SIST EN 62209-2:2010

Human exposure to radio frequency fields from hand-held and bodymounted wireless communication devices - Human models, instrumentation, and procedures - Part 2: Procedure to determine the specific absorption rate (SAR) for wireless communication devices used in close proximity to the human body (frequency range of 30 MHz to 6 GHz) (IEC 62209-2:2010)

This part of IEC 62209 series is applicable to any wireless communication device capable of transmitting electromagnetic fields (EMF) intended to be used at a position near the human body, in the manner described by the manufacturer, with the radiating part(s) of the device at distances up to and including 200 mm from a human body, i.e. when held in the hand or in front of the face, mounted on the body, combined with other transmitting or non-transmitting devices or accessories (e.g. belt-clip, camera or Bluetooth add-on), or embedded in garments. For transmitters used in close proximity to the human ear, the procedures of IEC 62209-1:2005 are applicable. This standard is applicable for radio frequency exposure in the frequency range of 30 MHz to 6 GHz, and may be used to measure simultaneous exposures from multiple radio sources used in close proximity to human body. Definitions and evaluation procedures are provided for the following general categories of device types: body-mounted, body-supported, desktop, front-of-face, hand-held, laptop, limb-mounted, multi-band, push-to-talk, clothing-integrated. The types of devices considered include but are not limited to mobile telephones, cordless microphones, auxiliary broadcast devices and radio transmitters in personal computers. This International Standard gives guidelines for a reproducible and conservative measurement methodology for determining the compliance of wireless devices with the SAR limits. Because studies suggest that exclusion of features to represent a hand in human models constitutes a conservative case scenario for SAR in the trunk and the head, a representation of a hand is not included if the device is intended to be used next to the head or supported on or near the torso [73], [80]. This standard does not apply for exposures from transmitting or non-transmitting implanted medical devices. This standard does not apply for exposure from devices at distances greater than 200 mm away from the human body. IEC 62209-2 makes cross-reference to IEC 62209-1:2005 where complete clauses or subclauses apply, along with any changes specified.

Sicherheit von Personen in hochfrequenten Feldern von handgehaltenen und am Körper getragenen schnurlosen Kommunikationsgeräten - Körpermodelle, Messgeräte und Verfahren - Teil 2: Verfahren zur Bestimmung der spezifischen Absorptionsrate (SAR) von schnurlosen Kommunikationsgeräten, die in enger Nachbarschaft zum menschlichen Körper verwendet werden (Frequenzbereich von 30 MHz bis 6 GHz) (IEC 62209-2:2010)

Exposition humaine aux champs radio fréquence produits par les dispositifs de communications sans fils tenus à la main ou portés près du corps - Modèles du corps humain, instrumentation et procédures - Partie 2: Procédure pour la détermination du débit d'absorption spécifique produit par les dispositifs de communications sans fils utilisés très près du corps humain (gamme de fréquence de 30 MHz à 6 GHz) (CEI 62209-2:2010)

La CEI 62209-2:2010 s'applique à tout appareil de communication sans fils pouvant émettre des champs électromagnétiques (EMF) et destiné à une utilisation près du corps humain, de la manière décrite par le fabricant, la ou les parties rayonnantes de l'appareil étant situées à des distances inférieures ou égales à 200 mm du corps humain, c'est-à-dire lorsque l'appareil est tenu à la main ou devant le visage, porté près du corps, combiné à d'autres appareils ou accessoires émetteurs ou non (comme un clip de ceinture, une caméra ou un périphérique Bluetooth), ou intégré à des vêtements. Pour les émetteurs utilisés très près de l'oreille, les procédures de la CEI 62209-1:2005 sont applicables. La CEI 62209-2:2010 s'applique à l'exposition aux radiofréquences dans la gamme de fréquences de 30 MHz à 6 GHz, et elle peut être utilisée pour mesurer les expositions simultanées aux multiples sources radio utilisées très près du corps humain. Des définitions et des procédures d'évaluation sont fournies pour les catégories générales suivantes de types de dispositifs:  - portés près du corps,  - appareil posé sur le corps,  - appareil de bureau,  - appareil devant le visage,  - appareil tenu à la main,  - appareil portable,  - appareil fixé à un membre,  - appareil multibande,  - appareil poussoir de conversation,  - appareil intégré aux vêtements. Les types d'appareils pris en compte comprennent notamment les téléphones mobiles, les microphones sans fils, les appareils de diffusion auxiliaires et les  émetteurs radio intégrés dans les ordinateurs. La CEI 62209-2:2010 fournit des recommandations pour une méthode de mesure reproductible et conservatrice afin de déterminer la conformité des appareils sans fils aux limites du DAS.

