ISOGUMjärjestelmän

The ISOGUMjärjestelmän (ISO‑GUM system) is a web‑based platform developed by the Finnish Metrology Institute to support the implementation of the Guide to the Expression of Uncertainty in Measurement (GUM). It provides laboratories, industry partners and academic researchers with a unified workflow for creating, analysing and reporting measurement uncertainty budgets. The system incorporates statistical analysis tools for processing measurement data, supports metadata management for traceability, and allows integration with existing instrumentation and data acquisition software.

Key features of the system include a user‑friendly interface for entering measurement parameters, automated propagation of uncertainty, and real‑time generation of detailed uncertainty reports in multiple formats. An extensive library of reference values and calculation templates is available, enabling rapid setup of budgets for common measurement tasks. Collaboration functions allow multiple users to review and edit uncertainty calculations, while audit logs track changes to ensure compliance with ISO/IEC 17025 accreditation requirements.

ISOGUMjärjestelmän also offers educational resources such as tutorials, webinars and sample case studies, which serve both new users and experienced metrologists. By standardising uncertainty calculation procedures and providing traceability records, the system enhances confidence in measurement results across the Finnish scientific and industrial community. The platform continues to evolve through user‑feedback‑driven updates, maintaining alignment with updates to the GUM guidance and related international standards.
