Types of Standards

Types of Standards

Basic standards describe the general and fundamental rules for meeting the requirements. Terminology, phenomena, compatibility levels, measurement, test techniques and classification of EM environments are so described within.

Generic standards refer to specific environments. They set minimal EMI levels which equipment in these environments must meet. Where no product standards exist then the generic standards are to be used. Generic standards describe household and industrial EMI environments.

Products standards are for specific products or product groups. These standards are coordinated with the generic standards.
In countries outside Europe other standards will be used, such as the FCC in the USA. Table 1 shows the main European standards.
