Gage Block & Gage Block Set Calibration Services
The blocks are the bottom of your traceability pyramid — everything above them inherits their truth.
ACS Calibration delivers NIST-traceable, audit-ready gage block services, available at the ACS central lab or directly on-site at facilities across the Southeast. Calipers, micrometers, height gages, and indicators are all on our accredited dimensional scope, so ISO/IEC 17025 accredited certificates are available on request.
Where Traceability Touches Steel
Gage blocks are where a shop’s traceability chain becomes physical — the standards your mics, calipers, and height gages get checked against. Wear from wringing, corrosion from handling, and burrs from drops all move a block off its nominal, and every in-house check performed with it inherits the shift.
We calibrate gage blocks and complete sets with NIST-traceable verification of each block, documenting deviations from nominal with as-found data — individual blocks flagged when they leave grade. The micrometers and calipers those blocks check belong on the same audit-ready cycle.
What You Get With Every Calibration
- NIST-traceable calibration certificate with real measurement data — not just a pass/fail sticker
- As-found and as-left readings, so drift is documented
- ISO/IEC 17025 accredited certificate with reported uncertainty — on request
- Calibration label with due date, plus a reminder before your next calibration is due
