A temperature multiplication chemical indicator must change color by a temperature multiplication condition step-by-step. The chemical indicator of new development inspected performance evaluation with Steam CIER (Chemical indicator Evaluator Resistometer) Vessel. In addition, I let change of color performance of a chemical indicator and a change of central temperature of a standardized test pack used a normal steam sterilizer, and air exclusion rate change and inspected it. As a result, a thing having the performance that a chemical indicator changed color in a processing condition of 121°C and 134°C step-by-step of new development was inspected. I suggested that the system, which supposed an approximate sterility assurance level, used color-difference meter with this chemical indicator and could build it.
