Is Prism's balance calibration NABL accredited?

Yes. Prism holds NABL accreditation CC-2480 under ISO/IEC 17025:2017. Balance and pipette calibration accepted for GMP, GLP, FSSAI, ISO 9001 audits.

What is ISO 8655 pipette calibration?

Gravimetric method per ISO 8655 — pipette accuracy measured by weighing dispensed water at 10%, 50%, 100% volume using an analytical balance and thermometer. Required for GMP/GLP labs.

How often should a Spring Balance be calibrated?

ISO 9001 and ISO/IEC 17025 recommend calibrating a spring balance at least once every 12 months. Instruments in critical processes, harsh environments, or subject to regulatory audits (FDA, GPCB) may require calibration every 6 months or as specified by the manufacturer.

Does Prism provide NABL-accredited Spring Balance calibration?

Yes. Prism Calibration Centre holds NABL accreditation CC-2480 and provides fully traceable spring balance calibration with NABL-signed certificates accepted by ISO auditors, FDA, GPCB, CPCB, and customs authorities worldwide.

Can Prism calibrate Spring Balance onsite at our facility?

Yes. Prism dispatches NABL-certified engineers with portable reference standards to calibrate spring balance instruments onsite at your facility in Ahmedabad, Surat, Vadodara, Rajkot, and across Gujarat - with zero instrument removal and zero production downtime.

— WHAT IS SPRING BALANCE CALIBRATION —

What Is Spring Balance Calibration & Why Does It Matter?

Think of a quality lab that relies on a spring balance 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.

Spring Balance 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.

Check

Compare readings against a NABL-traceable reference standard across the full measurement range.

Correct

Adjust or document deviations so your instrument reads within accepted tolerance.

Certify

Issue a NABL-accredited certificate (CC-2480) with full traceability documentation.

— OUR PROCESS —

Calibration Process — Step by Step

Receipt & Identification

Spring balance received. Scale range, graduation, make, and serial number recorded. Balance inspected for pointer alignment, spring fatigue, and legibility of scale markings.

Zero Check & Suspension

Balance suspended vertically in calibration rig. Zero confirmed at no-load. Any zero offset noted before applying loads.

5-Point Force Calibration

Dead weights applied at 5 setpoints: ~10%, 25%, 50%, 75%, and 100% of full scale. Applied force calculated from certified mass × local gravity (g = 9.7961 m/s² for Gujarat).

Error & Hysteresis Check

Scale error (indicated minus applied) measured at each point. Hysteresis checked by loading and unloading. Standard deviation and maximum error computed.

Uncertainty Calculation

Expanded uncertainty (k=2) per GUM. Contributions: reference mass uncertainty, local gravity, pointer reading resolution, and repeatability.

NABL Certificate Issue

NABL CC-2480 certificate reporting applied force (N), indicated value, error, uncertainty (k=2), and traceability to NPL/BIPM.

Traceable References

All non-NABL work uses NABL-certified reference standards — readings are still reliable and defensible.

Faster Turnaround

Without full NABL documentation, instruments return faster — ideal for urgent production schedules.

Cost-Effective

Non-NABL calibration costs less — practical for large batches or routine periodic checks.

Onsite or In-Lab

Available at your facility or at our Vatva lab — same quality, more flexibility.
