ISO 14111:1997

Overview

ISO 14111:1997 - "Natural gas - Guidelines to traceability in analysis" provides guidance on implementing metrological traceability in natural‑gas analysis. Rather than prescribing specific calibration protocols, it clarifies fundamental concepts (traceability chains, reference materials, uncertainty and accuracy) and offers practical advice for designing traceability strategies using reference gas mixtures. The standard is intended to support the development of specific traceability provisions in other natural‑gas analytical standards.