Izpostavljenost ljudi elektromagnetnim sevanjem brezžičnih komunikacijskih naprav, ki se držijo v roki ali pritrdijo na telo - Modeli človeka, instrumenti in postopki - 2. del: Postopki za določanje stopnje specifične absorpcije (SAR) za brezžične komunikacijske naprave, ki se uporabljajo v bližini telesa (frekvenčno območje od 30 MHz do 6 GHz) (IEC 62209-2:2010)

Ta del IEC 62209 serij velja za vse brezžične komunikacijske naprave, zmožne oddajanja elektromagnetnih polj (EMF), namenjene za uporabo v bližini človeškega telesa, na način, ki ga je opisal proizvajalec, s sevalnimi deli naprave na razdalji do vključno 200 mm od človeškega telesa, t.j. kadar jih držijo v roki ali pred obrazom, kadar so nameščene na telo, združene z drugimi oddajnimi ali ne-oddajnimi napravami ali pripomočki (npr. zaponka za pas, kamera ali Bluetooth dodatek) ali vgrajene na oblačila. Za oddajnike, uporabljene v neposredni bližini človeškega ušesa, veljajo postopki iz IEC 62209-1:2005. Ta standard velja za izpostavljenost radijskim frekvencam v frekvenčnem razponu od 30 MHz do 6 GHz in se ga lahko uporabi za merjenje istočasne izpostavljenosti več radijskim virom, uporabljenim v neposredni bližini človeškega telesa. Definicije in postopki ocenjevanja so zagotovljeni za naslednje kategorije vrst naprav: nameščene na telo, podprte z telesom, namizne, nameščene pred obrazom, ročne, nameščene v naročju, nameščene na okončine, večpasovne, vrste pritisni-govori, vgrajene v oblačila. Vrste upoštevanih naprav vključujejo, vendar niso omejene na mobilno telefonijo, brezžične mikrofone, pomožne oddajne naprave in radijske oddajnike ter osebne računalnike. Ta mednarodni standard podaja smernice za ponovljivo in konservativno metodologija merjenja za določevanje skladnosti brezžičnih naprav s SAR mejami. Ker raziskave omenjajo, da izključitev lastnosti za predstavitev roke v človeških modelih pomeni konservativni scenarij za SAR v telesu in v glavi, predstavitev roke ni vključena, če je naprava namenjena za uporabo zraven glave ali podprta na ali nameščena zraven torza [73], [80]. Ta standard ne velja za izpostavljenost oddajnim medicinskim vsadkom in tistim, ki niso oddajni. Ta standard ne velja za izpostavljenost napravam na razdalji večji od 200 mm stran od človeškega telesa. IEC 62209-2 se sklicuje na IEC 62209-2:2005 kjer veljajo celotne klavzule ali podklavzule, skupaj z vsemi navedenimi spremembami.

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. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
The IEC work item “Evaluation of the Human Exposure to Radio Fields from Hand-Held and
Body-Mounted Wireless Communication Devices in the Frequency range 30 MHz to 6 GHz
(Human Models, Instrumentation, Procedures),” has the objective to measure the human
exposure from devices intended to be used at a position near the human body. This standard
was developed to provide procedures to evaluate exposures due to any electromagnetic field
(EMF) transmitting device when held in the hand or in front of the face, mounted on the body,
combined with other transmitters within a product, or embedded in garments. The types of
devices dealt with include but are not limited to mobile telephones, cordless telephones,
cordless microphones, auxiliary broadcast devices and radio transmitters in personal
computers. For transmitters used in close proximity to the human ear, specific absorption rate
(SAR) measurements should be performed using the procedures of IEC 62209-1:2005.
TC 106 has the scope to prepare international standards on measurement and calculation
methods used to assess human exposure to electric, magnetic and electromagnetic fields.
The task includes assessment methods for the exposure produced by specific sources. It
applies to basic restrictions and reference leve
