Ensure weighing accuracy with certified calibration weights
Calibration weights are precision mass artefacts used to verify, adjust and document scale performance, providing process security and repeatable results in production, quality assurance and laboratories. They come in defined nominal values and accuracy classes such as E1, F1 and M1, so you can match the right weight to the scale’s readability and application to avoid false confidence or unnecessary cost. Correct handling—using gloves or tweezers, storing weights in their case and avoiding contamination—keeps them reliable, while routine checks at multiple points in the weighing range reveal issues caused by vibration or temperature changes.

KERN 362-96 weight set, OIML Class M3, 1 g–1 kg The KERN 362-96 is a precision OIML Class M3 weight set designed for calibration and verification tasks in workshops and laboratories. OIML Class M3 accuracy Nominal range 1 g–1 kg Stainless steel and lacquered cast iron Button and cylinder forms Supplied in a wooden storage block Reliable calibration for routine verification The set is specified to OIML Class M3, which means it is intended for routine calibration and verification where moderate precision is required. This classification provides a clear, comparable standard for conformity testing and periodic checks on balances and scales. Using certified weights of 1 g–1 kg reduces uncertainty in day-to-day measurements and supports consistent quality control. The inclusion of both fine and coarse nominal values ensures that a wide range of instruments can be checked without the need for multiple separate sets, improving operational efficiency in production and maintenance environments. Materials and shapes explained for consistent results Small masses in the set are made from stainless steel, providing corrosion resistance and long-term surface stability; larger masses are formed from lacquered cast iron to combine robustness with economical mass production. The mixture of button form pieces (used for the smallest and the largest items) and cylinder form pieces (notably for 100 g and 200 g) is chosen to aid handling and reduce surface contact during weighing. These design choices translate into practical benefits: easier manoeuvring during calibration, reduced risk of contamination, and a stable mass distribution that supports repeatable readings over many cycles. Secure storage, handling and application benefits The weights are supplied in a fitted wooden block, which protects surfaces and keeps the set organised for quick access during verification routines. Proper handling—using tweezers or gloves and keeping the set in a stable, dust-free environment—helps preserve the nominal values and extends service life. With a total set weight of approximately 2.8 kg, the block remains portable while offering a complete kit for on-site checks. Manufactured in Germany, the set is suitable for workshop and laboratory verification tasks where M3 tolerances are acceptable and cost-effective, routine calibration is required.

The KERN 362-96 complies with OIML Class M3, making it suitable for routine calibration and verification where M3 tolerances are appropriate. Which materials are used for the individual weights? The set combines stainless steel for the smaller masses (1 g–50 g) and lacquered cast iron for the larger masses (from 100 g), as specified for this KERN set. Why are there both button and cylinder shapes in the set? Button form pieces reduce surface contact and are easier to handle for very small and certain large masses; cylinder shapes (100 g, 200 g) improve centring on balances and assist repeatable placement. How should the weights be stored and handled to maintain accuracy? Store the weights in the supplied wooden block, avoid direct skin contact with mass surfaces, and keep them in a dry, temperature-stable environment to preserve nominal values. KERN — Germany

Ensure measurement reliability with certified test weights
Test weights are defined mass artefacts used to verify, adjust and document the performance of scales across production, laboratory and quality assurance environments. They provide the objective reference needed to confirm accuracy, repeatability and process reliability where documented results matter.
How test weights work and where they matter
Test weights serve as traceable references with fixed nominal values — for example 1 g, 100 g, 1 kg or 20 kg — and are manufactured to specific accuracy classes so that permitted deviations are known and comparable. In practice they are used to check a scale’s reading at one or several points within its range, to distinguish between calibration (checking and documenting deviation) and adjustment (setting the scale to read correctly). Typical situations include routine production checks, audit-prepared quality control, laboratory validation and fault-finding when instability, vibration or environmental factors affect readings.
Immediate performance gains for production and quality assurance
- increase measurement confidence by using weights matched to the application and scale resolution
- reduce downtime and troubleshooting time through systematic multi-point checks (lower, mid, upper range)
- protect process validity by choosing the correct accuracy class: E1, E2, F1, F2, M1, M2, M3
- limit handling-related error: use tweezers for small weights and clean gloves for larger items
- extend usable lifetime through disciplined storage in protective cases and regular control or recalibration

FAQ
What exactly are test weights?
Test weights are defined mass artefacts with fixed nominal values that are used to check, adjust or document scale performance within quality assurance and calibration workflows.
Which accuracy classes are available and when should I use them?
Accuracy classes range from E1/E2 for the highest demands, through F1/F2 for precise everyday applications, to M1–M3 for robust industrial or platform scales. Select the class that matches the required measurement uncertainty and the operating environment.
How often should I check my scale with test weights?
Frequency depends on the criticality of the process: critical operations often require daily or per-shift checks, while less critical applications may use weekly or monthly intervals; always check after location changes or suspect readings.
Why must test weights not be touched with bare hands?
Skin oils and moisture alter surface mass and can introduce measurable errors, especially for small nominal values. Use tweezers or clean gloves to maintain traceability and reliability.
What is the practical difference between calibration and adjustment when using test weights?
Calibration documents how far a scale deviates from the nominal value; adjustment actively corrects the scale to bring it back into tolerance. Both processes make use of test weights but serve different quality objectives.
Metav and KERN & Sohn provide the products, documentation and calibration pathways to integrate test weights into routine quality assurance — ensuring your measurements remain verifiable, repeatable and audit-ready.
