20 kg Block Weight OIML F1, Polished Stainless Steel, 100 mg Tolerance - KERN

Product information "20 kg Block Weight OIML F1, Polished Stainless Steel, 100 mg Tolerance - KERN"

Combining OIML Class F1 accuracy, a 20 kg nominal mass and a polished stainless steel block design, this test weight supports traceable calibrations and a dependable measurement routine; order the item directly via Metav Werkzeuge or consult our specialists if further technical details are required.

KERN 326-38 Block Test Weight (20 kg, OIML Class F1)

The KERN 326-38 block test weight is a precision 20 kg reference mass designed for calibration and verification of laboratory and industrial scales under OIML Class F1 standards.

  • OIML Class F1 accuracy
  • 20 kg nominal mass
  • Polished stainless steel block
  • Recommended protective case

Consistent accuracy for traceable measurements

The block is manufactured to OIML Class F1, which guarantees a maximum permissible error of 100 mg for the 20 kg nominal mass; this level of precision makes it suitable as a reference mass for routine calibrations and internal quality control. By using a certified reference such as this, measurement uncertainty is reduced and documentation for audits becomes straightforward, supporting reliable process control and fewer rejections in production environments. The result is a measurable improvement in repeatability and confidence in weighing results.

Robust finish for long service life and easy handling

Built from polished stainless steel, the block form offers corrosion resistance and a hygienic surface that is easy to clean after use on the workshop floor or in the lab. The design combines a compact block shape with a handling form adapted for secure lifting and placement; this minimises handling time and risk of damage. The KERN construction and the stainless finish contribute to long-term dimensional stability, so the mass remains a dependable reference between calibrations.

Compliance guidance and calibration options for assured validity

EG initial verification for test weights will no longer be possible after 30.11.2025; for continued traceability, a DAkkS calibration is recommended and is equivalent for most professional applications. The product is suitable as a single reference weight for scale verification and can be integrated into in-house calibration procedures to maintain conformity with internal and external standards. For transport and storage, a protective case is advised because of the high accuracy class, ensuring the mass keeps its calibrated state over time.

FAQ

What level of accuracy does this test weight provide?
The KERN 326-38 block test weight is certified to OIML Class F1, which corresponds to a tolerance of 100 mg for the 20 kg nominal mass and is suitable for routine calibration and quality control.

Can this weight be used for both laboratory and industrial scales?
Yes, the 20 kg block test weight is intended for calibration and verification of laboratory and industrial scales where an OIML Class F1 reference is required.

Is a protective case necessary for this test weight?
A protective case is recommended for the KERN 326-38 because the high accuracy class makes the mass sensitive to contamination and mechanical damage during transport or storage.

What calibration is advisable given the change to EG initial verification?
Since EG initial verification for test weights is no longer possible from 30.11.2025, a DAkkS calibration is recommended for equivalence in traceability and documentation.

Who manufactures the weight and where is it from?
The weight is manufactured by KERN and the origin is indicated as Germany.

20kg Aluminium-Protected Case For Block Test Weights, Padded, Class F1–M3 - KERN
20kg Aluminium-Protected Case For Block Test Weights, Padded, Class F1–M3 - KERN

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.
