2 EMC Publications Industry uses standards to help create products and services. In this sense, standards help industry to save time and money, thus creating efficiency. Standards serve other purposes as well, but their main use is as a tool for industry. Given this, to make a standard more valuable, it needs to fit into a global, coherent context. Horizontal publications from the IEC (see definitions below) can cover a variety of subjects and they apply to a broad range of product committees. In general, they deal with fundamental principles, concepts, terminology or technical characteristics that are relevant to a number of technical committees. The goal of a horizontal publication is to ensure the consistency of IEC publications in areas common to a number of technical committees by avoiding duplication of work and contradictory requirements. The focus of this brochure is electromagnetic compatibility (EMC) publications.* Experts who prepare IEC standards relating to products and systems are professional and * Please note: there is another similar IEC brochure dealing with safety. 2

3 conscientious, working to ensure the quality, accuracy and completeness of their work. When preparing standards for equipment or systems, experts need to know which EMC aspects need to be included in their work. Often, they either need to refer to the correct IEC standard in its entirety, or refer to the appropriate sections, paragraphs and clauses in the text they are preparing. As a useful tool, this brochure will help technical committee and subcommittee experts to save time by providing a handy guide listing all IEC EMC publications. If they cannot find the information they need in existing EMC Publications, technical committees can ask for assistance from, and work with, the relevant horizontal group to develop what they need. EMC describes the ability of electronic and electrical systems or components to work correctly when they are close together. In practice this means that the electromagnetic disturbances from each item of equipment must be limited and also that each item must have an adequate level of immunity to the disturbances in its environment. Because of the broad-ranging nature of Basic EMC publications, it is generally IEC technical committees with horizontal functions that develop them. For EMC, these are Technical Committee 77 (Electromagnetic compatibility), and CISPR the International Special Committee on Radio Interference that is also part of the IEC. EMC standards fall into three classes 1. Basic EMC publications are intended as a comprehensive set of background reference standards and technical reports that cover all general aspects of the problem. They deal with matters such as description of the EM environment, measurement methods, testing techniques and the like. 2. The second category comprises standards that apply to products for use in a particular environment. These are known as Generic EMC standards. They apply appropriate publications from the Basic series to a specified environment. 3. EMC Product standards may apply to particular products, such as electricity meters and printed circuit boards. They can also apply to a group of products that have common 3

4 general characteristics, such as medical devices, IT equipment (ITE) and low-voltage household equipment. In the latter case, the publications are known as EMC Product Family standards. A horizontal committee in thorough consultation with all product committees concerned develops Basic Safety Publications. Procedures are given in a standing document the current version is Administrative Circular 29/2002 and on the IEC website, where up-to-date lists of horizontal publications can also be found. The Standardization Management Board permanently oversees the process and SMB members and National Committees have specific responsibilities to aid the committees concerned The IEC Advisory Committee on Electromagnetic Compatibility (ACEC) maintains a list of all the main product families covered by IEC EMC standards. They can be found in the EMC Zone on the IEC s website. For reasons of certification, the IEC distinguishes four categories of products for EMC standardization purposes: Components These are items that do not themselves have a final function but which are intended for inclusion in an apparatus, such as capacitors, transformers and circuit boards. 4

5 5 Apparatus These are single finished products with a direct function and intended for final use, such as domestic appliances, medical equipment, tools and circuit-breakers. Systems These are combinations of apparatus and/or components constituting a single functional unit and intended to be installed and operated to perform a specific task. A good example is a computer system comprising a CPU, monitor, keyboard, mouse, printer, etc. Installations These are combinations of components, apparatus and systems assembled or erected in a given area, such as industrial plants, electricity substations or telecontrol systems for large areas. Definitions* Publication: a published IEC document that is a standard, a technical report, a technical specification or a guide. Basic publication (also referred to as a horizontal publication): a publication prepared by a technical committee with a horizontal function, containing general provisions for one particular subject. Horizontal function: treatment of subjects such as fundamental principles, concepts, terminology or technical characteristics, relevant to a number of technical committees (a technical committee with a horizontal function may prepare horizontal publications). Horizontal technical committee: a technical committee that prepares exclusively basic publications. Product committee: a technical committee having a scope which covers a specific product or group of related products. Product standard: a publication prepared by a product committee, related to its scope. *Note: when preparing IEC publications, experts should refer to the definitions given in IEC Guides 107 and 108.

6 Basic EMC standard: specifies the general conditions or rules necessary for achieving electromagnetic compatibility. Serves also as a building block for the IEC technical committees that develop EMC Product standards. Generic EMC standard: for products operating in a particular EMC environment but for which no specific EMC standards yet exist. They are in effect general and somewhat simplified EMC Product standards.
