Conclusion
Use of reference materials

The use of reference materials is now a central element in demonstrating the reliability and comparability of measurement results, regardless of the technical field or regulatory context in question. Their role goes far beyond simply meeting a regulatory requirement: they directly contribute to the control of the measurement process and the credibility of decisions based on analytical results.

Changes in the regulatory framework—particularly the 2016 publication of ISO 17034—have helped clarify and harmonize the requirements applicable to reference material producers. This development strengthens confidence in the materials available on the market, while reaffirming a fundamental principle: the suitability of a reference material for a specific application remains the responsibility of the user.
