From data centers overheating and shutting down, to port machinery corroding and failing, to vaccines in cold chain logistics losing efficacy due to temperature deviations-equipment is constantly challenged by its operating environment. When exposed to abnormal temperature and humidity conditions over time, failure becomes an unavoidable issue. This highlights the critical importance of temperature and humidity environmental testing.
Typical Failure Cases
- Data Center Server Shutdown: Air conditioning failure led to excessive temperature and humidity, causing servers to overheat and trigger protective shutdowns. This resulted in widespread service outages for websites and applications for several hours.
- Port Crane Failure: Control systems exposed to humid sea air experienced severe corrosion on internal circuit boards, leading to insulation degradation, short circuits, and complete system failure.
- Warehoused Precision Instruments Damaged: High-precision optical instruments stored in overly humid conditions suffered from oxidized metal contacts and mold growth on lenses, resulting in significant performance degradation and batch scrapping.
Temperature and humidity are among the most critical environmental factors affecting product reliability. High temperatures accelerate component aging, low temperatures cause material embrittlement, and humidity promotes corrosion, short circuits, and mold.
