Scope and object
This section of IEC 1000-2 is a technical report intended for guidance, not as a specification, for those who are in charge of writing immunity standards for an equipment or system. Its purpose is to classify electromagnetic environments and help improve the specification of the immunity requirements of an item containing electrical or electronic parts, and consequently obtain electromagnetic compatibility. It also gives basic guidance for the selection of immunity levels. The data are applicable to any equipment, subsystem or system making use of electromagnetic energy and operating in a specific location as defined by this report. The environment inside transportation equipment (vehicles, traction, ships, aircraft) is not described in this report, but their effect on the surrounding environment is included.
It should be noted that the immunity level requirements chosen for the items are not only inevitably bound to their environment, but also to the requirements of the applications (e.g. for reliability or safety purposes). That could lead to more stringent requirements than usual. These levels may also be established for more general purposes such as generic and product standards, taking into account statistical and economical aspects as well as common experiences in certain application fields.
