Gage Block Calibration Services
Quality Testing Calibration (QTC) provides ISO/IEC 17025 accredited gage block calibration services to support manufacturers, laboratories, and quality teams that rely on dimensional standards for accurate inspection and measurement. Proper gage block calibration protects measurement integrity across micrometers, calipers, height gages, and other precision instruments.
Our gage block calibration services are NIST-traceable and performed under an accredited quality system. Certificates include documented measurement uncertainty suitable for audits and quality compliance programs.
ISO/IEC 17025 Accredited & NIST-Traceable
QTC performs gage block calibration under ISO/IEC 17025 accreditation as recognized by A2LA. Accredited dimensional capability and uncertainty are defined in our current scope:

Accredited Gage Block Calibration Range
According to QTC’s current A2LA Scope of Accreditation (Cert. No. 4699.01), accredited gage block calibration is listed as:
| Parameter | Accredited Range | CMC (±) |
|---|---|---|
| Gage Blocks | 0.02 to 0.1 in | 5.7 µin |
| Gage Blocks | >0.1 to 4.0 in | (5.1 + 2.0L) µin |
In the uncertainty expression above, L represents the nominal length in inches. Actual measurement uncertainty may vary depending on the specific gage blocks submitted and calibration conditions.
Gage Block Calibration Methods
Gage block calibration is performed using controlled comparison techniques against certified master blocks in a temperature-controlled environment. The process verifies dimensional accuracy and supports traceable corrections for inspection and measurement applications.
- Verification across applicable lengths within the gage block set
- Documented results and accredited uncertainty reporting
- Calibration certificates suitable for audits and quality records
If your gage block calibration program requires defined acceptance criteria, reporting formats, or decision rules, those requirements can be addressed at the time of quote.
