Technical committeeTypeAcronymIEC 61000-2-12CommitteePublished year2003KeywordsDescription
This part of IEC 61000 is concerned with conducted disturbances in the frequency range from 0 kHz to 9 kHz, with an extension up to 148,5 kHz specifically for mains signalling systems. Compatibility levels are specified for electromagnetic disturbances of the types which can be expected in public medium voltage power supply systems, for guidance in: a) the limits to be set for disturbance emission into public power supply systems (including the planning levels defined in 3.1.5); b) the immunity limits to be set by product committees and others for the equipment exposed to the conducted disturbances present in public power supply systems. The disturbance phenomena considered are: voltage fluctuations and flicker, harmonics up to and including order 50, inter-harmonics up to the 50th harmonic, voltage distortions at higher frequencies (above 50th harmonic), voltage dips and short supply interruptions, voltage unbalance, transient overvoltages, power frequency variation, d.c. components, mains signalling. The medium-voltage systems covered by this standard are public distribution systems supplying either: a) private installations in which equipment is connected directly or through transformers, or b) substations feeding public low-voltage distribution systems.

Technical committeeTypeAcronymIEC 61000-2-10CommitteePublished year1998KeywordsDescription
Defines the high-altitude electromagnetic pulse (HEMP) conducted environment that is one of the consequences of a high-altitude nuclear explosion. Establishes a common reference for this environment in order to select realistic stresses to apply to victim equipment for evaluating their performance. Presents the conducted HEMP environment induced on metallic lines, such as cables or power lines, external and internal to installations, and external antennas.

Technical committeeTypeAcronymCISPR TR 31CommitteePublished year2012KeywordsDescription
CISPR/TR 31:2012 covers the rationale behind the actual database covering the characteristics of radio services. The objective of the database is to register those characteristics which are relevant for derivation and specification of limits for disturbance emissions from electric and/or electronic equipment, systems and installations. Committees responsible for generic and/or product emission EMC standards should use this information together with CISPR 23. This second edition includes the replacement of CISPR 23 as reference standard for the determination of limits by CISPR 16-4-4:2007 on "model for the calculation of limits for the protection of radio services".

CISPR/TR 30-1:2012(E), which is a technical report, details, with the aid of reference luminaires, an independent method by which the radio disturbance characteristics of electronic control gear for fluorescent lamp luminaires with protection classes I and/or II may be compared against the requirements of CISPR 15. This technical report covers electronic control gear for double-capped fluorescent lamps fitted with G5 or G13 lamp caps and to single-capped fluorescent lamps fitted with lamp caps: 2GX7, 2G8, 2G10, 2G11, 2GX13, G23, GX23, G24q, GX24q, GR8, and GR10q. It is specifically applicable for equipment to be connected to 230 V - 50 Hz mains power networks. For other power systems, modifications may be necessary. This first edition of CISPR/TR 30-1 cancels and replaces the first edition of CISPR/TR 30 published in 2001. It is a technical revision which includes the following significant technical changes with respect to the previous edition:
- minor correction of wiring distances of reference luminaire in Figure A.1;
- addition of reference luminaires for electronic control gear with output terminals on both ends;
- addition of reference luminaires for electronic control gear for circular-shaped fluorescent lamps; and
- introduction of control gear marking indicating suitability for application in protection class I and/or class II luminaires. -

CISPR TR 18-2:2017 RLV contains both the official IEC International Standard and its Redline version. The Redline version is available in English only and provides you with a quick and easy way to compare all the changes between the official IEC Standard and its previous edition.
CISPR TR 18-2:2017 which is a Technical Report, applies to radio noise from overhead power lines and high-voltage equipment which may cause interference to radio reception. The frequency range covered by this publication is 0,15 MHz to 3 GHz. A general procedure for establishing the limits of the radio noise field from the power lines and equipment is recommended, together with typical values as examples, and methods of measurement. The clause on limits concentrates on the low frequency and medium frequency bands and it is only in these bands where ample evidence, based on established practice, is available. No examples of limits to protect radio reception in the frequency band 30 MHz to 3 GHz have been given, as measuring methods and certain other aspects of the problems in this band have not yet been fully resolved. Site measurements and service experience have shown that levels of noise from power lines at frequencies higher than 300 MHz in normal operation are so low that interference is unlikely to be caused to television reception. The values of limits given as examples are calculated to provide a reasonable degree of protection to the reception of broadcasting at the boundary of the recognized service areas of the appropriate transmitters in the radio frequency bands used for a.m. radio broadcasting, in the least favourable conditions likely to be generally encountered. These limits are intended to provide guidance at the planning stage of the line and national standards or other specifications against which the performance of the line may be checked after construction and during its useful life. The measuring apparatus and methods used for checking compliance with limits should comply with the respective CISPR specifications, as e.g. the basic standards series CISPR 16, see [1]. This third edition of CISPR TR 18-2 is adapted to the modern structure and content of technical reports issued by IEC. The second edition of CISPR TR 18-2 underwent thorough edition and adaptation to modern terminology. This third edition now also covers an adequate method of measurement for radiated disturbances from HV overhead power lines and substations in the range 300 MHz to 3 GHz, since gap-type discharges can be a potential noise source disturbing modern digital radio communication.
