Where to find occupancy/location limits and exceptions for finish classes (Table 803.3)

Q: Where is the binding statement that says "use Table 803.3"?

The controlling directive is in § 803.3 : interior wall and ceiling finish shall have a flame spread index not greater than that specified in Table 803.3 for the group and location designated .

Q: What numeric flame‑spread ranges define Classes A/B/C?

Class A = flame spread 0–25 ; Class B = 26–75 ; Class C = 76–200 (smoke-developed indices must be ≤450 for these classifications) — see § 803.1.2 .

Q: Where are special rules for exhibit booths and trade shows?

See Appendix N — § N104.2 spells out that exhibit finishes are Class A when the building is not sprinklered, and can be Class B where the building is sprinklered throughout .

Homeowner summary: The California Fire Code requires wall and ceiling finishes to meet the fire performance class (A, B or C) shown in Table 803.3 for each occupancy and location. The code tells you where to look (see § 803.3) and how to prove compliance — either by ASTM E84/UL723 class indices or by NFPA 286 testing that meets the acceptance criteria. If the table cell requires Class A, you must supply a Class A material or an NFPA 286 test report that meets the limits; also make sure the finish is properly attached per the stability rule in § 803.2. file

What the code requires — plain English

The code requires that interior wall and ceiling finishes must meet the flame-spread/smoke performance specified for the occupancy and location shown in Table 803.3 — the table is the controlling map that tells you which finish Class (A, B or C) applies where. See § 803.3 for the controlling rule that ties finishes to Table 803.3 . Materials can be tested either by NFPA 286 or by ASTM E84/UL 723; NFPA 286 results that meet the acceptance criteria are treated as Class A where Class A is required (see § 803.1.1 and § 803.1.1.1) .

The single most important rule: interior wall and ceiling finishes must not exceed the flame-spread/smoke limits prescribed for the occupancy and location in Table 803.3 — compliance is verified by the test method and acceptance criteria specified in Chapter 8 (§ 803).

Requirements in detail

Where to look

The mandatory instruction that finishes follow the table is in § 803.3 (see Table 803.3) — this is the immediate starting point for every finish decision. § 803.3 ties a required finish class to each occupancy/location pairing .
Test methods and equivalent criteria are in § 803.1, § 803.1.1, § 803.1.1.1, and § 803.1.2 (NFPA 286 acceptance criteria and ASTM E84/UL 723 class definitions) .
Stability (how finishes are fastened/must remain intact under elevated temp) is in § 803.2 .
Specific material rules and exceptions are found in the related sections (e.g., § 803.1.3 through § 803.15 and Chapter 8 related sections such as § 806.6 for interior trim) — consult those for textile, foam, lockers, etc. file

Key, decision‑relevant values (summary table)

Note: the uploaded files did not include the printed contents of Table 803.3 itself. The table is referenced in § 803.3, but the actual table entries were not present in the documents provided. Below are the decision‑relevant performance thresholds and the rules you will use when you consult Table 803.3 in the official code.

Decision dimension	What to look for / numeric value	Code Reference
Which table controls required finish class	Table 803.3 (use to find Class A/B/C by occupancy & location)	§ 803.3
Class A (ASTM E84/UL 723)	Flame spread index 0–25; smoke-developed 0–450	§ 803.1.2
Class B (ASTM E84/UL 723)	Flame spread index 26–75; smoke-developed 0–450	§ 803.1.2
Class C (ASTM E84/UL 723)	Flame spread index 76–200; smoke-developed 0–450	§ 803.1.2
NFPA 286 acceptance (treated as Class A) — peak heat release	≤ 800 kW peak heat release during the test	§ 803.1.1.1 (4)
NFPA 286 acceptance — other limits	Flames not to spread to ceiling or sample outer extremity; no flashover; total smoke ≤ 1,000 m²	§ 803.1.1.1 (1–3,5)
Stability (attachment)	Material must not readily detach when exposed to 200°F (93°C) for 30 minutes	§ 803.2
Special occupancy exhibit (trade shows)	Exhibit finishes: if building not fully sprinklered → Class A; if building fully sprinklered → Class B (see exhibit/display rules)	Appendix N, § N104.2

(Again: the exact occupancy × location matrix — e.g., "Group A corridors = Class A" — is contained in Table 803.3 itself. That printed table was not included in the uploaded files, so the specific row/column values must be read from the official Table 803.3 in the code.)

How to use the table in practice (step sequence)

Identify the occupancy group and specific location (corridor, exit access, assembly area, patient room, storage, etc.). See Chapter 2/occupancy chapters for group definitions and Chapter 8 for locations referenced by the table. § 803.3 directs you to the table for the class assignment .
Read the Table 803.3 cell for that occupancy/location — it will list required finish Class (A, B, or C) or a conditional requirement (e.g., Class B unless sprinklered). If the table cell requires Class A, then either an ASTM E84 Class A product or an NFPA 286 tested product that meets the acceptance criteria is acceptable per § 803.1.1 / § 803.1.1.1 .
Confirm test reports (ASTM E84/UL 723 or NFPA 286) and attachment stability per § 803.2 .
Check special sections (e.g., textile wall coverings, foam plastics, interior trim) described in § 803.1.3–§ 803.15 and § 806.6 for additional limits or exceptions file.

