Regulatory Compliance & Global Standards

Calibration laboratories must adhere to stringent regulatory and quality standards to ensure accurate, reliable, and traceable measurement results. These standards not only assure data integrity and measurement validity but also support compliance with international regulatory bodies and customer-specific requirements.

  • ISO/IEC 17025:2017: General requirements for the competence of testing and calibration laboratories. It ensures valid results, technical proficiency, and traceability.
  • 21 CFR Part 11 (FDA): Governs electronic records and signatures—applicable if digital systems are used in calibration documentation.
  • Good Manufacturing Practices (GMP): Ensures measurement equipment used in regulated environments (like pharma) is properly calibrated and traceable.
  • ISO/IEC Guide 98 (GUM): Guide to the Expression of Uncertainty in Measurement – for reporting uncertainty.
  • OIML R111: International Recommendation for Weights of Various Accuracy Classes (E1, E2, F1, F2, M1, etc.)
  • OIML R 76: - It specifies the metrological and technical requirements for non-automatic weighing instruments.
  • ISO 4787: Guidelines for the use and calibration of volumetric glassware.

Frequently Asked Questions

Frequently Asked Questions

What is mass calibration?

Mass calibration is the process of verifying and adjusting the accuracy of weights and weighing instruments (balances, scales) using traceable reference standards to ensure correct mass measurement.

How often should I calibrate my weighing instruments?

Typically every 6 to 12 months, depending on regulatory requirements (e.g., GMP), frequency of use, and criticality. Your internal SOPs or QMS may define exact intervals.

Are your mass calibrations traceable to national/international standards?

Yes. All calibrations are traceable to NPL (India) and OIML/NIST through NABL-accredited reference standards.

What are OIML classes (E1, F1, M1)?

These classes define the accuracy level of weights.
• E1/E2: High-precision laboratory use
• F1/F2: General lab or industrial calibration
• M1/M2: Industrial or trade use

What is volume calibration?

Volume calibration involves determining the actual capacity of volumetric devices (e.g., pipettes, flasks, burettes, tanks) using traceable standards to ensure accurate liquid measurement.

What methods do you use for volume calibration?

We use gravimetric and volumetric methods depending on the instrument type, volume range, and accuracy class.

Can volume calibration be performed onsite?

For fixed installations like tanks or process equipment, yes. For glassware or micropipettes, lab-based calibration is recommended for higher precision.
