It is the responsibility of the legal metrological control to verify compliance with the applicable national legislation in metrology. This includes checking the correct quantity and content in prepackaged products; to verify compliance with national regulations. It is very important to note that legal metrology affects not only the health sector, but also trade, the daily purchase of goods by weight, the purchase of fuel and the provision of public services in the residential area. Virtually all countries offer this protection by including metrology in their legislation, hence the term “legal metrology”. With regard to metrological verification requirements, in order to protect the public interest in measuring instruments, the Government, in particular the Ministry of Industry and Trade, must publish a set of standards defining the technical and administrative requirements for measuring instruments subject to legal metrology. Legal metrology protects public safety, the environment, consumers and traders and is fundamental to fair trade. The State organizes the infrastructure of legal metrology through which the following objectives are achieved Legal metrology is the part of metrology that is subject to legal/regulatory control. The testing of a measuring instrument is a conformity assessment procedure (with the exception of model evaluation) leading to the affixing of a test mark and/or the issue of a test certificate. It is a series of administrative, visual and technical tests aimed at verifying and confirming that a measuring instrument complies with legal requirements through conformity assessment procedures (with the exception of model evaluation) which include tests and markings.
and the issuance of a test certificate that verifies and confirms the measuring instrument. Legal metrology is the part of metrology (science of measurements) that refers to activities resulting from legal requirements that apply to measurements, units of measurement, measuring instruments and measurement methods performed by competent bodies. Measuring instruments are subjected to various tests to ensure compliance with relevant technical and legal requirements. We use time to arrive on time and satellite positioning systems to determine our location. Scientific Metrology: Deals with the technical and experimental problems of measurement, including: the experimental realization of units of measurement and the preservation and maintenance of models, as well as the research and development of new measurement techniques. The metrology program includes the determination of the necessary measuring instruments, measuring ranges and tolerances directly related to the production processes, as well as the tests and tests carried out by them in accordance with the quality control procedure of the manufactured products. During the commemoration of the International Day of Metrology, the Deputy Superintendent for the Control and Revision of Technical Regulations and Legal Metrology of the Supervision of Industry and Commerce, Jairo Enrique Malaver, explained the scope of “legal metrology” in Colombian society. Companies are responsible for implementing measurement programs in such a way as to ensure the reliability of the measurements and their results within the required accuracy range. Measuring instruments subject to metrological control in the Metrology Laboratory of Costa Rica. These are: breathalyzers, kinemometers, blood pressure monitors, tanker trucks. Metrology is defined as the science of measurements. We also rely on the results of the measurements to confirm that the water we drink or the air we breathe is free of contaminants.
Measurements are such an important part of our daily lives that we often take them for granted and may not even notice them. In order to achieve these objectives, it is necessary to have a technical basis for evidence and judicial proceedings by impartial, competent and relevant bodies. Metrology according to its field of application is classified into: legal metrology, industrial metrology and scientific metrology. “Measurements and gauges have always been present in product exchange scenarios; The fundamental concern is that the measurements and their results are reliable,” he said. In the field of weighing, legal metrology is the approval of devices, which indicates that this equipment is approved for commercial transactions, that is, for the sale of heavy products with this equipment. Legislation on measurement and measure is necessary in all these cases, as well as when it is necessary to protect both the buyer and the seller in commercial transactions, or when the measures are used to enforce sanctions. They are used to monitor and control processes, to determine the conformity of products with their functionality, quality and suitability and are present in the assessment of the conformity of products to standards and / or technical regulations. It can also be defined as the art of measuring “good”. Metrological monitoring focuses on the analysis of the net content of a prepackaged product and on guidelines for the control and monitoring of metrological verification units. Another example of the importance of measurement is that incorrect doses of radiation in cancer treatment can be crucial to our health.
The concepts of metrological verification, calibration and traceability are very important to understand how confidence in the meter is ensured and thus provide the security required by the consumer. Measuring means counting, comparing one unit to another, giving a numerical evaluation, assigning a value to the properties and properties of objects, substances or physical phenomena called physical quantities such as length, volume, temperature, etc. Ensure sufficient accuracy in business operations. Facilitate domestic and international trade. Fraud prevention. Although it is not very well known, it is in daily contact with us, from ordinary activities that we do not pay attention to, such as a recreational trip, to those of great importance that can affect life, health and the environment; For example, in the measurement of blood pressure, body temperature, laboratory tests, drug manufacturing and even in the quantification of pollutants produced by industry. Very often, small errors in both directions are averaged in a large number of measurements. However, biased errors can lead to significant financial losses. We consume electricity, gas and water, which are charged according to the results of the measurements, we buy meat, fish, fruits and vegetables by weight, we refuel our cars in volume, we check our cars to check our exhaust emissions, etc.
