Some authors define it as the application of the principles and methods of scientific metrology to the specific needs and requirements of the industry. This involves the development and implementation of systems of proper measurement and calibrationas well as the evaluation and control of the uncertainty of the measurements made.
Other authors highlight the importance of industrial metrology in ensuring the quality of manufactured products, due to the fact that it provides the foundations to maintain the measurement standardsand thus carry out tests and tests that allow verifying compliance with the technical requirements and product specifications.
In this way, industrial metrology deals with measurements in the manufacturing field, ensuring precision, reliability and the traceability of each pieceas well as the contribution to the quality of the products.
What is the goal of industrial metrology?
The main objective is to guarantee the accuracy and credibility of measurements in the industrial field. To achieve this, industrial metrology has the following specific objectives:
- takes care of develop and maintain measurement standards used in the industry. Through these standards a traceable reference base is provided for measurements and ensures consistency of results.
- It also focuses on the development and implementation of techniques and measurement methods that allow obtaining accurate results, which implies the use of suitable instruments, which are regularly calibrated and where rigorous measurement procedures are applied.
- On the other hand, he cares about evaluate and control the uncertainty associated with the measurements. Uncertainty is a measure of the reliability of the results and must be taken into account to ensure that measurements are highly accurate for industrial purposes.
- In addition, it plays a key role in the quality assurance of manufactured items. Through tests and trials, compliance with technical requirements and product specifications is verified, guaranteeing their quality and reliability.
What are the characteristics of industrial metrology?
Industrial metrology is based on the quality that is part of the manufacturing process of the parts. The companies have a deficiency in the metrology plan, being between 60% to 80% of failures, despite this, a series of characteristics can be established that distinguish it in the industrial field and that are necessary so that failures do not occur. Some of these are:
- traceability: refers to measurements that are made unambiguously with the benchmarks established nationally or internationally. In addition, a chain is established that guarantees the reliability and comparability of the results.
- Precision: seeks reduce systematic and random errors associated with the measurements. This is achieved by using accurate instruments, as well as proper methods and regular calibration of measuring equipment.
- Uncertainty: industrial metrology takes into account evaluation and control of measurement uncertainty, which recognizes that every measurement has an associated concern, and seeks to assess and communicate appropriately, which allows understanding of the reliability of measurement results.
- Calibration: Emphasis is placed on the calibration of the equipment, since it is the process of comparing the measurements of an instrument with a reference standard and adjust it if necessary. In addition, it ensures that tools are kept in top condition and provide accurate and reliable measurements.
- Standards development: is involved in the progress and maintenance of graduation standardssince they generate a traceable reference base to carry out measurements in the industry, ensuring the consistency and comparability of the results.
