【Abstract】Based on the proficiency testing of magnetic field immunitytest capability of electricaland electronic components ofroadvehicles，this papercarries outtheverification schemeand sampledesignofradiation-ring method capabilityaccording tothestandardsof ISO11452-8and GB/T33014.8.Therelevanttechnical problemsarediscussed， anditisproposedthatthereceivingcoilisusedtoreceivethemagneticfield interferencesignalatadistanceof5cm fromtheradiationring，andtheACsignal isconvertedintoDCvoltagebyADCsampling technology.Thedesignscheme isconsistentwith theactual magnetic field immunityarrngementand testscheme.Inorder toverify thequalityof the sample，theuniformityandstabilityof thesample were testedandanalyzed.Aftersample deliveryandcapability verification，statisticalalgorithmswereusedtoefectivelyidentifythelaboratorywithunsatisfactoryresults.Forthiskind oflaboratory，thereasons fortheunsatisfactoryresultsare deeplyanalyzed，and thecoresponding improvement suggestionsareput forward fromthe technical point of view.
