ASTM/NFPA Fire Standards: For Toilet Partitions

For toilet partition fire requirements, match the exact product and its test documentation to the project's specifications and adopted code. A general material name or a Class A marketing statement is not enough to confirm a proposed installation. Ask the design professional or reviewing authority which test, edition and acceptance criteria apply before ordering.

What ASTM E84 measures

ASTM E84 compares surface-burning behavior under specified test conditions and reports flame-spread and smoke-developed indices. ASTM explains that it does not measure heat transmission through the surface or establish that a material is noncombustible from its flame-spread index alone. See ASTM's E84 scope and limitations.

Do not read a surface-burning classification as an hourly fire-resistance rating or a statement that a partition is fireproof. When a specification asks for a classification, request the underlying test report and the criteria used to assign it. The report must identify the product being supplied.

What NFPA 286 measures

NFPA 286 evaluates how an interior wall or ceiling finish contributes to fire growth in a room test. Its measurements include fire growth, heat release, flame extension and smoke. This is a different test from E84. See NFPA's description of NFPA 286.

A statement that a product was tested does not, by itself, identify the required acceptance criteria or confirm approval for your project. Obtain the results and have the project reviewer confirm their application. Do not assume an E84 result substitutes for an NFPA 286 requirement.

What to request for the proposed partitions

1. Project requirements: the applicable specification, adopted code edition and any local amendments or review conditions.
2. Product identity: manufacturer, series, material, thickness, finish and proposed mounting arrangement.
3. Test documentation: the full report or accepted evaluation document, including the laboratory, test method and edition, tested construction and results.
4. Scope confirmation: whether the report covers the product and installation being ordered, including any limitations.
5. Review decision: written confirmation from the responsible project reviewer when the specification or report is unclear.

Choosing a material and completing the submittal

Compare partition materials for the restroom's moisture exposure, maintenance and privacy needs, then check the fire documentation for the selected product. Do not assign one rating to every HDPE, laminate, phenolic or metal partition, or substitute a discontinued trade name for the tested product.

Send us the layout and project specification so we can help identify products and request the relevant manufacturer documents. Product selection and a price quote do not replace the project's code review.
