ECO Block weight — KERN calibration mass, OIML Class M1, 5 kg painted cast iron
The ECO Block weight is a compact calibration mass intended for routine accuracy checks of scales and balances in workshops and service environments, combining standard-compliant tolerance with a rugged block design.
- Single calibration weight, OIML Class M1
- Nominal mass 5 kg for medium-accuracy checks
- Painted cast iron block construction
- Compact block design for stable placement
Consistent accuracy for routine calibration
The block is specified to OIML Class M1, which defines permissible deviations for working calibration weights; for this nominal mass the tolerance 250 mg is stated, providing predictable error limits for everyday verification tasks. This classification means the mass is suitable as a calibration mass for many industrial and workshop applications where medium-level accuracy is required, offering a reliable reference during routine checks of shop-floor balances and postal or counting scales. Explaining the standard helps translate technical limits into operational expectations, so maintenance cycles and comparative checks can be planned with clarity.
Robust construction that eases daily handling
Manufactured as a painted cast iron block, the design focuses on mechanical stability and straightforward placement on weighing pans. The block form reduces tip-over risk and concentrates mass in a compact footprint, which benefits fast checks and repeatable handling. The finish provides basic surface protection and aids cleaning after use; combined with the solid construction, this reduces the frequency of handling-related maintenance without compromising the integrity required for routine verification tasks.
Practical application and safe storage in the workshop
Designed as a single test weight, the mass is best integrated into regular calibration routines where traceable high-end certification is not mandatory. For best results, keep the item dry, avoid mechanical shocks and place it on a non-abrasive surface or rest when not in use to preserve the calibration state. For installations that need documented traceability or calibration certificates, planning an external certification step is recommended; technical teams can advise on frequency and methods to match in-house quality assurance regimes while ensuring compliance with local or industry-specific requirements.

FAQ
What does OIML Class M1 mean for daily use?
OIML Class M1 defines the maximum permissible error for a working weight; the ECO Block weight meets that class so it can be used for routine verification where 250 mg tolerance at 5 kg is acceptable.
Is this mass suitable for laboratory reference standards?
The ECO Block weight is specified for medium-accuracy checks; for primary laboratory standards, higher OIML classes or certified reference masses are normally required.
How should the weight be stored to maintain condition?
Store the block on a stable, dry surface and avoid impacts; the painted cast iron finish helps protection, but careful handling will prolong usability.
Can this weight be used on all types of scales?
The mass is intended for use with scales and balances compatible with a 5 kg test weight and appropriate loading; confirm compatibility with the instrument’s loading area before use.
Is a calibration certificate included with the product?
A calibration certificate is not specified in the product data; if certification is required, arrange traceable calibration through an accredited laboratory or ask Metav Werkzeuge for available options.

Benefit from an aluminium-protected housing, a padded interior and compatibility with block weights up to 5 kg and calibration classes F1–M3 for safe storage and transport; Order the aluminium-protected case directly via Metav Werkzeuge or ask our consultants if needed. Aluminium-protected case KERN 346-060-600 — Protective case for 5 kg block weights, padded The Aluminium-protected case serves as a purpose-built transport and storage solution for single block weights, combining a robust outer shell with soft interior support to preserve calibration and dimensional integrity during handling. Aluminium-protected housing for block weights Suitable for block weights up to 5 kg Calibrated classes F1–M3 compatible Internal padding for secure storage Safe storage that preserves calibration The KERN aluminium shell provides a rigid barrier against impacts and abrasion, while the padded interior prevents micro-movements that can affect a mass artefact’s calibration. For laboratories and calibration shops where traceability and repeatability matter, a dedicated protective case reduces the risk of accidental knocks and environmental contamination. The solid construction helps maintain the declared mass values and extends the service life of the weights, contributing to fewer recalibrations and more predictable maintenance intervals. Compatibility with calibration classes and handling benefits Designed specifically for block weights and compatible with classes F1–M3, this case supports common metrological workflows and storage protocols. The internal layout is suited to a standard block form and secures items up to 5 kg, ensuring conformity with class-specific handling. Using a dedicated case reduces handling time during inspections and audits and simplifies storage logistics in a busy workshop or calibration room. Clear class compatibility also aids procurement decisions, aligning the storage solution with formal calibration schedules and quality management systems. Lightweight design for workshop efficiency Constructed from aluminium, the case remains lightweight (approx. 1.25 kg) while offering durable protection, making it practical to move between benches, labs and transport crates without adding excessive bulk. The reduced weight simplifies manual handling and lowers transport effort when compared with heavier protective solutions, yet the material resists corrosion and everyday wear. This balance of low mass and high protection supports efficient workshop routines and helps maintain the condition of precision masses across frequent use.
