A Class 1 indicator is commonly referred to as a process indicator or external chemical indicator. These indicators are used to demonstrate that the sterilization process has occurred by changing color or exhibiting some visible change when exposed to sterilization conditions, such as temperature and time. Class 1 indicators are designed to be placed outside of packages in a sterilization load and provide visual confirmation that the package has undergone the sterilization process, serving as an affirmation of procedural compliance.

These indicators are specifically designed to provide an initial level of assessment and do not guarantee the sterility of the item contained within. Instead, they indicate that the external conditions necessary for sterilization were met during the process. This makes them valuable for ensuring that sterilization protocols are followed and that the environment in which the items are processed is conducive to achieving sterility.

In contrast, biological indicators provide a more definitive measure of sterilization efficacy, while mechanical indicators generally refer to the instruments or machines used in the sterilization process itself, such as gauges or printouts reflecting cycles. Integrating indicators, on the other hand, offer a more robust understanding of the sterilization process but involve more complex chemical reactions than Class 1 indicators. Thus, the emphasis on Class 1 indicators being recognized as process indicators
