How many models can I include in one code listing?

As many as you want. There is no limit to the number of models included in a single listing, and each file may contain both systems and components. The only limitation is that all models in a given listing must be assessed to the same selection of codes and/or standards. If you want to have some models listed to certain codes and standards and other models listed to different codes and standards, you will need to submit a separate application to get a file for each set.
