What standards govern calibration in India?
In India, instrument calibration is governed by national and international standards to ensure measurement accuracy, traceability, and compliance. The most widely followed framework is provided by the National Accreditation Board for Testing and Calibration Laboratories (NABL), which accredits calibration laboratories as per globally recognized requirements.
- ISO/IEC 17025 — General requirements for competence of testing and calibration laboratories
- National Accreditation Board for Testing and Calibration Laboratories (NABL) accreditation and traceability requirements
- Bureau of Indian Standards (BIS) guidelines and relevant Indian Standards (IS)
- Traceability to national standards maintained by National Physical Laboratory (NPL)
- Quality management standards such as ISO 9001 and safety frameworks like ISO 45001
Following these standards ensures that calibrated instruments provide reliable readings, support regulatory compliance, and meet audit requirements across industries.
Calibration practices in India are typically guided by:
The exact requirements can vary depending on the instrument type, the industry involved, and whether the calibration is being used for quality control, safety assurance, regulated production, inspection records, or customer audits.
In practice, good calibration should demonstrate technical competence, suitable reference standards, proper records, and traceability to recognized measurement standards.
