Calibration discipline

What is Length & Dimensional calibration?

Quick answer

Length & dimensional calibration compares dimensional instruments — calipers, micrometers, dial indicators, gauge blocks — against higher-accuracy length standards to determine error and measurement uncertainty. Techmaster’s ISO/IEC 17025:2017 lab is traceable to the SI metre (m).

Even tiny dimensional deviations can cause scrap, mis-assembly and quality disputes — especially in precision machining, electronics and semiconductor work. Periodic calibration of dimensional instruments controls this risk and satisfies ISO 9001, IATF 16949 and AS9100 requirements.

Techmaster calibrates using ISO/IEC 17025 methods with reference gauge-block sets and standards traceable to the international metre. Certificates are accredited by ANAB (USA) and recognized worldwide via ILAC-MRA.

Measurement range

Typical measurement ranges & CMC

The table below lists typical parameters & measurement ranges for this discipline.

Parameter / Instrument Typical measurement range CMC / Measurement uncertainty
Gauge blocks 0,5 – 100 mm [Verify against scope]
Calipers 0 – 300 mm (up to 1000 mm) [Verify against scope]
Micrometers 0 – 100 mm [Verify against scope]
Dial indicators 0 – 25 mm [Verify against scope]
Tapes & rules 0 – 10 m [Verify against scope]

Note: The ranges & CMC below are typical reference values. Please verify against Techmaster’s official Scope of Accreditation before publishing — actual CMC depends on the reference standard, method and measurement conditions.

Standards & traceability

Reference standards & traceability

Length measurements are traceable to the SI metre (m) through grade K/0 reference gauge-block sets and length standards, following reference standards such as ISO 3650 (gauge blocks) and the JCGM guides on measurement uncertainty.

Q & A

Frequently asked questions

How often should calipers and micrometers be calibrated? +
A 12-month interval is common, but it should be shortened for heavily used tools, harsh environments, or where your quality system requires it. Techmaster advises a suitable interval and sends automatic reminders.
Can Techmaster calibrate gauge blocks? +
Yes. Techmaster calibrates gauge blocks and many other dimensional instruments, with traceability to the international metre and ISO/IEC 17025 certificates.
Can length calibration be done on-site? +
Many hand tools can be calibrated on-site at your facility. Equipment that needs a stable environment (20°C) is best calibrated in the lab to preserve accuracy.
Are Techmaster length certificates internationally recognized? +
Yes. The lab is ISO/IEC 17025:2017 accredited by ANAB (USA); certificates are recognized across 100+ ILAC-MRA member economies.
