EMC is electromagnetic compatibility, is the English word Electro Magnetic Compatibility abbreviation, refers to the equipment or system in the normal operation of the process of the environment where the electromagnetic interference can not exceed a certain limit, at the same time appliances in the environment where the existence of electromagnetic interference with a certain degree of immunity, that is, electromagnetic sensitivity.
International most of the electrical components or devices for EMC certification, the purpose is to ensure that electrical components or devices in the electromagnetic environment can have the ability to work normally.

EMC certification process
1, randomly selected samples in the sampling matrix, where different samples are used for testing and corporate retention for inspection.
2, from the samples used for testing in a randomly selected EMC test, the test results than the certification implementation standards specified in the limit value of 2dB to determine the tightening.
3, if a single sample of the measurement results to meet the requirements than the certification standards for the implementation of the limit value of 2dB more stringent, it is determined that the sample test passes.
