This Technical Report is applicable to any non-exempt military equipment. This Technical Report does not affect the requirements to meet military standards. This Technical Report only covers aspects related to EMC as covered by the EMC Directive 2004/108/EC and other directives that address EMC. In this respect there is no distinction between civilian and defence equipment. For the purpose of this Technical Report the term “military” is equivalent to the term “defence”. Annex B describes Article 346 and Annex C provides the associated EC Council List of items under Article 346 [12]. The definitions in EMC Directive 2004/108/EC of “apparatus” and “fixed installations” as applied to military equipment are considered and guidance is given on applicability with the use of flow diagrams. For apparatus, the use of military standards to demonstrate compliance with the EMC Directive by using various assessment methods that do not use harmonised standards and a “gap” analysis tool for comparison of military standard results with harmonised standards is presented. This Technical Report also covers fixed installations using military equipment, and their impact on neighbouring environments. The conformity assessment procedures of EMC Directive 2004/108/EC have been reviewed and guidance given on the applicability and contents of detailed technical EMC assessment. Annex J includes some case studies to help clarify the extent and use of this Technical Report.

This Technical Report applies to emission measurements of radiated electromagnetic fields in Fully Anechoic Rooms (FAR) in the frequency range from 30 MHz to 18 GHz. This Technical Report covers the frequency range from 30 MHz – 1 000 MHz. The frequency range above 1 GHz is under consideration, due to the absence of practical experience. This Technical Report describes the validation procedure for the Fully Anechoic Room for radiated emission tests and the procedures to carry out the tests (e.g. test set up, EUT position, cable layout and termination, test procedures). Recommendations for the relation between FAR emission limits and common Open Area Test Site (OATS) emission limits given in standards such as EN 55011 and EN 55022 are given in Annex B. This FAR emission method may be chosen by product committees as an alternative method to emission measurement on an Open Area Test Site (OATS) as described in CISPR 16 series. In such cases, the product committee should also define the appropriate limits. Typical measurement uncertainty values for FARs and OATS are given in Annex C.

This Technical Report applies to shielded enclosures used for EMC testing which are to be validated according to the EN 50147 series of standards and the corresponding international standards. The object of this report is to give guidance to the selection of the shielding materials and components. The frequency range for this document is 10 kHz to 40 GHz.

This document was prepared to give users general advices on filtering solutions adopted in shielded enclosures. It is mainly a collection of hints derived from practical experience. This document is coordinated with EN 50147-1 and EN 50417-2. The document covers the frequency range DC to 40 GHz. The range above 40 GHz and up to 400 GHz is under consideration.

This standard deals with the electromagnetic emission (radio frequency protection) of machine tools, excluding electro discharge machines (EDM), designed exclusively for industrial and similar purposes that use electricity, the rated voltage of the machine tool not exceeding 1 000 V AC or 1 500 V DC between lines. Machine tools may incorporate motors, heating elements or their combination, may contain electric or electronic circuitry, and may be powered by the mains, or any other electrical power source. This standard does not cover fixed installations as defined in the Guide to the Application of Directive 89/336/EEC, published by the European Commission. Emission requirements in the frequency range 9 kHz to 400 GHz are covered. No measurements need to be performed at frequencies where no requirements are specified.

This standard deals with the electromagnetic immunity of machine tools designed exclusively for industrial and similar purposes that use electricity, the rated voltage of the machine tool not exceeding 1 000 V a.c. or 1 500 V d.c. between lines. Machine tools may incorporate motors, heating ele¬ments or their combination, may contain electric or electronic circuitry, and may be powered by the mains, or any other electrical power source. This immunity standard may also be used for assessment of equipment used in other environments, which require less stringent immunity levels (residential, light industry…) than the industrial environment. This standard is not intended for the EMC conformity assessment of modules to be placed on the market separately. This standard is not intended for complying with Machinery Directive 98/37/EC. Hence safety considerations are not covered by this standard. This standard does not cover fixed installations as defined in the Guide to the Application of Directive 89/336/EEC, published by the European Commission. This standard does not apply to apparatus intended to be used in locations where special electromagnetic conditions prevail, such as the pres¬ence of high electromagnetic fields (e.g. in the vi¬cinity of a broadcast transmitting station) or where high pulses occur on the power network (e.g. in a power generator station). In these instances special mitigation measures may have to be employed. Immunity requirements in the frequency range 0 Hz to 400 GHz are covered. No measurements need to be performed at frequencies where no requirements are specified.

