CISPR 16-1-4: Ancillary equipment – Radiated disturbances

CISPR 11: Industrial, scientific and medical equipment - Radio-frequency disturbance characteristics - Limits and methods of measurement. CISPR 11 applies to industrial, scientific and medical electrical equipment operating in the frequency range 0 Hz to 400 GHz and to domestic and similar appliances designed to generate and/or use locally radio-frequency energy. This standard covers emission requirements related to radio-frequency (RF) disturbances in the frequency range of 9 kHz to 400 GHz. Measurements need only be performed in frequency ranges where limits are specified in Clause 6. For ISM RF applications in the meaning of the definition found in the ITU Radio Regulations (see Definition 3.13), this standard covers emission requirements related to radio-frequency disturbances in the frequency range of 9 kHz to 18 GHz. Requirements for ISM RF lighting equipment and UV irradiators operating at frequencies within the ISM frequency bands defined by the ITU Radio Regulations are contained in this standard. Equipment covered by other CISPR product and product family emission standards are excluded from the scope of this standard. This sixth edition cancels and replaces the fifth edition published in 2009 and its Amendment 1 published in 2010. It constitutes a technical revision. It introduces and permits type testing on components of power electronic equipment, systems and installations. Its emission limits apply now to low voltage (LV) a.c. and d.c. power ports, irrespective of the direction of power transmission. Several limits were adapted to the practical test conditions found at test sites. They are also applicable now to power electronic ISM RF equipment used for wireless power transfer (WPT), for instant power supply and charging purposes. The limits in the range 1 GHz to 18 GHz apply now to CW-type disturbances and to fluctuating disturbances in a similar, uniform and technology-neutral way. For these measurements, two alternative methods of measurement

CISPR 12 is equivalent to the SAE J 551-2 standard for the following: vehicles, boats, and internal combustion engine-driven devices - radio disturbance characteristics - limits and methods of measurement. Test setup according to CISPR12 typically is as follows: a monopole is used for the range 150 KHz to 30 MHz only vertical polarization measurements are made for 30 MHz to 200 MHz, a biconical antenna is used the log-periodic is used for the range 200 MHz-1000 MHz a biconical antenna is used, the log-periodic is used for the range 200 MHz-10000 MHz tuned dipoles can be used for the entire range. For 10 m testing, the antenna is 10 meters from the outer skin of the vehicle and in line with engine midpoint. Both sides of the vehicle are tested. For 3 m testing antenna is placed at 1.8 m both polarizations are measured. According to CISPR 12, the chamber must be correlated to OATS. An NSA measurement showing a small deviation should demonstrate that development. This standard applies to the emission of electromagnetic energy which may cause interference to radio reception and which is emitted from a) vehicles propelled by an internal combustion engine, electrical means or both (see 3.1); b) boats propelled by an internal combustion engine, electrical means or both (see 3.2). Boats are to be tested in the same manner as vehicles except where they have unique characteristics as explicitly stated in this standard c) devices equipped with internal combustion engines (see 3.3). See Annex G for a flow chart to help determine the applicability of CISPR 12. This standard does not apply to aircraft, traction systems (railway, tramway, and electric trolley bus), or incomplete vehicles. In the case of a dual-mode trolley bus (e.g. propelled by power from either a.c./d.c. mains or an internal combustion engine), the internal combustion propulsion system must be included, but the AC/DC mains portion of the vehicle propulsion system is

CISPR 14-1 specifies the requirements that apply to the emission of radio-frequency disturbances in the frequency range 9 kHz to 400 GHz from appliances, electric tools, and similar apparatus, whether powered by AC or DC (including a battery). Also included in the scope of CISPR 14-1 are separate parts of the above-mentioned equipment such as motors and switching devices (e.g. power or protective relays); however, no emission requirements apply to such separate parts, unless otherwise stated in this standard. The limits in this standard have been determined on a probabilistic basis, to keep the suppression of disturbances economically feasible while still achieving adequate radio protection. In exceptional cases, radio frequency interference may occur, despite compliance with the limits. In such a case, additional provisions may be required. The effects of electromagnetic phenomena relating to the safety of the apparatus are excluded from the scope of this standard.

