What is the IEC 60068 humidity test

The IEC 60068 humidity test, also known as the humidity conditioning test, is a widely used testing method in various industries to evaluate the effects of humidity on electronic, electrical, and other types of equipment. This test is conducted according to the guidelines set by the International Electrotechnical Commission (IEC), an international organization that develops and publishes standards for electrical and electronic technologies.

Understanding the purpose of the test

The primary purpose of the IEC 60068 humidity test is to assess the performance, reliability, and durability of equipment when exposed to different levels of humidity. The test helps manufacturers identify potential issues related to moisture, such as corrosion, fungal growth, and electrical faults. By subjecting the equipment to controlled humidity conditions, engineers can determine if it can withstand the intended environment or if modifications are required to enhance its resistance to humidity-related problems.

Test procedure and conditions

The IEC 60068 humidity test involves subjecting the equipment to specific temperature and humidity combinations for a predetermined period. The actual test conditions vary depending on the type of equipment being tested and the requirements specified by the manufacturer or relevant industry standards. The test typically includes cycles of exposure to high humidity levels, followed by recovery periods at lower humidity levels. The duration and number of cycles are determined by the specific test standard or the equipment's intended use. Various measurement instruments, such as hygrometers, are used to monitor and record the humidity levels accurately during the test.

Benefits and applications

The information obtained from the IEC 60068 humidity test allows manufacturers to improve product design, materials selection, and manufacturing processes to enhance the equipment's performance under humid conditions. It ensures product reliability and reduces the risk of failures caused by humidity-related factors in real-world applications. The humidity test is especially crucial for industries such as automotive, aerospace, telecommunications, and consumer electronics, where exposure to high humidity environments is common. Compliance with applicable standards enhances customer confidence and helps manufacturers meet regulatory requirements governing product safety and performance.
