Gauge block 5.5 mm — Grade 1 length standard, DIN EN ISO 3650

The gauge block 5.5 mm is a precision length standard designed for dimensional verification and setting tasks in workshops and inspection benches, compliant with DIN EN ISO 3650 and intended for routine metrological use.

• Gauge block 5.5 mm nominal length
• Grade 1 tolerance to DIN EN ISO 3650
• Hardened special steel construction
• Compact cross-section 30 × 9 mm

Precision that keeps production on spec

Manufactured to Grade 1 tolerances under DIN EN ISO 3650, this small length standard gives a dependable reference for calibration chains and comparative measurements. The specified 5.5 mm nominal length and careful finishing reduce measurement uncertainty at the reference stage, which in turn lowers the risk of rework and out-of-tolerance production. The graded accuracy supports repeatable results across routine checks and gauge setting, improving throughput by limiting doubt in pass/fail decisions while maintaining traceable documentation for quality systems.

Compact design for everyday metrology

A compact cross-section and low mass make the block easy to handle during frequent checks: the applicable cross-section for this nominal range is 30 × 9 mm, and the component mass is approximately 0.009 kg. Those physical characteristics mean fewer errors from leverage or operator-induced bending when compared with longer or heavier standards, so bench-based measurement remains straightforward. The small footprint also simplifies storage in gauge sets and reduces the space required in inspection cupboards, helping maintain an organised measurement workplace.

Made to last and support quality systems

Constructed from hardened special steel, the block is intended to offer wear resistance and dimensional stability under normal workshop conditions, supporting long service life and consistent calibration intervals. Robust material choice directly translates into lower lifecycle cost because durable standards maintain form and permit longer intervals between corrective regrinding or replacement. In applications where reproducibility is critical—setting plug gauges, verifying micrometre zero settings or supporting master comparisons—this grade and construction provide an economical balance of precision and resilience.

FAQ

What tolerance class does this gauge block meet?
The gauge block meets Grade 1 tolerances in accordance with DIN EN ISO 3650, offering a level of accuracy suitable for workshop inspection and comparative measurements.

Which material is used and how does it affect service life?
Made from hardened special steel, the block provides increased wear resistance and dimensional stability compared with softer materials, which helps to extend service life under normal handling and reduces frequency of maintenance.

Is the block suitable for setting micrometres and gauges?
Yes; the 5.5 mm reference is appropriate for setting micrometres, checking gauge blocks and supporting everyday calibrations where a compact, accurate standard is required.

How should the gauge block be stored and handled?
Store the block dry and free from abrasive contaminants; keep it within a protective gauge set or wrap when not in use to preserve surface condition and accuracy.
