Definition: Consistency of temperature throughout a refrigerated space. High uniformity means minimal temperature gradient; low uniformity indicates significant temperature variation.
Measurement: Standard deviation or range (max – min) of temperatures at multiple locations.
Target Standards:
- Excellent uniformity: ±1°C range
- Good uniformity: ±2-3°C range
- Poor uniformity: ±5°C+ range (requires correction)
Why It Matters:
- Ensures all products receive adequate temperature control
- Critical for pharmaceutical validation
- Indicates proper air circulation and equipment sizing
