The phrase identifies a process that integrates the requirements of a specific international standard, a method for evaluating measurement variability, and a common software tool. It represents the practice of determining the range of values within which the true value of a measurement is likely to lie, performed in accordance with ISO 17025 standards and implemented using spreadsheet software.
The process is critical for laboratories seeking accreditation under ISO 17025, demonstrating the competence to produce reliable and accurate test and calibration results. Historically, calculating measurement variability involved manual methods prone to error and time-consuming. The use of spreadsheet software automates this, enhancing efficiency and reducing the risk of miscalculation, contributing to improved data integrity.
