Within the European system the surge immunity test is unusual in that it is applied both to the equipment and to the protective components that shield it. The test is called up by the multimedia equipment standard, by the measurement and control equipment standard and by the generic standards, while the surge protective devices that are installed upstream are covered by their own product standard; a complete design therefore involves two separate conformity assessments on the same installation. The European edition of this part reproduces the international combination wave generator and the coupling networks for power and signal ports, and it is the document cited in the declaration of conformity when the manufacturer has chosen the harmonised route. Because lightning exposure and the surge withstand of the distribution network differ across Europe, the level selected for a product is normally justified in the technical file by reference to the installation class rather than simply taken from the preferred list.
