CE认证SAR检测概述:

      SAR是指电磁波吸收比值或比吸收率,在CE认证中标准采用;

           限量标准:

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


          产品标准:

                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)


          技术标准:

                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,技术标准EN 62209-2-2010作为产品标准EN 50566-2013的技术规范性文件,定义为body
              SAR检测距离,由产品制造商按照定义其产品预期使用的典型距离。如手机类,body SAR可定义
              并采用10mm/ 15mm作为评估距离。

        标准重大变更:
           
                2014年,法国对标准EN 50566-2013提出异议,指出应考虑便携和移动式产品的具体使用条件,
                并应提出body SAR的评估距离。欧盟经过评估后认为该提议合理,需对EN50566进行修订补充,
                内容如下:
                
                警示:基于安全性目标,结合指令1999/5/EC的Article 3(1)(a)条款以及附件l至指令2006/95/EC,
                规定在使用此测试标准时应符合相关间隔距离的规定,并能反映出设备实际日常使用时的真实情况,
                确保公众在使用|(30MHz - 6GHz)手持式和身体佩戴式无线通信设备时的安全性。
                举例说明:对于肢体SAR评估(限值为4W/kg),测量间隔距离为0(设备直接接触模型);对于身体
                body SAR (限值为2W/kg),测量间隔距离可以是几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.}




                 据悉,欧盟将很有可能在经期,既2016年中,推行:肢体SAR测量(限值为4W/kg),测量间隔距离为0;body
                 SAR (限值为2W/kg),测量间隔距离为5mm。因此对于近期计划开展欧盟SAR检测的项目各位负责人
                 莫森检测特别提醒:请提前仔细做好研发评估,避免在认证时出现fail,而使整个认证周期超出控制范围。
