Damp Heat Test Chamber / Steady state test
Damp Heat Steady State Testing
Damp Heat Steady State Testing is an essential environmental testing method used across numerous industries to evaluate the long-term effects of high humidity and temperature on various materials, products, and components. This test is especially relevant in assessing the reliability and performance of electronic and electrical products intended for use in tropical or high-humidity environments. The primary goal is to detect potential failures, corrosion, degradation of materials, or loss of insulation resistance that may result from prolonged exposure to heat and moisture.
Our environmental laboratory is equipped with state-of-the-art damp heat test chambers that allow us to carry out steady state testing under carefully controlled conditions, ensuring accurate and repeatable results. This testing service is part of our broader suite of environmental and reliability testing offerings, designed to help manufacturers validate product robustness and meet quality assurance standards.
The test is commonly used in industries such as:
- Automotive and Transportation – to test the durability of on-board electronics, connectors, sensors, and control units.
- Aerospace and Defense – for avionics, mission-critical systems, and humidity-sensitive components.
- Consumer Electronics – to assess corrosion resistance and operational integrity of devices exposed to humid climates.
- Telecommunications – testing circuit boards, enclosures, and connectors for moisture ingress and degradation.
- Industrial Equipment and Instrumentation – validating materials used in harsh operating environments.
- Construction Materials and Coatings – evaluating rust, blistering, and adhesion of materials in high humidity.
Test Parameters and Conditions
Our Damp Heat Steady State Test can be conducted under several standardized temperature and humidity combinations. The exact test profile is selected based on the product’s expected application environment and industry standards.
We offer the following common test conditions:
| Temperature | Humidity (Relative Humidity) | Test Durations |
|---|---|---|
| 30 ± 2°C | 93 ± 3% RH | 12h, 16h, 24h, 48h |
| 30 ± 2°C | 85 ± 3% RH | 12h, 16h, 24h, 48h |
| 40 ± 2°C | 93 ± 3% RH | 12h, 16h, 24h, 48h |
| 40 ± 2°C | 85 ± 3% RH | 12h, 16h, 24h, 48h |
