UTM Calibration Services

Our UTM calibration services verify the force-measuring system of universal testing machines as per IS 1828 (Part 1) and ISO 7500-1. Using calibrated proving instruments, we apply known forces across each range of your UTM, calculate the relative errors and repeatability, and classify the machine (for example Class 1 or Class 2).

We calibrate mechanical, electronic, servo controlled and computerised UTMs and electromechanical tensile testers of all makes, on site, with NABL accredited certificates.

  • NABL accredited (CC-2359)
  • 12 offices across India
  • 30+ years of experience

Service Details

What is checked during UTM calibration

  • Relative indication error at each calibration point
  • Relative repeatability error
  • Relative reversibility error (where required)
  • Zero error and resolution of the force indicator
  • Accessory checks such as extensometer calibration, where in scope

Why calibrate your UTM?

  • Tensile results on TMT bars, plates and fasteners depend directly on force accuracy
  • Required by ISO 9001, IATF 16949 and ISO/IEC 17025
  • Customers and third-party inspectors ask for a valid certificate
  • Early detection of hydraulic or sensor problems

Our calibration process

  • Enquiry and scope: share the machine type, make, capacity and ranges to be calibrated.
  • Scheduling: our engineer visits your site with calibrated reference standards (proving rings / load cells, reference blocks, etc.).
  • Pre-checks: visual and functional inspection; minor adjustments where needed.
  • Calibration: measurements at the specified points per the applicable standard, with repeatability and error calculations.
  • Certificate: a traceable calibration certificate showing the class, errors and measurement uncertainty.

Frequently Asked Questions

How long does UTM calibration take?

Usually a few hours per machine, depending on the number of ranges and its condition.

What is a Class 1 UTM?

Under ISO 7500-1 / IS 1828, a Class 1 machine has relative indication and repeatability errors within plus or minus 1 percent. Many tensile test standards require Class 1.

Can you calibrate UTMs of other brands?

Yes. We calibrate UTMs of all Indian and imported makes.
