# Creating asset classes
<a name="custom-asset-class"></a>

Amazon Monitron offers four [default machine classes based on ISO 20816 Standards](https://docs.aws.amazon.com/Monitron/latest/user-guide/assets-chapter.html). When you add an asset position, you can choose any of these four default classes as the machine class to use for detecting anomalies with your assets. Amazon Monitron then uses the assigned asset class to generate warnings and alarms on asset condition.

If your asset types don't align with the default machine classes offered by Amazon Monitron, you can create custom machine classes for your assets. Once created, these custom classes are available to be assigned to all asset positions in a project. 

**Important**  
Custom classes can only be created using the Amazon Monitron web app. Only the Amazon Monitron project admin can create, update, and delete custom asset classes.
