Autoclave tape works by changing color after exposure to temperatures commonly used in sterilization processes, typically 121°C in a steam autoclave. Chemical stripes on the tape changes from beige/tan to brown/black when the tape has been exposed to high temperature.

Of note, the presence of autoclave tape that has changed color on an item does not ensure that the product is sterile, as the tape will change color upon exposure only...for steam sterilization to occur, the entire item must completely reach and maintain 121°C for 15 minutes with proper steam exposure to ensure sterilization.
