A convenient method is proposed here to determine the relative accuracy of measuring ionization chamber (MIC). A non-dimensional quantity is presented here to characterize the relative accuracy of the testing MIC to the standard sample. Fire alarm with good repeatability and azimuth stability is used as the standard sample. The response threshold of the MIC to be measured is compared with that of the standard sample to determine its error and accuracy. This work may be benefit to testing laboratory, system manufactory and standard revision personnel.
