What is the fire rating for door 062.3 according to the sample drawings?

The fire rating of a door is essential in construction for ensuring safety and compliance with building codes. If door 062.3 is indicated as "Not rated," this means that it does not have any fire resistance capability designed into it. This is typical for doors that are not meant to serve as fire barriers or do not need to withstand fire for a specified duration.

Such doors are usually found in areas where fire resistance is not an issue, or where the architectural design does not require a rated assembly. For example, they could be used in interior spaces without strict fire code regulations that apply to exits or other critical areas. Fire-rated doors, on the other hand, are designed to restrict fire and smoke spread and would carry specifications for how long they can perform that function, such as being rated for 30, 60, or 90 minutes.

In sum, stating that door 062.3 is "Not rated" correctly identifies it as a door without specific fire resistance attributes, which is critical for ensuring correct interpretations of safety measures within the building's design.
