Categories of EMC publications

With this approach in mind, the IEC in principle prepares EMC documents that fall into one of two categories.
The first, comprising what are known as basic EMC publications, is 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.
Because of the broad-ranging nature of basic EMC publications, they are generally but not exclusively developed by IEC technical committees that have what are called horizontal functions. 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.
The second category comprises International Standards that apply to products. These may be either generic EMC Standards or specific EMC product Standards, which as a rule apply appropriate publications from the basic series. Many product standards encompass a family of similar products and these publications are referred to as product family Standards.
The basic and generic Standards represent a broad approach. The IEC has developed them as efficient building blocks for technical committees to use in preparing appropriate product Standards.
Development of specific EMC product Standards is almost exclusively allocated to the numerous IEC technical committees dealing with individual products or families of products, usually referred to as product committees. This is because these groups know best the functional requirements for and operating conditions of the particular components, subsystems and systems they are standardizing.
