• And what is calibration anyway? According to one of Infopedia`s definitions, “calibration” is “checking the operation of an instrument to adjust its specifications to a standard.” And that`s exactly what happens when calibrating a balance or other measuring instrument. When we talk about weighing and balancing, especially trade scales, you often hear terms such as metrology, legal metrology, calibration, verification, and standard weight. But it is not always clear what each concept means and what these processes and objects are really for. The measuring instruments are subjected to various tests to ensure compliance with the relevant technical and legal requirements. Once the device is in operation, it is necessary to check it periodically or after©repairs or modifications to verify that it continues to measure correctly and that its errors in measurements are less than the maximum permissible errors. If the device passes the inspection, a “compliant” label is affixed to it, otherwise a red deactivation label for the service is applied. Virtually all countries offer this protection by including metrology in their legislation, hence the term “legal metrology”. The aging of components, temperature changes, mechanical stresses that support equipment©, etc. gradually deteriorate their functions. When this happens, measurements and tests lose confidence and harm both the design and quality of the product± a result. It is the responsibility of the legal metrological control to verify compliance with the applicable national legislation on metrology. This includes checking the correct quantity and content in prepackaged products; verify compliance with national rules. The testing of a measuring instrument is a conformity assessment procedure (with the exception of model assessment) which leads to the affixing of a test mark and/or the issue of a roadworthiness certificate.
This is a series of administrative, visual and technical inspections 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 testing and marking. and the issuance of a technical inspection certificate that verifies and confirms the measuring instrument. Every day, scales are used in various commercial sectors. Which, on the one hand, means that they must be regulated by legal metrology, and on the other hand, they can undergo a lot of wear and tear and require constant maintenance – which is done through calibrations. • So what exactly is legal metrology? Whether it is a visit to the supermarket, butcher shop or in other circumstances, we constantly weigh objects and carry out different types of measurements. Legal metrology, legal metrological control, ensures that the results of these instruments used in our daily lives are correct, of course within a certain margin of error. Legal metrology is the part of metrology that is subject to legal/regulatory control. Legal metrology promotes economic and social benefits. Avoid unjustified payments by consumers for the use of meters that do not comply with legal requirements or prepackaged products that do not contain the correct quantity.
Manufactured with strictly controlled standard weights, calibrations performed by certified companies provide you with a legal guarantee and not only that the scales work with the expected and expected precision. Legal metrology is the part of metrology (measurement science) that refers to activities arising from legal requirements that apply to measurements, units of measurement, measuring instruments and measurement methods carried out by competent bodies. Legal metrology is more than a scientific discipline, but a field of practical application in everyday life. Above all, it serves to protect us as consumers. The idea is to make sure that when we go shopping, we pay exactly what we bring home. In Spain, there are three types of conformity assessment bodies in the field of legal metrology± notified bodies, measurement control bodies and approved metrological testing bodies. Legal metrology is the part of metrology that is subject to legal/regulatory control. Legislation in the field of metrology contains provisions on the inspection of measuring instruments and measuring instruments.
