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

Class F1 denotes a high-precision calibration weight suitable for calibrating analytical balances and precision scales with a readability typically down to 0.01 mg. It offers a tighter tolerance than lower classes.

Why is OIML certification important for calibration weights?

OIML (International Organization of Legal Metrology) certification ensures that the weight meets internationally recognised standards for accuracy, material, and construction. This is crucial for maintaining traceability and compliance in regulated industries.

What maintenance is required for Class F1 weights?

Class F1 weights require careful handling to avoid scratches or contamination. They should be stored in their protective cases when not in use and cleaned only with appropriate, lint-free materials and methods to preserve their accuracy.

Can this weight be used for balances with lower precision?

Yes, a Class F1 weight can be used to calibrate balances with lower precision (e.g., those requiring Class M or F2 weights). However, using a higher class weight than necessary may be an overspecification for some applications.

How often should calibration weights be re-calibrated?

The re-calibration frequency for weights typically depends on their usage, environmental conditions, and internal quality management systems. It is common practice to have them re-calibrated annually or biennially by an accredited laboratory.
