Which of the following best represents the comprehensive content that should be included in a specimen interior door specification?

• A. Only the door size and installation location
• B. Material, core, finish, fire rating, acoustical rating, hinge type, hardware set, locksets, door/frame schedule, and installation tolerances
• C. Only finish and aesthetic details
• D. Only the lockset and hinge type

Answer: (B)

A specimen interior door specification must capture every performance, interface, and fabrication detail so the door fits, functions, and complies with code. The comprehensive set includes material, core, finish, fire rating, acoustical rating, hinge type, hardware set, locksets, door/frame schedule, and installation tolerances. Material and core affect durability and how the door behaves in use; finish provides protection and the desired appearance; fire rating and acoustical rating address safety and sound performance; hinge type and hardware set govern operation and compatibility with the frame and wall; locksets relate to security; the door/frame schedule defines exact dimensions and how the door interfaces with the surrounding structure; installation tolerances ensure a proper fit, alignment, and reliable performance in service. Alternatives that focus only on size and location, or only on finish, or only on lockset and hinge, miss essential performance, safety, and coordination details.
