True or False: All provisions in the appendices of the IMC must apply in all cases.

The assertion that all provisions in the appendices of the International Mechanical Code (IMC) must apply in all cases is false. The appendices are intended to be supplemental information that may provide guidance or additional details for specific situations, but they are not automatically mandatory for every scenario. Instead, the application of provisions can vary based on factors such as the type of building, the specific mechanical systems in use, and local amendments to the code.

This flexibility allows for variations in construction methods, environmental considerations, and the unique needs of different projects. Therefore, while some provisions in the appendices may be relevant or useful, their universal applicability is not guaranteed. Each situation may dictate the need for adherence to only certain provisions or none, aligning with the specific requirements or exceptions established by local jurisdictions or the nature of the mechanical systems being installed or modified.