This standard applies to measurements of shielding attenuation of shielded enclosures (chambers, rooms) in the frequency range 9 kHz - 40 GHz. The object of this standard is to establish a common measurement procedure for validating the shielding effectiveness of a shielded enclosure.

There are many different test sites and facilities that have been constructed to make radiated emission measurements at frequencies above 30 MHz according to CISPR 16-1. Most are protected from the weather and the adverse effects of the radio frequency ambient noise. These include all weather covered open area test sites and absorber lined shielded enclosures. Whenever construction material encloses a test site, there exists the possibility that the result of a single normalized site attenuation measurement as specified in subclause 16.6 of CISPR 16-1 is not adequate to show such alternate site suitability NOTE: Radiated emission sources located near dielectric interfaces have been shown to have variations in current distribution that can affect the radiated properties of the source at that location. When the EUT can be located near these interfaces, additional site attenuation measurements are required. This standard specifies requirements for alterneative test sites regarding site attenuation. As long as the document CISPR/A(CO)63 is not published as part of CISPR 16, this standard shall be used for test site qualification.

Corrigendum to EN issued November 2004 * Superseded by EN 61000-6-3:2007

This guideline deals with the application of absorber-lined enclosures for radiated-emission tests according to CISPR 16 [1 , CISPR 11 [2 , CISPR 22 [3 and EN 50147-2 [4 in the frequency range of 30-1000 MHz. Standard site acceptability criteria based on normalized site attenuation (NSA) measurements are given in (1, 4). The chamber factor concept shall provide a method for more detailed evaluations of the performance characteristics of enclosures. Measured chamber factor data can, furthermore, be used to correlate test results from equipment under test (EUT) to open site results. Whereas NSA evaluates chamber performance with respect to theoretically calculated reference values, chamber factors are derived from comparative measurements between an enclosure and a good reference site. If the measured site attenuation exceeds the "4 dB" limit only in the frequency range of 30-200 MHz and by not more than 12 dB, then the methods described in this report may be applied. For equipment that is no larger than half a wavelength (including cables) the enclosure can then be used at the expense of higher test uncertainty in the lower frequency range.

The scope of the Generic Standards specifies the applicability of the standards to products intended for use in a given environment. As these Generic Standards may be applied to all relevant electrical and electronic equipment and systems, electromagnetic phenomena in the broad frequency range 0 Hz to 400 GHz have been considered to ensure electromagnetic compatibility in most situations. From a practical point of view and from the probability of occurrence of disturbances, the emphasis has been given to frequencies up to 1 GHz for both immunity and emission. Because of lack of availability of approved standards, tests have been limited, for example up to 1 GHz in case of emission and 5OO MHz for immunity. An extension of these frequency ranges is foreseen when basic standards are revised. The emission limits are required to restrict electromagnetic disturbances to maximum permissible levels, for these specific environments in order to avoid interference in other equipment or systems. The emission limits in the radio-frequency range are to protect the effective use of the radio-frequency spectrum. All revisions of existing and drafting of future product standards shall take this into account.

This guide describes analysis methods of disturbance emission to be applied in situ for identification of the disturbance source and resolution of complaint. Where applicable, the methods rely on already published documents either in CENELEC or in IEC. It is not intended to be used for type testing or any kind of conformity assessment. Dealing with effects on living matter is excluded from this document. The frequency range of interest is from d.c. to 400 GHz. This document applies for analysing an interference complaint. It provides method for identification and characterisation in situ of the source(s) of interference. It proposes procedures to discriminate different kind of sources. Reference in situ measurement distances are defined. It allows comparison of the results and of technical characteristics of the interfered equipment with existing relevant standards. The result of the comparison is intended to help in the resolution of the complaint. It is meant for verifying the emissions from fixed installations whatever equipment they contain, and whatever have been the type tests of these equipment. It may be used to describe the coupling path for interference between the victim and the source, and to compare the measurement results with the limits from the adequate standard, at a specific location and in a given frequency band.
