Noise suppression sheet for digital devices and equipment - Part 3: Characterization of parameters of noise suppression sheet (IEC 62333-3:2010)

This part of IEC 62333 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.

Plaque réduisant le bruit des dispositifs et appareils numériques - Partie 3: Caractérisation des paramètres des plaques réduisant le bruit (CEI 62333-3:2010)

La CEI 62333-3:2010 présente la caractérisation des paramètres pour les plaques réduisant le bruit électromagnétique des dispositifs et appareils numériques utilisés dans une gamme de fréquences allant de 30 MHz à 30 GHz. Elle indique comment présenter uniformément les propriétés des plaques réduisant le bruit, dans le cadre des données techniques pour les fabricants et les utilisateurs. Les plaques réduisant le bruit réduisent le bruit à sa source, plutôt que de l'absorber à une certaine distance. Ainsi, les plaques réduisant le bruit se distinguent des absorbeurs d'ondes RF utilisés dans l'espace libre. La présente norme aborde les besoins suivants des fabricants et des utilisateurs de plaques réduisant le bruit: - aider les utilisateurs à comprendre les données techniques publiées dans les catalogues; - guider les utilisateurs dans leur choix de plaques réduisant le bruit pour chaque application; - établir des mesures de référence pour les fabricants qui développent de nouvelles plaques réduisant le bruit; et - maintenir une fiabilité élevée des plaques réduisant le bruit et des produits appliqués. Les valeurs numériques données dans la présente norme sont des valeurs typiques de paramètres (propriétés) des plaques réduisant le bruit. Les essais sur les plaques réduisant le bruit ont pour objectif d'établir des références pour les matériaux. Il n'est pas toujours facile, voire possible, de prédire les valeurs des performances spécifiques de certains dispositifs. Il convient que chaque spécification particulière des plaques réduisant le bruit et des matériaux fasse l'objet d'un accord entre l'utilisateur et le fabricant.

Protišumni list za digitalne naprave in opremo - 3. del: Določanje lastnosti parametrov protišumnega lista (IEC 62333-3:2010)

Ta del IEC 62333 predpisuje določanje lastnosti parametrov protišumnega lista (NSS) za digitalne naprave in opremo, uporabljeno za frekvenčni razpon od 30 MHz do 30 GHz. Vodilo je podano za enotno predstavitev lastnosti protišumnega lista in je namenjeno za uporabo pri tehničnih podatkih proizvajalcev in uporabnikov. NSS zaduši hrup pri samem viru in ne absorbira zvoka na razdalji. Zato se NSS razlikuje od RF valovnih absorberjev, uporabljenih v prostem prostoru.
Ta standard obravnava naslednje namene NSS proizvajalcev in uporabnikov:
- uporabnikom pomaga pri razumevanju tehničnih podatkov iz katalogov;
- uporabnike vodi pri izbiri najbolj zaželenega NSS za vsako uporabo;  
- vzpostavlja primerjanje meritev delovanja za proizvajalce pri
razvoju novih NSS; in
- vzdržuje visoko zanesljivost NSS in uporabljenih produktov.
Numerične vrednosti, podane v tem standardu, so običajne vrednosti parametrov (lastnosti) povezanih NSS. Namen NSS testiranja je primerjanje materialov. Napovedi delovanja določene naprave niso vedno preproste ali celo možne. Vsak podroben material in NSS specifikacija bi morala biti dogovorjena med uporabnikom in proizvajalcem.

NOISE SUPPRESSION SHEET FOR DIGITAL
DEVICES AND EQUIPMENT –
Part 3: Characterization of parameters of noise suppression sheet

FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication.
