End gauge 25 mm, DIN EN ISO 3650 — Grade 1, hardened special steel (Metav IndustryLine)

The End gauge 25 mm, DIN EN ISO 3650, Grade 1 serves as a precision reference standard for dimensional inspection and laboratory calibration in metrology and quality-control environments.

• DIN EN ISO 3650 Grade 1 accuracy
• Hardened special steel construction
• Nominal size 25 mm reference
• Precision ground cross-section 35 x 9 mm

Consistent reference accuracy for routine inspection

The block is manufactured to DIN EN ISO 3650 and specified as Grade 1, providing a reliable tolerance band for comparative measurements and gauge verification. As a compact reference of 25 mm, this gauge block is ideal where a stable, short-length standard is required. The hardened special steel body and precision-ground faces reduce wear and preserve dimensional integrity over repeated use, which supports dependable comparative checks on micrometres, callipers and fixture settings.

Durable construction that reduces measurement uncertainty

A robust cross-section of 35 x 9 mm (applicable from 10.1 mm nominal sizes) gives the block mechanical stiffness that limits flexing during handling. The special steel, hardened finish provides corrosion resistance and surface stability, so the block maintains form under workshop conditions. With a mass of approximately 0.071 kg, the piece is easy to handle yet substantial enough to avoid inadvertent movement, helping to reduce operator-induced measurement scatter and improving repeatability.

Practical benefits for calibration and inspection workflows

Using a standardised reference such as this supports faster, more consistent quality control steps: the Grade 1 specification makes it straightforward to rank inspection tools, to carry out comparative adjustments and to document conformity with internal procedures. The compact format suits bench-top labs and on-machine checks where space is limited, while the precision ground surfaces enable accurate seating against mating faces for immediate, reproducible readings.

Traceability, documentation and application contexts

The unit is supplied with clear product identifiers for inventory and audit purposes: nominal size 25 mm, compliance DIN EN ISO 3650, and a GTIN for traceability. Typical applications include verification of small gauges, cross-checking external micrometre settings and serving as a reference for inspection jigs. The design is optimised for workshop and laboratory environments where compact, durable reference standards are required rather than large gauge stacks or specialised wringing systems.
