Identify which wall and ceiling finishes the design accepts on the basis of an NFPA 286 test, then check that the finish schedule, the specifications, and the product data name the same product, substrate, and mounting in the same rooms. AI can flag substitutions and gaps; the architect and the authority having jurisdiction decide whether the finish is acceptable.
What does NFPA 286 cover?
NFPA 286 is the Standard Methods of Fire Tests for Evaluating Contribution of Wall and Ceiling Interior Finish to Room Fire Growth. NFPA’s page states that the standard describes a method for determining the contribution of interior finish materials to room fire growth, intended for wall and ceiling interior finish other than textile wall coverings, and that it is also known as the “room corner” test.
NFPA’s official NFPA 286 page identifies the 2024 edition as current when checked on October 11, 2026. Confirm the edition, local amendments, and project scope that actually govern the work. The publisher’s newest edition does not establish local adoption.
The adopted building or life safety code decides which finish classes each room needs and which tests it accepts; see the NFPA 101 guide and the IBC guide. NFPA 286 excludes textile wall coverings, which have their own test standard. Record which finishes rely on which test before comparing.
Gather the finish schedule and the product evidence
Collect the finish schedule and finish plans, the interior elevations and reflected ceiling plans, the code or life safety plan with occupancy and exit areas, the specifications for wall and ceiling finishes, wood paneling, acoustical panels, and decorative materials, and the manufacturer’s data and test reports for products accepted on a room corner test.
Designers often add feature walls and ceiling panels late. Upload the latest interior elevations so those products are checked along with the finish schedule.
Trace each tested finish to the rooms it covers
| Review question | Sources to compare | Decision to record |
|---|---|---|
| Finish basis | Finish schedule notes, specifications, code plan | Confirm which finishes the design accepts on a room corner test and that every source says the same. |
| Products | Finish schedule, specifications, product data | Check that each tested finish names the same product in the schedule, specifications, and data. |
| Substrate and mounting | Test report summary, wall types, interior details | Find finishes installed over a substrate or mounting that differs from the one the test documentation describes. |
| Rooms and exits | Finish plans, code plan, room names | Match each finish’s rooms with the occupancy and exit areas on the code plan. |
| Feature elements | Interior elevations, reflected ceiling plans, specifications | Identify wood slat walls, ceiling panels, and decorative finishes shown on elevations but missing from the schedule. |
| Substitutions | Submittals, product data, specifications | Ask the architect to confirm that substituted finishes carry equivalent test evidence. |
Floor finishes in corridors and exits connect to the NFPA 253 guide, and curtains and drapery to the NFPA 701 guide. The painting and finish schedule guide and the acoustical ceiling guide follow the same rooms from the specification side.
Example: a wood slat wall added on an elevation
Hypothetical example. A hotel lobby redesign adds a wood slat feature wall on the interior elevations. The finish schedule still lists painted gypsum board for that wall, and the specifications include no wood paneling section or test evidence for the slats.
The interior elevation adds a wood slat feature wall in the lobby, but the finish schedule lists painted gypsum board and the specifications contain no section or test evidence for the slats. Please confirm the finish and its basis of acceptance and coordinate the schedule and specifications.
The interior designer adds the product to the schedule and specifications with its test evidence. Acceptance is decided by the architect and the authority having jurisdiction.
Review interior finishes with Groundbook
Upload the current project PDFs and relevant specifications to Groundbook. Identify the governing issues and add the applicable NFPA 286 reference from a copy you are licensed to use, where the license permits uploading it. State the edition, amendments, review area, and known exclusions in your instructions.
Compare the finish schedule and plans, interior elevations, reflected ceiling plans, code and life safety plan, finish specifications, and product data and test reports. Flag tested finishes whose product, substrate, mounting, or rooms differ between sources, and finishes shown on elevations but missing from the schedule. Use the supplied NFPA 286 edition and adopted code where applicable and cite both sources.
Groundbook links each potential finding to the sheets involved and the reference you uploaded.
Document review does not test or classify a finish, interpret a test report, or approve a product. Those decisions remain with the architect and the authority having jurisdiction.
