 February 1947, and () it has published over 25,000 international standards covering almost all aspects of technology and manufacturing. It has over 800 technical committees (TCs) and subcommittees (SCs) to take care of standards development. The organization develops and publishes international standards in technical and nontechnical fields, including everything from manufactured products and technology to food safety, transport, IT, agriculture, and healthcare. More specialized topics like electrical and electronic engineering are instead handled by the International Electrotechnical Commission.Editors of Encyclopedia Britannica. 3 June 2021.Interna ...
