Abstract Test data should be referenced to verify whether the performance of EMC
laboratory can meet specified technical requirements and design indexes. In the paper
some characteristics of the anechoic chamber are brief described,detailed introduction
has been provided for main technical requirements of the semi-anechoic chamber as
well as some notifications in chamber construction,in order to provide references in
establishing practical technical requirements of chamber construction and
acceptance requirements for the laboratory.