Exceptions & special cases

NFPA 286 test results that meet the acceptance criteria are considered to be Class A for the purposes of Table 803.3 — see § 803.1.1 and § 803.1.1.1 (the NFPA 286 acceptance criteria) .
The code contains a number of material‑specific provisions and exceptions (for textiles, special plenum finishes, foam plastics, interior trim, lockers, etc.) in § 803.1.3 through § 803.15 and § 806.x; consult those sections for exceptions that alter test method or allowed classification (uploaded snippets reference those sections but full text may be in the code book) file.
For exhibit booths and trade shows, the finish requirement depends on sprinkler protection: non‑sprinklered exhibition areas require Class A finishes; sprinklered exhibition areas can permit Class B finishes — see § N104.2 (Appendix N) .
Interior trim has its own rule: except for certain foam plastics, interior trim is limited in size and class per § 806.6 (e.g., combustible trim may be limited to 10% of the wall or ceiling area and must meet the specified class) — consult that section for specifics .
If the table indicates different requirements based on whether a building is equipped with an automatic sprinkler system, the applicability and the sprinkler exception will be shown in Table 803.3; check the table cell for that condition (the table content itself is required to answer a specific occupancy+sprinkler question) — the controlling rule to consult is § 803.3 .

Common mistakes

Assuming ASTM E84 results alone are always sufficient — the code allows NFPA 286 as an alternative and NFPA 286 may be required to demonstrate equivalence to Class A for some materials; read § 803.1.1 and § 803.1.1.1 for the acceptance criteria .
Trying to apply a single class to an entire building without checking the location‑by‑location requirements in Table 803.3 (corridors, exits, assembly spaces, patient rooms often have different requirements) — § 803.3 mandates the table as the deciding authority .
Not verifying attachment stability — a material that meets flame spread requirements may still be unacceptable if it is not properly fastened per § 803.2 .
Misreading exhibit/display exceptions — Appendix N has special rules for trade shows (see § N104.2) that differ from the building‑wide requirements .

Worked example — step‑through (concrete scenario)

Scenario: You are finishing the interior walls and ceilings of a small restaurant (Group A, dining area, corridors and kitchen). You need to know whether a new wall panel product (ASTM E84 tested with flame spread index = 30, smoke-developed = 200) is acceptable.

Identify occupancy/location: dining room and corridors in a Group A occupancy. Start at § 803.3 to find the Table 803.3 requirement for "Group A — dining/assembly" and "corridor" locations (the exact Class required is shown in Table 803.3) .
Check the table cell: (because the actual Table 803.3 text was not available in the uploaded files, you must read Table 803.3 in the code to see whether the dining room and corridor require Class A or Class B/C, or whether sprinklering changes the requirement). The procedure is: if Table 803.3 requires Class A, then an ASTM E84 product with flame spread 30 (Class B per § 803.1.2) is NOT acceptable unless the product can instead be shown to meet NFPA 286 acceptance criteria (i.e., be tested under NFPA 286 and meet the limits in § 803.1.1.1) .
If Table 803.3 requires Class B or allows Class B when sprinklered and the building is sprinklered, the ASTM E84 Class B product (flame spread index 30 → Class B) would be acceptable per § 803.1.2, subject to proper installation and stability per § 803.2 file.
Always verify test reports and installation method; if NFPA 286 is used, confirm peak heat release ≤ 800 kW and total smoke ≤ 1,000 m² as required by § 803.1.1.1 .

(Important: because the Table 803.3 rows/columns were not included in the files you provided, the decisive step in this example — "what class does Table 803.3 require for Group A dining room/corridor" — must be read directly from Table 803.3 in the official code text. The procedural steps above show how you apply the table once you read the correct cell.)

8 INTERIOR FINISHES

User notes:

About this chapter: Chapter 8 contains the performance requirements for controlling fire growth and smoke propagation within buildings by restricting interior finish and decorative materials. The provisions of this chapter require materials used as interior finishes and decorations to meet certain flame spread index or flame propagation criteria and smoke development criteria based on the relative fire hazard associated with the occupancy.

Frequently asked questions

Where is the binding statement that says "use Table 803.3"?

The controlling directive is in § 803.3: interior wall and ceiling finish shall have a flame spread index not greater than that specified in Table 803.3 for the group and location designated .

If a product is tested to NFPA 286 and passes, can it be used where Class A is required?

Yes. Materials tested and meeting the NFPA 286 acceptance criteria are considered to comply with Class A where Class A is required — see § 803.1.1 and § 803.1.1.1 .

What numeric flame‑spread ranges define Classes A/B/C?

Class A = flame spread 0–25; Class B = 26–75; Class C = 76–200 (smoke-developed indices must be ≤450 for these classifications) — see § 803.1.2 .

Does having sprinklers always let me use a lower finish class?

Not automatically — Table 803.3 may include conditional cells that reduce the required class when the building is equipped with an automatic sprinkler system, but you must read the specific table cell for that occupancy/location (the table is the authoritative source per § 803.3) .

Where are special rules for exhibit booths and trade shows?

See Appendix N — § N104.2 spells out that exhibit finishes are Class A when the building is not sprinklered, and can be Class B where the building is sprinklered throughout .
