Métrologique

Métrologique is a French term that translates to "metrological" in English. It refers to the science of measurement. This field encompasses all theoretical and practical aspects of measurement, irrespective of the measurement uncertainty and the field of application. Metrology includes the study of units of measurement, standards, instruments, and methods. It is fundamental to science, engineering, industry, and commerce, ensuring accuracy, reliability, and comparability of measurements.

The discipline of metrology is divided into three main branches. First, scientific metrology deals with the establishment of measurement units and systems, the development of new measurement methods, and the study of measurement uncertainties. Second, industrial metrology focuses on the practical application of measurement science in manufacturing and industry, ensuring that products meet specified standards and quality requirements. This includes calibration and verification of measuring instruments used in production. Third, legal metrology is concerned with measurements that have legal implications, such as those used in trade, public safety, and environmental protection. It involves regulating the accuracy and use of measuring instruments to protect consumers and ensure fair trade.

The goal of metrology is to ensure that measurements are accurate, consistent, and traceable to internationally recognized standards. This is crucial for scientific research, technological advancement, and global trade. Without metrology, it would be impossible to compare results from different laboratories, ensure the safety of products, or conduct international commerce with confidence.
