Calibration Methodology
& Traceability

ISO 16063, ISO 9612, ISO 1996, GUM, and guidelines equivalent to ISO/IEC 17025.

Although I am not ISO/IEC 17025 accredited, all measurements and calibrations are conducted using ISO-compliant methodologies. This includes thorough uncertainty evaluation, repeatability and reproducibility assessments, and adherence to the principles outlined in ISO 16063 and ISO Guide 98-3 (GUM).

Evaluation of measurement uncertainty with full traceability assurance for all instruments used.

Each test includes a clearly documented uncertainty budget, traceability to calibrated reference equipment, and a structured report detailing procedures, measurement chain comparison, and full analysis of results. This approach ensures technical transparency, suitable for internal QA, verification processes, or interlaboratory comparisons.
