Calibration vs Validation
Introduction
Calibration and validation are often used interchangeably,
but they serve different purposes in quality and compliance systems.
Understanding the difference is essential for organizations operating in
regulated environments.
What Is Calibration?
Calibration compares an instrument’s measurement to a known
reference standard to determine accuracy. It identifies measurement errors and
ensures instruments remain within acceptable limits.
Calibration applies to instruments such as:
- pH and
conductivity meters
- Temperature
sensors
- Pressure
gauges
- Balances
and micropipettes
- Flow
and electrical instruments
What Is Validation?
Validation confirms that a system, process, or equipment
performs consistently as intended. It focuses on demonstrating suitability for
use rather than just measurement accuracy.
Validation is commonly applied to:
- HTST
systems
- Environmental
monitoring systems
- HVAC
systems
- Controlled
process equipment
Why Both Are Important
Calibration ensures measurement accuracy, while validation
confirms process reliability. Together, they support compliance, quality
assurance, and operational confidence.
