What is NABL Calibration ?
NABL stands For National Accreditation Board for Testing and Calibration Laboratories . It is India's accreditation body Responsible for assessing calibration Laboratories according to ISO/IEC 17025 Requirements .
NABL calibration ensures that an instrument's readings are compared against Traceable standards to Verify measurement Accuracy .
Calibration verifies whether an instrument is providing accurate readings and ensures traceability to national or international measurement Standards .
Why Calibration Really Matters
1. Accurate Measurements
Calibration helps eliminate measurement drift and ensures reliable results .
2. Compliance Requirements
ISO audits and quality management systems require calibrated equipment .
3. Reliable Data
Business decisions depend on trustworthy measurement results .
4. Improved Safety
Calibration reduces risks associated with inaccurate measurements .
How NABL Calibration Works
Step 1: Instrument Identification
The instrument is tagged and calibration history is reviewed .
Step 2: Initial Inspection
The instrument is checked for damage and physical condition .
Step 3: Testing Against Standards
Measurements are compared with traceable reference standards .
Step 4: Adjustment
Necessary corrections are made if deviations are observed .
Step 5: Documentation
A detailed calibration certificate is generated .
Step 6: Labeling
A calibration sticker indicates calibration status and due date .
