標(biāo)準(zhǔn)FCC?Part 15 B中B代表的意思
　　

其實(shí)準(zhǔn)確的說(shuō)?FCC?Part?15?B應(yīng)該是FCC?Part?15?Class?B（B級(jí)數(shù)字裝置）。
　　Class?A和Class?B的定義：
　　Class?A?digital?device－A級(jí)數(shù)字裝置
　　A?digital?device?that?is?marketed?for?use?in?a?commercial,?industrial?or?business?
environment,?exclusive?of?a?device?which?is?marketed?for?use?by?the?general?public?
or?is?intended?to?be?used?in?the?home.投放市場(chǎng)供在商業(yè)、工業(yè)或商務(wù)環(huán)境中使用的數(shù)字裝置，但不包括投放市場(chǎng)供一般公眾或家庭使用的裝置。
　　Class?B?digital?device－B級(jí)數(shù)字裝置
　　Class?B?digital?device.?A?digital?device?that?is?marketed?for?use?in?a?residential?
environment?notwithstanding?use?in?commercial,?business?and?industrial?
environments.?Examples?of?such?devices?include,?but?are?not?limited?to,?personal?
computers,?calculators,?and?similar?electronic?devices?that?are?marketed?for?use?by?
the?general?public.?Note:?The?responsible?party?may?also?qualify?a?device?intended?
to?be?marketed?in?a?commercial,?business?or?industrial?environment?as?a?Class?B?
device,?and?in?fact?is?encouraged?to?do?so,?provided?the?device?complies?with?the?
technical?specifications?for?a?Class?B?digital?device.?In?the?event?that?a?particular?
type?of?device?has?been?found?to?repeatedly?cause?harmful?interference?to?radio?
communications,?the?Commission?may?classify?such?a?digital?device?as?a?Class?B?
digital?device,?regardless?of?its?intended?use。
　　投放市場(chǎng)不僅供在商業(yè)、工業(yè)或商務(wù)環(huán)境中使用而且要在居住環(huán)境中使用的數(shù)字裝置。這類(lèi)裝置的例子包括（但不限于）：個(gè)人計(jì)算機(jī)、計(jì)算器以及其它投放市場(chǎng)供一般公眾使用的類(lèi)似電子裝置。注：職責(zé)部門(mén)也可以把投放市場(chǎng)以供商業(yè)、工業(yè)或商務(wù)環(huán)境中使用的裝置定義為B級(jí)裝置；事實(shí)上FCC也鼓勵(lì)這一舉措，只要該裝置能滿足B級(jí)裝置的技術(shù)規(guī)范。若某類(lèi)型裝置反復(fù)地對(duì)無(wú)線電通訊產(chǎn)生有害干擾，則FCC可能會(huì)將之歸為B級(jí)數(shù)字裝置而不管其用途如何。
　　下面是FCC?PART?15目錄章節(jié)內(nèi)容：
