How should calibration standards be stored?

Storing calibration standards in a cool, dry place with proper labeling and expiry information protects their stability and traceability. Temperature and humidity can affect the physical state or composition of standards, leading to drift in measurements. Proper labeling, including lot numbers and expiry dates, ensures you can trace results to a specific batch and know when a standard should be retired. Keeping them free from contamination and cross-contact is essential so residues from other materials don’t alter the standard’s properties or introduce errors. This combination—stable storage conditions plus complete, legible labeling—maintains accuracy and auditability of the calibration process.
