      IEC 60068-2-78 is an international standard that specifies the method of constant humidity cabinet testing for evaluating the adaptability of electrical and electronic products, components or materials in a high Humidity environment. The standard is suitable for small and large equipment, including heat dissipation and non-heat dissipation samples. The test determines the change in the performance of the sample over a specified time by simulating a constant temperature and high humidity environment without condensation. The standard also specifies the requirements of the test chamber, the test procedure, the severity rating and the information that should be included in the test report.
