射頻屏蔽標(biāo)準(zhǔn)

射頻屏蔽標(biāo)準(zhǔn)射頻屏蔽是一種技術(shù)，旨在阻止電磁信號(hào)的傳播和干擾。射頻屏蔽標(biāo)準(zhǔn)是用于評(píng)估射頻屏蔽效果的指導(dǎo)性文件，通常由國(guó)際標(biāo)準(zhǔn)化組織、行業(yè)協(xié)會(huì)或政府機(jī)構(gòu)發(fā)布。以下是一些與射頻屏蔽標(biāo)準(zhǔn)相關(guān)的參考內(nèi)容：

1.國(guó)際電工委員會(huì)（IEC）發(fā)布的標(biāo)準(zhǔn)：

-IEC62209-1:2016-10"Humanexposuretoradiofrequencyfieldsfromhand-heldandbody-mountedwirelesscommunicationdevices-Humanmodels,instrumentation,andprocedures-Part1:Proceduretodeterminethespecificabsorptionrate(SAR)forhand-helddevicesusedincloseproximitytotheear(frequencyrangeof300MHzto6GHz)"

-IEC62209-2:2010"Humanexposuretoradiofrequencyfieldsfromhand-heldandbody-mountedwirelesscommunicationdevices-Humanmodels,instrumentation,andprocedures-Part2:Proceduretodeterminethespecificabsorptionrate(SAR)forwirelesscommunicationdevicesusedincloseproximitytothehumanbody(frequencyrangeof30MHzto6GHz)"

2.美國(guó)聯(lián)邦通信委員會(huì)（FCC）發(fā)布的標(biāo)準(zhǔn)：

-FCCPart15:“RadioFrequencyDevices”

-FCCPart18:“Industrial,Scientific,andMedicalEquipment”

3.歐洲電信標(biāo)準(zhǔn)協(xié)會(huì)（ETSI）發(fā)布的標(biāo)準(zhǔn)：

-ETSIEN301839-1V1.3.1:“ElectromagneticcompatibilityandRadiospectrumMatters(ERM);Humanexposuretoelectromagneticfieldsfromdevicesoperatinginthefrequencyrange0Hzto300GHz;Part1:Fieldsproducedbydevicesusedindirectproximitytothehumanbody”

4.國(guó)際電信聯(lián)盟（ITU）發(fā)布的標(biāo)準(zhǔn)：

-ITU-TK.52:“Methodsfortheassessmentoftheexposuretoelectric,magneticandelectromagneticfieldsofworkers,scientificradiofrequency,metrologicalandbroadcastingservices–Requirementsinthefrequencyrange100kHzto300GHz”

-ITU-RBS.1370:"Exchangeofdigitalprogrammaterialbetweenbroadcastingsystemsusingsatelliteconnectionsinthe11-12/10-14GHzfrequencyband:Systemdescription"

這些標(biāo)準(zhǔn)涵蓋了人體暴露于射頻場(chǎng)的方法、測(cè)量程序和限制值。其中，IEC和FCC的標(biāo)準(zhǔn)目標(biāo)是評(píng)估無(wú)線通信設(shè)備對(duì)用戶(hù)的電磁輻射的影響。這些標(biāo)準(zhǔn)通常規(guī)定了特定頻段的電磁場(chǎng)輻射限制值，以確保用戶(hù)的安全。

ETSI的標(biāo)準(zhǔn)主要關(guān)注電磁兼容性和短程設(shè)備的頻段使用。這些標(biāo)準(zhǔn)規(guī)定了設(shè)備在特定頻段范圍內(nèi)應(yīng)滿(mǎn)足的電磁輻射要求。

ITU的標(biāo)準(zhǔn)則是專(zhuān)門(mén)針對(duì)電磁場(chǎng)暴露的評(píng)估和測(cè)量。這些標(biāo)準(zhǔn)提供了評(píng)估人員暴露于電磁場(chǎng)的方法和測(cè)量程序，旨在保護(hù)從事電磁輻射工作的工作
