The ANSI/ISA–95 standard states that the material model has a concept called material class and each class can have one or more custom properties. A specific material can belong to a material class. Through this association, each material belonging to the class has the same set of custom properties.

Example: Create a material class with custom properties
You can configure a material class of Coal with two custom properties: Carbon and Sulphur.

You can configure five specific materials (for example, Raw Coal, Processed Coal, and so on), and associate them with the Coal class. Each of the materials belonging to the material class Coal will inherit the two custom properties: Carbon and Sulphur.
Add a material class
You can define a material class to organize similar materials together and give them the same custom fields.
