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

Class F1 indicates a high-precision weight suitable for calibrating analytical balances and top-loading balances with readabilities typically ranging from 0.01 mg to 0.001 g. It offers a tighter tolerance than lower classes.

Why is the material important for calibration weights?

The material, commonly stainless steel, is crucial for its density, magnetic properties, and corrosion resistance. These factors ensure the weight's stability and accuracy over time, minimising environmental impact.

What is OIML certification?

OIML (International Organization of Legal Metrology) certification ensures that the weight meets international standards for accuracy and quality. This is important for traceability and compliance in regulated industries.

How should calibration weights be handled and stored?

Calibration weights should be handled with clean, lint-free gloves or forceps to avoid transferring oils or dirt. They should be stored in their protective cases in a stable, clean environment to prevent damage or contamination.

Can this weight be used for balances with different readabilities?

While an F1 class weight is designed for high-precision balances, it can be used for balances with lower readabilities. However, using a higher class than necessary may be an over-specification for some applications.
