A comparison CCEM-K3 [1] was finished in 2001 with a good result: a relative expanded uncertainty of 4·10-6 could be achieved. However, this old comparison did not cover all regions, a repetition is necessary. To achieve again the necessary low uncertainty quite high requirements on the stability of the standard have to be fulfilled. A good knowledge of the quality of inductance standards is therefore inevitable. This paper describes the parameters which are important to carry out the comparison.","PeriodicalId":415488,"journal":{"name":"2016 Conference on Precision Electromagnetic Measurements (CPEM 2016)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-08-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129528154","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
