Title Information technology equipment - Immunity characteristics - Limits and methods of measurement
Project Number 8275
Abstract/Scope 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.

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
