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

Class F1 denotes a high-accuracy class of calibration weight, primarily used for calibrating or verifying Class F2 weights and for use with high-accuracy weighing instruments (Special Accuracy Class I and High Accuracy Class II).

Why is the material 'High-grade Stainless Steel' important for this type of weight?

High-grade stainless steel (such as NC-001-0.2K-F1-SS mentioned) is crucial for its stability, corrosion resistance, low magnetic permeability, and hardness, which all contribute to maintaining the weight's accuracy over time and use.

What is OIML R 111-1?

OIML R 111-1 is an international recommendation from the Organisation Internationale de Métrologie Légale (OIML) that specifies the metrological and technical requirements for weights of accuracy classes E1 to M3, including material, surface finish, density, and maximum permissible errors.

How often should Class F1 weights be recalibrated?

The recalibration frequency depends on usage, environmental conditions, and internal quality procedures. Typically, F1 weights used in critical applications are recalibrated annually, but this can vary.

Can this 100g F1 weight be used to calibrate a standard laboratory balance?

Yes, a Class F1 100g weight is suitable for calibrating or verifying standard laboratory balances, especially those requiring high precision, to ensure their accuracy and traceability.

Density: Commonly around 7,950 kg/m³ for stainless steel F1 weights, as per OIML standards.
Tolerance Limit: For this class, tolerances are typically very tight, in the order of ±0.05 mg for a 100g weight, as defined by OIML R 111-1.
Surface Finish: Polished or satin finish to minimise contamination and wear.
Packaging: Individual weights are commonly supplied in a protective wooden or plastic case to prevent damage and maintain cleanliness.

Class F1 denotes a high-accuracy class of calibration weight, primarily used for calibrating or verifying Class F2 weights and for use with high-accuracy weighing instruments (Special Accuracy Class I and High Accuracy Class II).

Calibration weights and kits are essential for maintaining measurement accuracy across laboratories, biotech and pharmaceutical facilities. Buyers typically prioritise certified traceability, material quality and condition of surface finish when purchasing used sets. Industry sentiment favours equipment from established manufacturers with documented calibration history. Common strengths include durability and long operational lifespan when properly stored. When buying used, verify calibration certificates, inspect for corrosion or damage, and confirm all weights in the set are present and accounted for.
