IEC 60529 describes a system for classifying the degrees of protection provided by the enclosures of electrical equipment. Whilst this system is suitable for use with most types of electrical equipment, it should not be assumed that all the listed degrees of protection are applicable to a particular type of equipment. The manufacturer of the equipment should be consulted to determine the degrees o...
In order to achieve reproducibility, temperature tests must be designed in such a way that the highest or lowest temperature reached at a certain point in the high and low temperature test chamber is the same, regardless of the laboratory in which the test is conducted. For test designs with a shorter duration compared to the time required for the test sample to reach temperature stability, the fo...
Introduction Electromagnetic compatibility (EMC) is significant in the field of industrial automation, where continuous production processes are essential for success. Numerous electronic devices coexisting in industrial settings may cause electromagnetic interference (EMI) and interfere with the efficient operation of automated systems. In order to properly evaluate and remedy EMI concerns in ind...
