Single gauge block 1.23 mm — DIN EN ISO 3650, grade 0 (Metav IndustryLine)

Single gauge block 1.23 mm for traceable dimensional referencing in inspection benches and calibration laboratories

• DIN EN ISO 3650, tolerance grade 0
• Hardened special steel construction
• Nominal size 1.23 mm for calibration tasks

Reproducible accuracy for calibration and inspection

A compact reference element engineered to the DIN EN ISO 3650 standard, this single gauge block delivers the dimensional reliability required in calibration and quality assurance workflows. The block’s grade 0 tolerance ensures tight conformity to nominal dimensions, reducing uncertainty when comparing measuring instruments or building a set of reference standards. Designed as a reference rather than a measuring instrument, this component supports consistent results across repeated comparative checks and helps maintain traceability chains within laboratory environments.

Durable construction that retains reference over time

Manufactured from hardened special steel, the block resists wear and maintains flatness and parallelism under normal handling, which preserves its role as a stable datum. The choice of material reduces the need for frequent refurbishment and limits measurement drift, so reference assemblies and comparator setups remain dependable. The small mass and compact geometry also make handling straightforward during assembly of gauge stacks, while the specified cross-section dimensions contribute to mechanical stability in stacking and clamping situations.

Practical integration into workshop and laboratory routines

Supplied as a single reference length, the unit integrates easily into existing gauge block sets or serves as a targeted reference for setting up micrometres, calipers and comparator jaws. Clear conformity to the DIN EN ISO 3650 standard simplifies documentation and quality records, aiding acceptance during internal audits or supplier assessments. Where tight tolerances are essential, this block functions as a quick, traceable check to confirm instrument behaviour before critical measurements are taken.

FAQ

What does tolerance grade 0 mean for a gauge block?
Tolerance grade 0 indicates a very tight dimensional tolerance under DIN EN ISO 3650; the single gauge block 1.23 mm meets these limits and is suitable where high reproducibility of the reference dimension is required.

Is this gauge block suitable for use as a calibration reference?
Yes. The block is designed as a reference element and, when used within a controlled process, supports calibration and comparative checks of measuring instruments and gauge stacks.

Which material is used and how does this affect wear?
The block is made from hardened special steel, chosen for its wear resistance and dimensional stability, which helps to maintain the reference dimension through regular use.

Can the block be stacked with other gauge blocks?
The geometry and cross-section dimensions are compatible with standard gauge-block stacking procedures, allowing integration into sets for compound lengths and reference assemblies.

How should the block be stored to preserve accuracy?
Store the block in a clean, dry environment and avoid abrasive contact; typical practice is to keep gauge blocks in a protective case or drawer to prevent nicks and contamination.
