Compare actual thermal performance against the standard’s requirements. A typical failure is —Class 2 incubators must maintain ≤ ±0.5°C at 37°C, but many aging units show ±2.0°C.
Draft an internal certificate stating: "Equipment [ID] has been verified to conform to DIN 12880-2007 05.pdf. All performance criteria meet Class [X] requirements. Verification date: [DD.MM.YYYY]. Next verification due: [annual date]."
To claim full , your laboratory must address three interconnected pillars: Performance Qualification , Safety Integration , and Documentation .
This test measures how quickly an appliance returns to its setpoint and remains within the allowed deviation after the door is opened for 30 seconds. Technical and Safety Scope
One-time compliance is insufficient. The standard expects ongoing surveillance. Implement a :
| Non-Conformity | Why It Fails | Solution | |----------------|--------------|----------| | Using a single-point calibration only | Standard requires multi-point spatial mapping (min. 5 positions, often 9) | Perform a 9-point thermocouple study annually | | No documentation of loading conditions | Performance changes with load; empty-chamber data is insufficient | Repeat mapping at 50%, 75%, and 100% shelf load | | Ignoring recovery time after door openings | Critical for incubators and stability chambers | Officially measure and document recovery in OQ | | Missing safety alarm test log | Standard requires proof of alarm function | Weekly or monthly alarm activation test with signature | | Using non-traceable thermometers | Unacceptable for regulated GxP environments | Use NIST/DAkkS/PTB calibrated reference sensors |
