EN 60068-2-38 Temperature and Humidity Combined Testing
The EN 60068-2-38 test protocol is a crucial standard for ensuring the reliability and durability of electrical and electronic products under extreme environmental conditions. This test evaluates components, assemblies, and systems to determine their ability to withstand combined temperature and humidity stresses that they may encounter in real-world applications.
The combination of temperature and humidity can lead to significant degradation of materials and performance issues for electronic devices. By subjecting the product to controlled cycles of high and low temperatures alongside varying humidity levels, manufacturers can ensure that their products meet the required standards before deployment. This testing is particularly important in railway and transportation sectors where reliability and safety are paramount.
The test methodology involves placing specimens into a chamber designed to simulate real-world environmental conditions. The chamber can rapidly change between hot and cold temperatures while also adjusting relative humidity levels. Specimens undergo multiple cycles of temperature and humidity changes, typically ranging from -40°C to +85°C with corresponding humidity levels.
During the test, it is essential that the specimen remains within specified limits throughout each cycle. Failure to do so can indicate potential weaknesses in design or manufacturing processes. Compliance with this standard ensures that products are robust enough for use under harsh environmental conditions without compromising safety standards.
To perform these tests accurately requires specialized equipment capable of maintaining precise control over both temperature and humidity levels, as well as monitoring systems that log data throughout the entire process. Our laboratory employs state-of-the-art facilities to ensure accurate results every time, providing clients with confidence in their product's performance.
Understanding how different materials behave under combined thermal-humid conditions is critical for developing reliable products across various industries including transportation and railway sectors.
