Abstract

ISO 18472:2006 specifies the requirements for test equipment to be used to test chemical and biological indicators for steam, ethylene oxide, dry heat and vaporized hydrogen peroxide processes for conformity to the requirements given in ISO 11140-1 for chemical indicators, or the requirements given in the ISO 11138 series for biological indicators. ISO 18472:2006 also provides informative methods useful in characterizing the performance of biological and chemical indicators for intended use and for routine quality control testing.
