After the sterilization process ,the round yellow/orange indicator will turn to Green or darker compared to the colour showed in the standard. Because the sterilization with ethylene oxyde depends deeply on percentages of humidity, temperature and concentration of the gas, there can be a wide range of final colours in the shade of green . The initial yellow colour will remain unchanged if one or more of the sterilization parameters have not been achieved.
Once the sterilization process has been properly achieved the initial yellow color of the indicator will turn to Green or darker, similar to the standard.
