Gauge block 70 mm (DIN EN ISO 3650, Grade 1) – hardened special steel

The Gauge block 70 mm (DIN EN ISO 3650, Grade 1) is a precision reference block designed for laboratory and workshop calibration, suitable for setting comparators and verifying measuring instruments.

• DIN EN ISO 3650 Grade 1 accuracy
• Hardened special steel construction
• 70 mm nominal reference length
• Compact, workshop-ready format

Consistent reference accuracy for calibration procedures

The block serves as a precision reference for routine calibration and verification tasks, delivering the stability expected from a Grade 1 standard under DIN EN ISO 3650. Its nominal length of 70 mm provides a commonly used reference point that integrates easily into gauge sets and comparator routines. Because the block is manufactured from hardened special steel, thermal and wear-related deviations are reduced, which supports repeatable measurements and lowers rework rates in production settings.

Durable construction that withstands regular handling

Manufactured from hardened special steel, this reference block combines toughness with fine surface finish to ensure long service life in a busy metrology bench or workshop environment. The solid build reduces susceptibility to knocks and abrasion, while the compact mass (approx. 0.17 kg) makes the block simple to position during setup. The specified cross-section (35 x 9 mm for sizes greater than 10.1 mm) provides sufficient rigidity for reliable contact during gauge-setting and comparator use without excessive bulk.

Practical integration into inspection workflows

As a standard reference item, the block is suitable for use in traceable routine checks, setting up calipers and micrometres, and establishing baseline measurements for quality control routines. The combination of DIN EN ISO 3650 compliance and Grade 1 classification helps maintain process conformity and supports audit documentation. Lightweight and compact, the block is easy to include in existing sets of gauge blocks or to store alongside other reference standards for efficient daily use.
