CISPR14-1和(he)(he)(he)CISPR14-2是家(jia)用(yong)電(dian)(dian)器(qi)(qi)最主要的(de)(de)電(dian)(dian)磁(ci)(ci)(ci)(ci)兼容標準，而(er)微波爐(lu)和(he)(he)(he)電(dian)(dian)磁(ci)(ci)(ci)(ci)爐(lu)（家(jia)用(yong)電(dian)(dian)磁(ci)(ci)(ci)(ci)感應器(qi)(qi)具）屬于工業、科學和(he)(he)(he)醫療（ISM）設備的(de)(de)2組(zu)B類設備，因此其電(dian)(dian)磁(ci)(ci)(ci)(ci)干擾(rao)特性應符(fu)合CISPR11的(de)(de)規定。歐盟地(di)區對應的(de)(de)家(jia)電(dian)(dian)電(dian)(dian)器(qi)(qi)電(dian)(dian)磁(ci)(ci)(ci)(ci)兼容標準為(wei)EN 55014-1和(he)(he)(he)EN55014-2，微波爐(lu)和(he)(he)(he)電(dian)(dian)磁(ci)(ci)(ci)(ci)爐(lu)則(ze)為(wei)EN55011。

在(zai)美(mei)國(guo)市(shi)場(chang)，普通家(jia)用電器屬于(yu)FCC Part15規定的(de)無意發(fa)射設備(bei)（Unintentional RF Equipments）,需(xu)要(yao)采用“驗證”于(yu)消費類ISM設備(bei)，需(xu)要(yao)滿(man)足FCC Part 18的(de)要(yao)求，認證模式則(ze)需(xu)選擇合格聲(sheng)明(ming)（DOC, Declaration of Conformity）或者認證（Certification）。
