Title Noise suppression sheet for digital devices and equipment - Part 3: Characterization of parameters of noise suppression sheet
Project Number 22127
Abstract/Scope IEC 62333-3:2010 provides characterization of parameters for electromagnetic noise suppression sheet (NSS) for digital devices and equipment used in a frequency range between 30 MHz to 30 GHz. Guidance is given for uniform presentation of the properties of noise suppression sheet, intended for use in manufacturers and users technical data. NSS suppresses noise at its source, rather than absorbing noise at a distance. Therefore NSS is distinguished from RF wave absorbers used in free space. This standard addresses the following purposes of NSS manufacturers and users: - it assists users in understanding the published technical data in catalogues; - it guides users in selecting the most preferable NSS for each application; - it establishes measurement benchmarking for manufacturers of performance in new development of NSS; and - it maintains high reliability of NSS and applied products. The numerical values given in this standard are typical values of parameters (properties) of the related NSS. The purpose of NSS testing is the benchmarking of materials. Predictions of specific device performance values are not always easy or even possible. Every detailed material and NSS specification should be agreed between the user and the manufacturer.

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of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
