IEC 62209-2-2019 人體接觸射頻領(lǐng)域從手持body-mounted無(wú)線(xiàn)通信設備,人體模型,儀表,和程序--第2部分:過(guò)程來(lái)確定特定吸收率(SAR)為無(wú)線(xiàn)通信設備中使用靠近人體(30 MHz到6 GHz的頻率范圍) Human exposure to radio frequency fields from hand-held and body-mounted wireless communication devices – Human models, instrumentation

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.dition 1.1 2019-05 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside Human exposure to radio frequency fields from hand-held and body-mounted 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) Exposition humaine aux champs radiofréquence produits par les dispositifs
