What does 'Class F1' signify for a calibration weight?

Class F1 indicates a high-precision weight, suitable for calibrating analytical balances with a readability down to 0.01 mg, and for use as a reference standard in laboratories.

Is a calibration certificate essential for a used weight?

While not always legally mandated for purchase, a current calibration certificate is highly recommended for any weight used in accredited or critical measurement applications to ensure traceability and accuracy.

How should a Class F1 weight be handled and stored?

These weights should be handled with tweezers or gloves to prevent contamination and stored in their protective case in a stable environment to avoid damage or changes to their mass.

Can this 5g weight be used to calibrate any balance?

It is suitable for calibrating balances where a 5g reference point is required and where the balance's readability aligns with the F1 class precision. Always consult your balance's manual for specific calibration weight requirements.

What is the significance of the material and density?

High-grade steel minimises corrosion and magnetic properties. The specified density is critical for calculating air buoyancy corrections, ensuring accurate mass determination in varying atmospheric conditions.
