Humidity Testing

Humidity Testing

Humidity Testing is a suite of standardized environmental tests performed in testing labs to evaluate the prolonged effect of humidity on a product or material. Humidity can mitigate a product’s performance, accelerate corrosion, cause moisture diffusion issues, induce mechanical failure, and result in other detrimental effects over a product’s lifetime. These effects can be studied in a laboratory using controlled environmental chambers that simulate 100% relative humidity under constant or cyclic temperature and humidity conditions. It is routinely performed independently or as a part of accelerated aging tests on products and devices following industry standards or custom set-ups.

Humidity testing is a critical component in material selection, product design, product reliability testing, and ensuring regulatory compliance for products. It is used to determine material degradation, mechanical, optical, and sealant failures in a wide range of products from electrical components, pharmaceutical containers, plastics, metals, epoxy coatings, computers, automotive parts, etc.

Infinita Lab network testing labs provide ASTM, ISO standardized testing, and our experts offer consultation for custom testing setup suitable for a client’s specific service conditions. A specific problem focussed approach helps our clients based in the USA and other countries across the globe to achieve the best probable solution.

Common Uses of Humidity Testing

• It can be used to research how contaminants affect a system.
• It is one of the most used accelerated reliability testing techniques for electronics.
• For excessive acceleration, rigorous humidity testing is used.

Advantages of Humidity Testing

• The test is simple to perform and is easily available in labs.
• It is an extremely efficient technique for plastic parts.
• There are different types of humidity tests available.
• As humidity testing has been and continues to be a common test in both the academic and industrial worlds, there is a wealth of information about the effects of various humidity tests on various structures and materials available.
• In addition to employing humidity testing as a reliability test, it is also a great validation test.

Limitations of Humidity Testing

• When humidity and high temperature are coupled, the test is typically much more rigorous and effective than either humidity or temperature alone would be.
• It is possible to anticipate reliability, however there are some restrictions.
