Standardization is the driving factor in EMC business. EMC requirements are specified in a vast number of standard documents issued by various committees and organizations. The documents are organized as follows: Basic standards: Describe the phenomenon, characterize the test equipment and give guidance how tests shall be performed and documented. Basic standards like IEC x form the lowest level in standard's hierarchy. Generic standards: Specify test levels for a certain range of application, referring to the Basic Standards for general information. Generic standards give minimum requirements, e.

The European equivalent of the standard is called EN The current version of the IEC standard is the second edition dated The publication describes requirements, levels and test methods to achieve immunity compliance of an electronic product. The purpose is to create a reproducible ground for product compliance and the standard defines: ranges, levels, test equipment, setups, procedures, calibrations, generator waveforms and general uncertainties.
The intention is not to define product specific tests but instead establish a basic common reference. Product specific tests are instead defined in standards such as EN for alarm systems, EN for railway applications or IEC for medical equipment. The product, or equipment under test EUT , is seen from an operators point of view during test.
The EUT is therefore in its operational mode and testing does not include storage or transportation conditions. The EUT is subjected to three types of discharge. Direct contact discharge is preferred ether directly to the EUT or indirectly through vertical or horizontal coupling planes.
Air discharge is used where direct contact cannot be applied. Note: This table is simplified for the purpose of giving a quick overview. It does not contain the same level of detail as the official IEC The transient duration is not specified but for waveform verification currents should be measured in 30 ns and 60 ns for each of the test levels.
