List of common EMC test standards explained

The following list outlines a number of electromagnetic compatibility (EMC) standards which are known at the time of writing to be either available or have been made available for public comment. These standards attempt to standardize product EMC performance, with respect to conducted or radiated radio interference from electrical or electronic equipment, imposition of other types of disturbance on the mains supply by such equipment, and the sensitivity of such equipment to received interference.

The legal status of these standards varies according to the jurisdiction. Standards called up by the European Union's EMC Directive effectively have the force of law in the EU.

CISPR standards

CISPR https://www.iec.ch/dyn/www/f?p=103:7:::::FSP_ORG_ID:1298 is the acronym of Comité International Spécial des Perturbations Radio,^[1] or the International Special Committee for Radio Protection of IEC.CISPR Standards aim to the protection of radio reception in the range 9 kHz to 400 GHz from interference caused by operation of electrical or electronic appliances and systems in the electromagnetic environment.CISPR standards cover product emission and immunity requirements as well as defining test methods and equipment.

CISPR standards are divided into the following categories:https://assets.iec.ch/public/miscfiles/other/CISPR%20Guide%202021.pdf

They give the general and fundamental conditions or rules for the assessment of EMC and related performance of all products, systems or installations, and serve as reference documents for CISPR Generic and Product (Family) Standards. Basic Standards are general and hence are not dedicated to specific product families or products; they relate to general information, to the disturbing phenomena and to the measurement or testing techniques. They do not contain any prescribed limits or any product/system related performance specifications.
