What is the IEC60068 humidity test?

The significance of IEC60068 humidity test

The IEC60068 humidity test, also known as the humidity conditioning test, is a standard test method used to assess the performance and reliability of electronic equipment, components, and materials under different levels of humidity. This test is conducted to simulate the effects of humidity on products throughout their life cycle, ensuring their functioning even in harsh environmental conditions.

Humidity has a significant impact on electronic devices and can cause various issues such as corrosion, condensation, and electrical failures. By subjecting the products to controlled humidity conditions as per the guidelines set by the International Electrotechnical Commission (IEC), manufacturers can evaluate their resistance to moisture and ensure that they meet the required standards.

Test procedure and requirements

The IEC60068 humidity test involves subjecting the test specimens to specified levels of humidity for a defined period. The test is typically performed within a climatic chamber where the environment can be precisely controlled. The relevant parameters monitored during the test include temperature, relative humidity, condensation occurrence, and the duration of exposure to each humidity level.

The test specimens are placed in the climatic chamber and exposed to different humidity levels according to the product's intended operating conditions. The objectives of this test are to evaluate if the product withstands the specific humidity levels without any physical or functional degradation, assess the effects on mechanical, electrical, and chemical properties, and identify potential weak points that need improvement.

Benefits and applications

The IEC60068 humidity test offers several benefits to manufacturers, including:

Ensuring product reliability: By subjecting products to humidity testing, manufacturers can identify weaknesses and make design modifications to enhance their resistance to moisture, ensuring better product reliability in real-world conditions.

Regulatory compliance: Many industries, including automotive, aerospace, and consumer electronics, require adherence to IEC60068 standards as part of regulatory compliance. Conducting humidity tests is essential for meeting these requirements.

Quality control and improvement: The humidity test helps manufacturers identify potential issues during the design and manufacturing phases, enabling them to implement necessary quality control measures and make improvements in product design.

The IEC60068 humidity test finds applications in various industries, including electronics, telecommunications, healthcare, automotive, and aerospace. It helps assess products' ability to withstand humid environments, preventing failures and malfunctions that could lead to safety hazards or financial losses.