CISPR 14-2 deals with the electromagnetic immunity of appliances and similar apparatus for household and similar purposes that use electricity, as well as electric toys and electric tools, the rated voltage of the apparatus being not more than 250 V for single-phase apparatus to be connected to phase and neutral, and 480 V for other apparatus. Apparatus may incorporate motors, heating elements or their combination may contain electric or electronic circuitry, and may be powered by the mains, by transformer, by batteries, or by any other electrical power source. Apparatus not intended for household use, but which nevertheless may require the immunity level, such as apparatus intended to be used by laymen in shops, in light industry, and on farms, are within the scope of this standard, as far as they are included in CISPR 14-1. In addition, the following are also included in the scope of this standard: Microwave ovens for domestic use and catering Cooking hobs and cooking ovens, heated by means of RF energy Single- and multiple-zone induction cooking appliances Appliances for personal care equipped with radiators in the range from UV to IR, inclusive (this includes visible light) Power supplies and battery chargers provided with or intended for apparatus within the scope of this standard For ESD tests on contacts of plugs and sockets the note ("The 4 kV contact discharge shall be applied to conductive accessible parts. Metallic contacts, such as in battery compartments or in socket outlets, are excluded from this requirement") saying that no test on contacts is necessary has been removed. The IEC 61000-4-2 includes a detailed description of how to deal with ESD on contacts and other surfaces. Also, discharge on HCP and VCP is required by the basic standard IEC 61000-4-2.

CISPR 16-1-1 specifies the characteristics and performance of equipment for the measurement of radio disturbance in the frequency range from 9 kHz to 18 GHz. Also, CISPR 16-1-1 provides requirements for specialized equipment for discontinuous disturbance measurements.  In accordance with IEC Guide 107, CISPR 16-1-1 is a basic electromagnetic compatibility (EMC) standard for use by product committees of the IEC. As stated in Guide 107, product committees are responsible for determining the applicability of a basic EMC standard. CISPR and its subcommittee are prepared to co-operate with product committees in the evaluation of the value of particular EMC tests for specific products. The specifications in this document apply to electromagnetic interference (EMI) receivers and spectrum analyzers. The term “measuring receiver” used in this document refers to both EMI receivers and spectrum analyzers (see also 3.7).

Buy Standard This part of CISPR 16 is designated a basic standard, which specifies the characteristics and calibration of the absorbing clamp for the measurement of radio disturbance power in the frequency range 30 MHz to 1 GHz. The second edition cancels and replaces the first edition published in 2003. It constitutes a technical revision. In this edition a more detailed calibration method for the absorbing clamp is specified. Furthermore, new alternative calibration methods are introduced which are more practicable than the one which was specified previously. Additional parameters to describe the absorbing clamp are defined, like the decoupling factor for the broadband absorber (DF) and the decoupling factor for the current transformer (DR), along with their validation methods. A procedure for the validation of the absorbing clamp test site (ACTS) is also included in the document.

CISPR 16-2 specifies the methods of measurement of radiated disturbance phenomena in the frequency range of 9 kHz to 18 GHz. This standard also specifies methods of measurement of conducted disturbance phenomena in the frequency range from 9 kHz to 30 MHz. With a CDNE, the frequency range is 9 kHz to 300 Hz. The aspects of measurement uncertainty are specified in CISPR 16-4-1 and CISPR 16-4-2. CISPR 16-2 has the status of a basic EMC publication in accordance with IEC Guide 107, "Electromagnetic compatibility - Guide to the drafting of electromagnetic compatibility publications". These methods are further divided into the following categories: conducted disturbance measurements, measurement of disturbance power, radiated disturbance measurements, and immunity measurements. Advanced Test Equipment Rentals provides a variety of equipment for performing immunity tests in accordance with CISPR 16-2 or otherwise. Check out related equipment here.

