— WHAT IS TENSILE TESTING MACHINE CALIBRATION —
Think of a quality lab that relies on a tensile testing machine for daily measurements. If it has drifted even slightly from its true value, every reading becomes unreliable — leading to defective products, failed audits, or safety risks. Regular calibration is the only way to confirm your instrument is telling the truth.
Tensile Testing Machine calibration means comparing its readings against a NABL-traceable certified reference standard at multiple test points, recording the deviations, adjusting where possible, and issuing an NABL certificate — accepted by ISO 9001, IATF 16949, and all quality auditors.
Compare readings against a NABL-traceable reference standard across the full measurement range.
Adjust or document deviations so your instrument reads within accepted tolerance.
Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. UTM calibration certificates accepted by IATF 16949, ISO 9001, NADCAP, and all material testing audit bodies.
— NON-NABL CALIBRATION —
For routine maintenance, bulk calibration, or internal QC checks where a full NABL certificate is not mandatory — Prism offers cost-effective non-NABL calibration using the same NABL-traceable reference standards and trained engineers.
All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.
Without full NABL documentation, instruments return faster — ideal for urgent production schedules.
Non-NABL calibration costs less — practical for large batches or routine periodic checks.
Available at your facility or at our Vatva lab — same quality, more flexibility.
— AREAS WE SERVICE —
Engineers carry certified force standards to your facility. Onsite UTM calibration with no machine downtime.
Why Choose Prism
Since 2004, every NABL UTM certificate issued by Prism has been accepted by IATF 16949, ISO 9001, and NADCAP auditors — no rejections.
