Block calibration weight by KERN — 20 kg, OIML Class M1, coated cast iron
The Block calibration weight is a compact calibration reference intended for routine verification and adjustment of industrial and laboratory scales, providing a stable mass reference in workshop and quality-control environments.
- OIML Class M1 certified
- Nominal mass: 20 kg
- Coated cast iron block design
Precise conformity for everyday calibration needs
This block serves as a stable reference mass that meets OIML Class M1 requirements, offering a defined tolerance of 1 g. The standardised accuracy class simplifies traceability in routine checks and documentation, reducing uncertainty when comparing a balance's readout with a known mass. By using a certified reference, calibration intervals can be planned more effectively and internal quality procedures become easier to justify during audits.
Robust construction that supports long-term reliability
Manufactured as a coated cast iron block, the design emphasises mechanical stability and longevity. The compact geometry minimises handling errors and contact points that could alter apparent mass, while the protective coating resists surface corrosion in typical workshop environments. This combination reduces the need for frequent replacement and helps maintain consistent performance during regular verification cycles.
Practical handling and storage for safe use
The block form factor simplifies placement on platforms and inside weighing pans, supporting efficient calibration workflows. When used with suitable lifting or handling aids, the solid construction keeps centre of mass predictable and stable during transfers. Routine care — gentle cleaning and dry storage — preserves the coating and the defined surface condition that underpins repeatable measurements, helping to keep maintenance time and process interruptions to a minimum.
Documentation and integration into quality systems
The product's defined nominal mass and documented tolerance allow straightforward inclusion in calibration logs and ISO-style quality records. For traceability, the weight can be referenced by its SKU and GTIN within asset registers, streamlining inventory control and compliance reporting. Choosing a standardised reference mass simplifies comparisons between different balances across workshops and production lines.

FAQ
What accuracy class does this weight conform to?
The weight conforms to OIML Class M1, which is specified with a tolerance of 1 g for the 20 kg nominal mass and is suitable for routine calibration and verification tasks.
Is the 20 kg block suitable for workshop scales and laboratory balances?
Yes. The 20 kg block is designed as a calibration reference for industrial and laboratory scales; selection should follow the instrument manufacturer's recommended test masses and the intended verification tolerance.
How should the calibration weight be stored to preserve its accuracy?
Store the weight in a dry, dust‑free environment and avoid aggressive cleaning agents; the coated cast iron surface benefits from gentle care to maintain the surface condition that supports repeatable measurements.
Does the product come with a certification document?
The item is supplied as an individual calibration weight in OIML Class M1; for audit or calibration records, reference the SKU 346-88 and GTIN 4045761241657 when recording the component in quality documentation.
Can this block be used for field checks or only in a controlled lab?
The block's robust coated cast iron construction suits routine field checks and controlled laboratory use; however, environmental conditions and handling practices should be considered to maintain the declared tolerance.

Zubehör
Take advantage of a robust combination of lightweight aluminium protection, a padded interior and certified suitability for calibration classes F1–M3 to keep block weights safe in transit and storage. Order the case directly via Metav Werkzeuge or consult the Metav team for specification support. KERN 346-080-600 Aluminium-protected case for block weights, padded The Aluminium-protected case 346-080-600 is a padded transport and storage solution designed for block calibration weights used in laboratory and industrial environments. Aluminium protection housing Padded interior for secure storage Designed for block weights up to 20 kg Suitable for weight classes F1–M3 Robust protection that preserves calibration integrity This lightweight aluminium housing combines structural rigidity with reduced mass, creating a reliable shell for sensitive calibration artefacts. The internal padding secures each block against shocks and vibrations, lowering the risk of dents or surface damage that could alter mass distribution and affect accuracy. For metrology departments and service technicians, a well-protected weight reduces the frequency of re-calibration and associated downtime. The transport case is engineered to match the handling patterns typical for laboratories and mobile calibration services, translating to measurable savings in time and maintenance costs. Designed for calibration workflows and secure handling The case is tailored for block weights, offering precise cut-outs and cushioned support to prevent movement during handling and transit. By ensuring that each weight remains immobile, the case helps maintain the declared tolerance class throughout storage and transport. Compatibility with F1–M3 tolerance classes indicates suitability for a broad range of calibration tasks, from precision laboratories to routine verification in production environments. The combination of a corrosion-resistant outer shell and internal padding also simplifies logistic processes: weights can be moved between sites without additional packaging and with preserved traceability. Practical meaning of classes and how they benefit operations Tolerance classes such as F1 and M3 specify permissible deviation ranges and are widely used in traceable mass measurement. Choosing a dedicated storage solution for weights intended for these classes safeguards the nominal value against mechanical or environmental damage that could invalidate the calibration status. For teams responsible for quality assurance, using a purpose-built protective case reduces the risk of non-conformances during audits and supports consistent measurement results. The case also supports efficient organisation in the workshop or lab, keeping block weights accessible, identifiable and ready for use.
