— WHAT IS MEASURING TAPE CALIBRATION —
A stretched or shrunk steel tape gives wrong dimensions on every measurement — leading to layout errors, construction defects, and rejected parts. Measuring tape calibration verifies graduation accuracy across the full tape length against NPL-traceable references per IS 1270.
Measure
Tape measured at 10+ points across full length against NPL-traceable references in controlled environment.
Assess
MPE per IS 1270 / OIML R 35 assessed. Hook condition, graduation clarity verified.
Certify
NABL CC-2480 certificate with errors at all measured points — accepted by ISO 9001 & legal metrology.
— INSTRUMENTS COVERED —
Steel Tapes · Steel Scales · Radius Gauges · Wire Gauges · IS 1270 / OIML R 35 · NABL accredited
Steel measuring tapes for general linear measurement from 2 m to 50 m.
Steel scales and rules for short-range linear and depth measurement.
Radius gauges for measuring concave and convex radii on machined parts.
Wire gauges for measuring wire diameter and sheet metal thickness.
— OUR PROCESS —
Instrument received, tagged, type and range documented. Tape rewind, blade condition, and hook condition noted.
Graduation clarity, hook condition, blade kinks, and surface rust checked. As-found condition recorded.
Tape or scale measured at 10+ points against NPL-traceable length references in controlled environment.
Maximum permissible error (MPE) per IS 1270 / OIML R 35 assessed. Errors plotted against scale length.
Final readings confirmed and recorded. Pass/fail determined. Correction table prepared if required.
NABL CC-2480 certificate with as-found data, errors at measured points, uncertainty (k=2), IS 1270 / OIML R 35 traceability.

NABL Accreditation Standard
Prism holds NABL CC-2480 under ISO/IEC 17025:2017. Measuring tape and misc instrument certificates are valid for ISO 9001, IATF 16949, legal metrology, and all audit purposes.
— NON-NABL CALIBRATION —
For routine maintenance or workshops not needing NABL certification — cost-effective non-NABL measuring tape calibration with the same engineers and traceable references.
All non-NABL jobs use NPL-traceable length standards — only the certificate type differs.
Non-NABL tape jobs completed faster — ideal for urgent maintenance or large bulk batches.
Priced lower than NABL — right choice for internal checks and non-audit use cases.
Short tapes onsite; long tapes (10m+) at our controlled Ahmedabad lab.
— AREAS WE SERVICE —
Onsite calibration for short tapes and scales. Collection and delivery for long tapes. All Gujarat GIDC zones covered.
Why Choose Prism
Since 2004, every NABL measuring tape and misc instrument certificate issued by Prism has been accepted by ISO, IATF, BIS, FDA, and GPCB auditors.
