Software & Data
In modern metrology and calibration, hardware instruments represent only one half of the measurement system. The software used to control these instruments, acquire data, process results, and generate certificates is equally critical. Ensuring that this software performs precisely as intended and that the resulting data remains secure, traceable, and unaltered is paramount.
The disciplines of Software Validation and Data Integrity form the bedrock of trust in digitized measurement processes. Without rigorous controls in these areas, even the most accurate physical standards and instruments can produce invalid, unreliable, or non-compliant results.
The Digital Metrology Environment
A contemporary calibration laboratory relies on a complex ecosystem of software applications, including Laboratory Information Management Systems (LIMS), automated calibration scripts (e.g., Fluke MET/CAL, Keysight VEE), spreadsheet calculators, and embedded instrument firmware. Each of these components must be evaluated for its potential impact on measurement quality.
Regulatory Imperatives
International standards strictly mandate the control of software and data.
- ISO/IEC 17025:2017: Section 7.11 explicitly requires that laboratory information management systems used for the collection, processing, recording, reporting, storage or retrieval of data be validated for functionality prior to introduction. It also mandates protection against tampering and unauthorized access.
- FDA 21 CFR Part 11: For laboratories operating in or supporting regulated pharmaceutical and medical device sectors, electronic records and electronic signatures must be trustworthy, reliable, and equivalent to paper records, necessitating stringent audit trails and access controls.
