IEC:2001 5 ELECTROMAGNETIC COMPATIBILITY (EMC) Part 5-7: Installation and mitigation guidelines Degrees of protection provided by enclosures against electromagnetic disturbances (EM code) 1 Scope This part of IEC 61000 describes performan
33、ce requirements, test methods and classification procedures for degrees of protection provided by empty enclosures against electromagnetic disturbances for frequencies between 10 kHz and 40 GHz. The shielding performance is to be measured prior to the installation of internal electrical and/or elect
34、ronic equipment and components. This shielding protection is measured for the purpose of demonstrating that the enclosure provides adequate shielding of electromagnetic energy to support acceptable performance of the complete assembled units when tested to applicable IEC standards. However, it shoul
35、d be noted that satisfactory performance of an empty enclosure does not necessarily ensure that the completed units will pass all EMC performance test standards for the operating equipment (see discussion in annex A). The purpose of this standard is to provide a repeatable means for evaluating the e
36、lectromagnetic shielding performance of empty mechanical enclosures, including cabinets and subracks, and to specify a marking code to allow a manufacturer to select an enclosure with a known capability for attenuating electromagnetic fields. The requirements for immunity to various types of electro
37、magnetic disturbances, including lightning and high-altitude electro- magnetic pulse (HEMP) will need to be considered by manufacturers when determining the need for application of this standard for specific equipment and applications, and for the specific enclosure shielding requirements which are
38、necessary as a function of frequency. The adoption of the classification system in this standard will, whenever possible, promote uniformity in methods of describing the protection against electromagnetic stresses provided by the enclosure. This includes protection of equipment inside the enclosure
39、from external electromagnetic stresses, as well as protection of external equipment from internally generated electromagnetic stresses. Technical Committees responsible for enclosures may decide on the extent and manner in which the classification defined in this standard is used in their standards
40、and to define “enclosure” as it applies to their equipment. However, the tests and performance categories must not differ from those specified in this standard. An informative guide for the details to be specified in relevant enclosure product standards is given in annex B. Page 5 EN 6100057:2001 08

However, parties to agreements based on this part of IEC 61000 are encouraged to investigate the possibility of applying the most recent editions of the normative documents indicated below. For un

46、IEC series define requirements for construction and immunity testing of electrical and electronic equipment which shall withstand the stresses produced by electromagnetic disturbances, including fast electrical transients and electrostatic discharge (ESD). In addition, there are similar requirements
47、 for testing to verify immunity to high-altitude electromagnetic pulses (HEMP). There are also existing standards for these enclosures for other effects, primarily IEC 60529. However, manufacturers of this electrical and electronic equipment need to either construct or procure enclosures for this eq
48、uipment prior to the electromagnetic disturbance immunity testing noted in the previous paragraph. With experience the manufacturers will be able to determine the particular levels of electromagnetic shielding effectiveness which are sufficient to permit their finished product to pass the required E
49、MC immunity and emissions tests. Shielding Effectiveness (SE) is a broad term describing the ability of an EM shield to reduce or attenuate external (or internally produced) electromagnetic fields and external (or internal) surface currents before they reach the interior (exterior) of the shield. Typically, the shield encloses sensitive electronic equipment that must be protected from exterior electromagnetic disturbances. However, shields are also used to reduce electromagn
