CISPR
CISPR is the Comité international spécial des perturbations radioélectriques (official translation: International Special Committee on Radio Interference ). Its members come partly from the IEC (International Electrotechnical Commission) and from other interest groups. It was founded in 1934 .
Specialist groups
The CISPR consists of six active sub-groups that deal with the following topics:
- A - Radiation measurements and statistical methods
- B - Disruptions to industrial, scientific or medical equipment, power networks, high voltage equipment and transportation
- D - Malfunctions in motorized (electric and internal combustion) vehicles
- F - malfunctions in household appliances and lighting systems
- H - limits to protect radio stations
- I - Electromagnetic compatibility of IT equipment (e.g. computers), multimedia / hi-fi equipment and radio receivers
The CISPR publications deal with standardized interference measurement methods for electromagnetic interference. For example, they prescribe cable lengths, device configurations and grounding and shielding measures for interference measurements, so that the results remain comparable and reproducible. At the same time, immunity to foreign interference is discussed. In this way, companies can simply require their component suppliers to conform to a corresponding CISPR standard instead of having to make all measurements themselves (and having to develop their own standard).
Publications
To date, over 30 CISPR standards have been published. Some of the most famous are:
- CISPR 10 - Organization, Rules and Procedures of the CISPR. (1971)
- CISPR 11 - Industrial, Scientific and Medical (ISM) Radio-Frequency Equipment - Electromagnetic Disturbance Characteristics - Limits and Methods of Measurement.
- CISPR 12 - Vehicles, boats, and internal combustion engine driven devices -radio disturbance characteristics -limits and methods of measurement
- CISPR 13 - Sound and television broadcast receivers and associated equipment - Radio disturbance characteristics - Limits and methods of measurement
- CISPR 14 - Electromagnetic Compatibility - Requirements for Household Appliance, Electric Tools, and Similar Apparatus: 1) Emissions, 2) Immunity.
- CISPR 16 - Specification for radio disturbance and immunity measuring apparatus and methods
- CISPR 20 - Sound and television broadcast receivers and associated equipment - Immunity characteristics - Limits and methods of measurement
- CISPR 22 - Information Technology Equipment - Radio Disturbance Characteristics - Limits and Methods of Measurement.
- CISPR 25 - Radio disturbance characteristics for the protection of receivers used on board vehicles, boats, and on devices - Limits and methods of measurement.
Work is currently underway to merge the devices that can no longer be separated into IT and sound and television equipment in CISPR 32 - Electromagnetic compatibility (EMC) - Multimedia equipment - Radio disturbance characteristics - Limits and methods of measurement , and to dissolve CISPR 13 and 22 in the longer term .
Corresponding standards
Most of the CISPR standards have been incorporated into European standards and translated into European languages. The same applies to the standards from the USA . The basic standard part is contained in ANSI -C63 and the product standard part in CFR47 (Code of Federal Regulations) by the FCC .
