Publications in subseries SP 2200 provide information on the status and evolution of U.S. and international legal metrology documentation standards; the use, facilitation and best practices in sustainable investment; and technical guidance and training according to OWM. In general, these legal metrology standards and services describe the regulatory practices of measurements and measuring instruments to achieve consistent application in the distribution of commercial products and services. Publications in this subseries also provide additional technical information not included in the NIST Manual Series. Legal metrology is the science of measurement. EU legislation on legal metrology is one of the pillars of the internal market for goods. EU requirements aim to promote innovation, public safety, environmental protection and fair trade. Measuring instruments harmonised by EU legislation range from scales, tape measures, petrol pumps and consumption meters (gas, electricity, thermal energy, water) to taximeters and weighbridges. EU law sets out the essential requirements that measuring instruments must meet in order to be sold or put into service in the EU. The aim is to ensure the accuracy of the measures and to promote transparency and fairness in trade. The European System of Units dates back to the International System of Units (SI). The SI serves as a global standard, and EU law makes SI units the legal units used to indicate quantities in the EU. Approval of the metrological and technical characteristics and qualities of the physical representation of weight or dimensions with prescribed tolerance.

According to the Ministry of Consumer Affairs, compliance with the Legal Metrology Act of 2009 by stakeholders ensures the accuracy and accuracy of the measurement, which plays a very important role in everyday life. Transparent and efficient legal metrology creates trust in trade, industry and consumers and creates a harmonious environment for doing business. Yes, the test is mandatory for all weights and dimensions. The rules make this possible by mandating the testing of all measuring and weighing instruments in accredited laboratories approved by the Government of India and certified by NABL. This report provides a summary of amendments to NIST Handbooks 44 (2022), 130 (2022), and 133 (2020) and includes an archival record of proposals, related actions, and recommended amendments reviewed and adopted by NCWM members for the purpose of assisting the weights and measures community in consistent interpretation and implementation of NIST manuals and other related documents. Also included is a high-level summary of technical aspects in the form of a detailed analysis of the OWG, including background information, reports from regional associations and recommendations on issues to be considered or adopted in the NCWM for 2022.
Nearly 50% of U.S. gross domestic product is affected by the sale of products and services based on weights or measures. Industry sectors likely to be affected by regulatory measurement standards include food retail, petroleum products, transportation and chemicals, including sectors in emerging commercial markets such as electric vehicle charging and e-commerce. OWM programs aim to ensure that consumers get value for money and that sellers receive fair payment for the goods and services they sell based on weight or measure through a unified metering infrastructure. This, in turn, promotes consumer confidence and helps ensure fair competition, ranging from local business to global trade. In practice, OWM works with state and local weights and measures, federal agencies, industry and consumer groups, and national and international standards organizations (SDGs) to design, develop, promote and deliver the following standards and services: As the National Metrology Institute for the United States, NIST, through the Office of Weights and Measures (OWM), Provides documentary standards and services for legal metrology – the practice and process of applying regulatory structure and enforcement to metrology. OWM`s mission is to ensure national consistency in legal metrology and to provide standards and services to achieve fairness in the commercial marketplace. This is directly related to NIST`s mission to promote U.S. industrial competitiveness and improve economic security. Originally founded in 1836 as the Standard Weights and Measures Construction Bureau, OWM also remains the oldest office in NIST. For more information, see A Brief History of OWM. The Law on Legal Metrology provides for various rules from time to time.
One of the most important rules relating to the manufacture, import, repair of weights and dimensions or model approval is the Legal Metrology (MODEL APPROVAL) Regulations 2011. The Department of Legal Metrology: The nomenclature of the Department of Weights and Measures is replaced by “The Department of Legal Metrology”, as notified by the Government upon publication of the notification. As the name suggests, the Department of Legal Metrology refers to units of measurement and weight, measurement methods and measuring instruments, as well as regulatory protections for the public. The Department of Legal Metrology is one of the most important bodies of consumer protection. It plays an important role in the user-friendly management of services to citizens. It deals with technical and legal requirements to protect the public interest from the point of view of safety and accuracy of weights, dimensions, etc. Type certification under the Legal Metrology Act 2009 means that all weight and measuring instruments test and calibrate in accordance with the standards set out in the Statutory Metrology Act and maintain accuracy. EU legislation on pre-packaging defines the quantity contained in pre-packaged products. It guarantees the net quantity in pre-packages and the volume of products in bottles or jars.
EU law requires national authorities to carry out regular market surveillance. EU law prohibits EU countries from legislating on sizes and sets sizes for wines and spirits. In collaboration with the NIST Research Library, the Office of Weights and Measures (OWM) has launched a new subseries of NIST special publications, SP 2200: Legal Metrology. The instruments that fall under the provisions of the Verification and Calibration Act are: The National Conference on Weights and Measures (NCWM), in partnership and collaboration with the NIST Office of Weights and Measures (OWM) and the Weights and Measures Divisions of some U.S. states, launched the 2022 National Survey of 20 Lb LPG (Propane) Cylinders, which represents the current market practice of manufacturing, filling, selling and replacing 20 lb LPG cylinders. These rules govern the granting of authorization by the central government for the manufacture of mass and measurement instruments in order to regulate the approved and uniform use of these instruments in the market, thus avoiding the use of defective and unapproved equipment. These rules allow the desired laboratories to apply for recognition of the performance of certain tests for the approval of the model of a measuring apparatus. NIST Summary of Legal Metrology Activities in the United States (NIST SP2200-2) NKG team members accompany the customer through the entire process, from document creation to product testing and submission of the test report to headquarters for approval. Under the aegis of the Department of Public Consumption, Food and Distribution, the Directorate of Legal Metrology is constituted as a separate wing in India. Rules, compliances and standards are enforced under the law and rules of legal metrology through the headquarters in New Delhi, from where they are delegated to the respective states to ensure effective and continuous compliance with laws and rules. For detailed information on OSO program activities and staff expertise, see Programs.
For testing in an approved laboratory, at least 2 samples are required, and the cost of testing is as follows: Stay tuned for the following NIST special publications coming out this fall: 2022 NCWM-NIST National Survey of 20 Lb LPG (Propane) Cylinders (NIST SP2200-1) According to the 2011 Legal Metrology Model Approval Rules, The most important aspect is to understand what a model is and what the model approval process is.
