Ensuring the validity of measurement results through the use of triangulation rules

Measurement results are critical in various industries, including healthcare, aerospace, and manufacturing. Inaccurate measurements can lead to severe consequences, such as faulty medical diagnoses, airplane crashes, and defective products. Therefore, it is essential to ensure the validity of measurement results to maintain the integrity and reliability of measurements. To comply with the ISO/IEC 17025 standard, laboratories must demonstrate the validity of their measurement results [1]. They can achieve this by using the triangulation rules, which involves using multiple methods or instruments to measure the same quantity. By comparing the results of multiple measurements, laboratories can identify any discrepancies.
