CE認證SAR檢測概述:

      SAR是指電磁波吸收比值或比吸收率,在CE認證中標準采用;

           限量標準:

                 EN 50360-2001 Product standard todemonstrate the compliance of mobile phones with the basic
                 restricions related to human exposure to electromagnetic fields(300MHz - - 3GHz)


          產(chǎn)品標準:

                EN 20556-2013Product standard to demonstrate compliance of radio frequency fields from hand held
                and body-mounted wireless communication devices used by the general public(30MHz - - 6GHz)


          技術(shù)標準:

                EN 62209-1-2006 Human exposure to radio frelds from hand-held and body-mounted wireless
                communication devices - Human models,instrumentarion,and procedures -Part1:Procedure to
                determine the specific absorption rete(SAR)for hand-held devices used in close proximity to
                the ear (frquency range of 300 MHz to 3GHz)

                EN 62209-2-2010 Human exposure to radiofiequency fields from hand-held body-mounted wireless
                communication devices - Human  models,instrumentarion,and procedures -Part2:Procedure to
                determine the specific absorption rete(SAR)for wireless communication devices used in close
                proximity to the huma body (frquency range of 30 MHz to 6GHz)

                 EN 62479-2010 Assessment of the compliance of low power electronic and electrical apparatus 
                 with the basic restrictions related human exposure to electromagneetic (10 MHz - 300GHz)



               其中,技術(shù)標準EN 62209-2-2010作為產(chǎn)品標準EN 50566-2013的技術(shù)規(guī)范性文件,定義為body
              SAR檢測距離,由產(chǎn)品制造商按照定義其產(chǎn)品預(yù)期使用的典型距離。如手機類,body SAR可定義
              并采用10mm/ 15mm作為評估距離。

        標準重大變更:
           
                2014年,法國對標準EN 50566-2013提出異議,指出應(yīng)考慮便攜和移動式產(chǎn)品的具體使用條件,
                并應(yīng)提出body SAR的評估距離。歐盟經(jīng)過評估后認為該提議合理,需對EN50566進行修訂補充,
                內(nèi)容如下:
                
                警示:基于安全性目標,結(jié)合指令1999/5/EC的Article 3(1)(a)條款以及附件l至指令2006/95/EC,
                規(guī)定在使用此測試標準時應(yīng)符合相關(guān)間隔距離的規(guī)定,并能反映出設(shè)備實際日常使用時的真實情況,
                確保公眾在使用|(30MHz - 6GHz)手持式和身體佩戴式無線通信設(shè)備時的安全性。
                舉例說明:對于肢體SAR評估(限值為4W/kg),測量間隔距離為0(設(shè)備直接接觸模型);對于身體
                body SAR (限值為2W/kg),測量間隔距離可以是幾mm。
                { Warning: The application of this publication shall observe certain conditions relating to the separrtion
                 distance,reflecting the practical day to day use, ensuring the safe use of handheld and body-mounted 
                 wireless communication devies used by the general public(30 MHz - 6GHz),for the purposes of the
                 safety objectIves provided for in Article 3 (1)(a)of Directive 1999/5/EC,in conjunction with Annex l to
                 Directve 2006/95/EC.For example,for limb SAR measurements (limit 4 W/kg),  on separation distance
                 may be used (device in contact );for trunk SAR measurements (limit 2 W/kg)a separation distance of
                 less than a few millimetres may be used.}




                 據(jù)悉,歐盟將很有可能在經(jīng)期,既2016年中,推行:肢體SAR測量(限值為4W/kg),測量間隔距離為0;body
                 SAR (限值為2W/kg),測量間隔距離為5mm。因此對于近期計劃開展歐盟SAR檢測的項目各位負責(zé)人
                 莫森檢測特別提醒:請?zhí)崆白屑氉龊醚邪l(fā)評估,避免在認證時出現(xiàn)fail,而使整個認證周期超出控制范圍。
