What is the significance of OIML classification?

OIML (International Organisation of Legal Metrology) classes (E2, F1, F2) define the maximum permissible error for a weight. E2 offers the highest precision, suitable for calibrating high-accuracy balances, while F1 and F2 are for less stringent applications.

Why is stainless steel a preferred material for calibration weights?

Stainless steel is chosen for its excellent corrosion resistance, durability, and stability over time. It also has low magnetic properties, which is crucial for precision weighing.

Is certification necessary for calibration weights?

For critical applications requiring traceability and compliance with quality standards (e.g., ISO 9001, GLP/GMP), certification like ISO 17025:2017 is essential. For less critical internal checks, a Statement of Accuracy may suffice.

How should calibration weights be stored and handled?

Weights should always be stored in their protective cases to prevent damage and contamination. They should be handled with clean, lint-free gloves to avoid transferring oils or dirt, which can alter their mass.

How often should calibration weights be re-calibrated?

The re-calibration frequency depends on usage, environmental conditions, and regulatory requirements. Typically, weights used in critical applications are re-calibrated annually, but this can vary.
