The surge immunity test is applied in China both to equipment and to the surge protective devices installed upstream of it, and the two are governed by separate Chinese standards that are read together when an installation is designed. This part of the Chinese EMC test series provides the test for the equipment, while the surge protective device itself is covered by the dedicated Chinese standard for low voltage protective devices; a designer working to a Chinese specification therefore needs both documents, and a test report that covers only the equipment does not establish that the installation will be protected. The requirement reaches a manufacturer through the Chinese product standards for information technology equipment, household appliances and telecommunications equipment, where the level is selected according to the exposure of the installation. The Chinese text follows the international document in the generator and the coupling networks.
