- Resolution down to 0.0001 mm (0.1 µm) using Zeiss CMM and surface plate reference.
- Gauge block sets (Grade K, Grade 00, Grade 0, Grade 1) available as reference standards.
- Temperature-controlled calibration room at 20°C ± 0.5°C for dimensional stability.
- Certificate includes measurement result, expanded uncertainty, and gauge R&R data on request.

Dimensional Calibration for Automotive in Gujarat
Gujarat's automotive sector — Tata Motors (Sanand), Maruti Suzuki supply chain, Honda, Hero, and 1000+ Tier 1–2 component suppliers — demands dimensional calibration with gauge R&R (repeatability and reproducibility) studies to IATF 16949 requirements. Prism provides NABL-certified dimensional calibration with measurement uncertainty values that support gauge R&R analysis.
Temperature-Controlled Dimensional Calibration Room
Dimensional measurements are highly sensitive to temperature — steel expands 11.7 µm per metre per °C. All dimensional calibrations at Prism are performed in our temperature-controlled calibration room maintained at 20°C ± 0.5°C (as per ISO 1 — the international standard reference temperature for dimensional measurement). This ensures your calibration results are directly comparable to manufacturer specifications.
Frequently Asked Questions
What is the smallest resolution Prism can calibrate for dimensional instruments?
Prism calibrates instruments with resolution down to 0.0001 mm (0.1 µm) using reference gauge blocks (Grade 00) and a Zeiss Contura CMM with probe qualification.
Can Prism calibrate large-range vernier calipers up to 2000 mm?
Yes. Prism calibrates vernier calipers, digital calipers, and height gauges up to 3000 mm range using calibrated steel rules and reference length standards.
Does Prism calibrate CMM machines?
Prism calibrates CMM probe systems (qualification spheres, styli) and provides reference gauge blocks for CMM performance verification. Full CMM volumetric performance verification is done by CMM OEM service engineers.
Is dimensional calibration required for IATF 16949?
Yes. IATF 16949 Clause 7.1.5.3 (MSA) requires all gauging instruments in production to be calibrated by NABL-accredited labs, with measurement uncertainty values for gauge R&R studies.
How does Prism handle large plug gauges and ring gauges?
Large plug gauges (up to 100 mm diameter) and ring gauges are calibrated using a calibrated CMM or precision bench micrometer. Gauges outside Prism's scope are calibrated through accredited partner labs.
