Temperature Humidity Vibration Combined Test Chamber

The Temperature-Humidity-Vibration Combined Test Systemis an advanced reliability testing platform that integrates climatic stress with mechanical vibration. By combining a high-performance environmental chamber with an electrodynamic or mechanical shaker, this system allows you to simulate the complex, multi-dimensional stresses that products face in real-world operating environments. It is engineered specifically to identify synergistic failure modes that single-stress tests might miss, making it an indispensable tool for safety screening and durability validation of critical assemblies.

Standards

GB/T 2423.35‌ Procedures for combined temperature, humidity, and vibration testing, including environmental condition setting and performance monitoring

‌GB/T 28046.3‌ Focuses on automotive electrical and electronic systems, classifying severity by component installation location (e.g., engine, body) to simulate actual operating environments

GB/T 44279-2024 Covers combined temperature-humidity-vibration-low-pressure testing, enhancing simulation capabilities for extreme environments (e.g., high altitude or tropical climates)

IEC 60068-2-53 Test methods for electrical and electronic products under combined temperature, humidity, and vibration environments, emphasizing accelerated exposure of product failure modes through multi-stress superposition

ISO 16750-3 Prescribes coordinated testing of mechanical loads (vibration) and temperature conditions for automotive electronic equipment, ensuring component durability during vehicle operation
