Information technology equipment - Immunity characteristics - Limits and methods of measurement

Defines the immunity test requirements for information technology equipment (ITE, as defined in CISPR 22) in relation to continuous and transient, conducted and radiated disturbances, including electrostatic discharges (ESD). Procedures are defined for the measurement of ITE and limits are specified which are developed for ITE and within the frequency range from 0 Hz to 400GHz.This publication establishes requirements which will provide an adequate level of intrinsic immunity so that the equipment will operate as intended in its environment. The test requirements are specified for each port considered.

Appareils de traitement de l'information - Caractéristiques d'immunité - Limites et méthodes de mesure

Définit les prescriptions concernant l'évaluation de l'immunité pour les appareils de traitement de l'information (ATI, tels que définis dans le CISPR 22) en matière de perturbations continues et permanentes, conduites et rayonnées, ce qui inclut les décharges électrostatiques (DES). Des procédures sont définies pour la mesure des ATI et des limites leur sont spécifiées dans la gamme des fréquences comprises entre 0 Hz et 400 GHz. Cette publication définit des prescriptions qui apportent un niveau approprié d'immunité intrinsèque de façon que l'appareil puisse fonctionner normalement dans son environnement. Les prescriptions sont spécifiées pour chaque accès considéré.

Oprema za informacijsko tehnologijo - Karakteristike odpornosti proti motnjam - Mejne vrednosti in merilne metode

Ta objava CISPR velja za opremo za informacijsko tehnologijo (ITE), kot je opredeljeno v CISPR 22. Cilj te objave je vzpostaviti zahteve, ki bodo zagotovile zadostno raven notranje odpornosti, da bo oprema delovala v svojem okolju, kot je predvideno. Objava opredeljuje zahteve za preskušanje odpornosti za opremo v njenem območju uporabe ob upoštevanju neprekinjenih in občasnih, vodenih in sevanih elektromagnetnih motenj, vključno z elektrostatičnimi razelektritvami (ESD). Opredeljeni so postopki za merjenje ITE in določene so mejne vrednosti, razvite za ITE, v frekvenčnem razponu od 0 Hz do 400 GHz. V izjemnih okoljskih pogojih se lahko zahtevajo posebni ukrepi za ublažitev. Zahvaljujoč zahtevam glede preskušanja in zmogljivosti, so nekateri preskusi določeni v opredeljenih frekvenčnih razponih ali pri izbranih frekvencah. Za opremo, ki izpolnjuje zahteve pri teh frekvencah, se šteje, da izpolnjuje zahteve v celotnem frekvenčnem razponu od 0 Hz do 400 GHz za elektromagnetne pojave. Preskusne zahteve so določene za vsak obravnavan vhod. OPOMBA 1 Varnostni vidiki niso zajeti v tej objavi. OPOMBA 2 V posebnih primerih bodo nastale situacije, kjer raven motnje lahko presega ravni, določene v tej objavi, na primer, kjer se uporablja ročni oddajnik v bližini opreme. V takih primerih bo morda treba uporabiti ukrepe za ublažitev.
