ISO 18472:2006规定了用于测试蒸汽，环氧乙烷，干热和蒸发过氧化氢过程的化学和生物指标的测试设备的要求，以符合ISO 11140-1中关于化学指标或要求的要求在ISO 11138系列中给出生物指标。 ISO 18472:2006还提供了有用的特征，用于表征预期用途的生物和化学指标的性能以及常规质量控制测试

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.