WITHDRAWN: Replaced by CISPR 32 View CISPR 32 CISPR 22: Information technology equipment - Radio disturbance characteristics - Limits and methods of measurement. CISPR 22 applies to information technology equipment (ITE). Procedures are given for the measurement of the levels of spurious signals generated by the ITE and limits are specified for the frequency range 9 kHz to 400 GHz for both class A and class B equipment. No measurements need be performed at frequencies where no limits are specified. The intention of this publication is to establish uniform requirements for the radio disturbance level of the equipment contained in the scope, to fix limits of disturbance, to describe methods of measurement and to standardize operating conditions and interpretation of results. This sixth edition of CISPR 22 cancels and replaces the fifth edition published in 2005, its Amendment 1 (2005) and Amendment 2 (2006). This edition constitutes a minor revision. CISPR 22:2008 is also available as IEC Standards+ CISPR 22:2008 which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

CISPR 24 is a test standard for the immunity testing of information technology equipment (ITE). The standard covers ITE which operate within the frequency range of 0 Hz to 400 GHz. CISPR 24 focuses on the simulation of continuous, transient conducted and radiated disturbances, including the following tests: surge, magnetic field, power interruptions, electrostatic discharge (ESD), radio frequency interference (RFI) and electrical fast transients (EFT). This standard stipulates the minimum level of intrinsic immunity ITE must possess to pass EMC testing and operate as designed to in the real world. The requirements apply to ITE on a port by port approach; CISPR defines ports as falling under the category of earth, signal, AC power, DC power or telecommunication ports. CISPR 24 is identical to EN 55024, its European Union counterpart. To achieve compliance with the European EMC Directive 2004/108/EC, however, ITE also need to be tested for spurious signal levels according to EN 55022 practices. Equipment power through AC mains may require power line harmonics and power line flicker testing as well. The term ITE is defined by CISPR 24/EN55024 as encompassing the following devices: Central processing units and peripherals (i.e. processor storage) Minicomputers Midrange computers Microcomputers Personal computers and peripheral units Special purpose systems (i.e. word processing) Communication devices used for transmission of data (i.e. modems) Input-output units (i.e. card readers) More On ESD Testing  

CISPR 25 controls the radio environment within the vehicle and was developed in response to the variety of radio receivers that can be installed and/or used in modern motor vehicles. The standard subcommittee holds the view that interference to on-board radio reception caused by equipment on the same vehicle is a quality, or customer satisfaction issue, rather than a matter for government regulation. CISPR 25 defines test methods for use by vehicle manufacturers and suppliers, to assist in the design of vehicles and components and ensure controlled levels of on-board radio frequency emissions. Vehicle test limits are provided for guidance and are based on a typical radio receiver using the antenna provided as part of the vehicle, or a test antenna if a unique antenna is not specified. The frequency bands that are defined do not apply to all regions or countries of the world. For economic reasons, the vehicle manufacturer must be free to identify what frequency bands are applicable in the countries in which a vehicle will be marketed and which radio services are likely to be used in that vehicle. CISPR 25 standard accomplishes the following: Establishes a test method for measuring the electromagnetic emissions from the electrical system of a vehicle; Sets limits for the electromagnetic emissions from the electrical system of a vehicle; Establishes a test method for testing on-board components and modules independent from the vehicle; Sets limits for electromagnetic emissions from components to prevent objectionable disturbance to on-board receivers CISPR 25 contains limits and procedures for the measurement of radio disturbances in the frequency range of 150 kHz to 2500 MHz. The standard applies to any electronic/electrical component intended for use in vehicles, trailers, and devices. Refer to International Telecommunications Union (ITU) publications for details of frequency allocations. The limits are intended to provide protection for

CISPR 32: Electromagnetic compatibility of multimedia equipment - Emission requirements. CISPR 32 is available as CISPR 32:2015 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition. CISPR 32:2015 applies to multimedia equipment (MME) as defined in 3.1.24 and having a rated r.m.s. AC or DC supply voltage not exceeding 600 V. This publication covers two classes of MME (Class A and Class B). The MME classes are specified in Clause 4. The objectives of this publication are: 1) to establish requirements which provide an adequate level of protection of the radio spectrum, allowing radio services to operate as intended in the frequency range 9 kHz to 400 GHz; 2) to specify procedures to ensure the reproducibility of measurement and the repeatability of results.
