Referenced Standards & Test Methods

Chapter 7 lists the external standards and test methods the CWIC incorporates (by citation) and directs you to the CWUIC sections that require those tests.

Last reviewed: July 6, 2026

Overview

Chapter 7 of the CWUIC collects the external standards and test methods the code relies on and lists them by issuing organization, standard ID, effective date and the CWUIC sections that reference them. The chapter explains that those external standards are incorporated into the code “to the extent of the reference,” so following the referenced test method is part of meeting the CWUIC requirement where a section cites it . The chapter also includes California‑specific SFM standards and test procedures (for example SFM 12‑7A series for decking and eaves) and cross‑references to other Title 24 parts and California codes .

Why this matters: the referenced standards provide the laboratory and field test procedures that demonstrate compliance for materials and assemblies exposed to wildfire (examples include ASTM E84 surface‑burning tests, ASTM E108/UL 790 roof covering tests, and SFM 12‑7A decking/eaves tests). Those standards are cited directly in multiple CWUIC provisions (for example §202, §501.4.1, §503.2.4 and §504.7.3.2) and are the technical basis for acceptance or rejection of products and assemblies under the code .

Where to look: start in Chapter 7 (Referenced Standards) for the master list and then follow the specific section citations (for example §504.x items referenced for exterior wall, roof, vent and deck tests). Appendix A also contains a referenced‑standards table for that appendix (see §A109.1) for appendix‑level references and cross‑adoptions .

    MATERIALS AND CONSTRUCTION METHODS FOR EXTERIOR WILDFIRE EXPOSURE

    5.3. Continued combustion. If penetration does not occur, continue observation for an additional 30 minutes or until all combustion has ceased.

    Note: An infrared thermometer has been found to be useful to detect the increase of temperature on the back side of the eaves and as an aid to identify the areas of potential combustion. 6. Observations. Note the time, location and nature of flame penetration.

    12-7A-3.9 Report. The report shall include a description of the eaves material, details of the construction of the eaves, moisture content of the framing and wood-based soffit elements as applicable, and point of flame penetration. Provide details on the time and reasons for early termination of the test.

    12-7A-3.10 Conditions of Acceptance. Should one of the three replicates fail to meet the Conditions of Acceptance, three additional tests may be run. All of the additional tests must meet the Conditions of Acceptance.

    1. Absence of flame penetration of the eaves or horizontal projection assembly at any time.
    2. Absence of structural failure of the eaves or horizontal projection subassembly at any time.
    3. Absence of sustained combustion of any kind at the conclusion of the 40-minute test.

    MATERIALS AND CONSTRUCTION METHODS FOR EXTERIOR WILDFIRE EXPOSURE

    DECKING

    SFM STANDARD 12-7A-4

    12-7A-4.1 Application. The minimum design, construction and performance standards set forth herein for unloaded decks are those deemed necessary to establish conformance to the provisions of these regulations. Materials and assemblies that meet the performance criteria of this standard are acceptable for use as defined in California Building Standards Code.

    12-7A-4.2 Scope. This standard evaluates the performance of decks (or other horizontal ancillary structures in close proximity to primary structures) when exposed to direct flames and brands. The under-deck flame exposure test is intended to determine the heat release rate (HRR) and degradation modes of deck or other horizontal boards when exposed to a burner flame simulating combustibles beneath a deck. The burning brand exposure test is intended to determine the degradation modes of deck or other horizontal boards when exposed to a burning brand on the upper surface.

    12-7A-4.3 Referenced document.

    1. ASTM D4444, Test Methods for Use and Calibration of Hand-Held Moisture Meters.

    2. ASTM E108, Test Methods for Fire Tests of Roof Coverings.

    3. California Building Code, Chapter 7A.

    4. UL 790, Standard Test Methods for Fire Tests of Roof Coverings.

    12-7A-4.4 Definitions.

    1. Deck boards. Horizontal members that constitute the exposed surface of the ancillary structure.
    2. Deck surface area. The test specimen area defined by the overall specimen length and width after assembly.
    3. Heat release rate. The net rate of energy release as measured by oxygen depletion calorimetry.

    • The California Code of Regulations (CCR), Title 19, Division 1 provisions that are found in the California Wildland-Urban Interface Code are a reprint from the current CCR, Title 19, Division 1 text for the code user’s convenience only.

Frequently asked questions

Which document controls when a referenced standard changes after adoption?

The CWUIC incorporates a standard only “to the extent of the reference” in the code; the specific CWUIC section that cites a standard controls how it applies. For newer or amended standards, the code edition and the effective date listed in Chapter 7 determine which version is applicable — consult the Chapter 7 listing for the standard’s effective date and the sections that reference it .

Can the authority having jurisdiction (AHJ) require additional testing or alternate methods?

Yes. Where an alternate material or method is proposed, the AHJ may require tests or other technical documentation to establish equivalency; testing must follow approved testing standards or an AHJ‑specified procedure when standards are not available .

Where are SFM wildfire test procedures (like decking and eaves tests) referenced?

SFM standards such as 12‑7A‑1 through 12‑7A‑4 (eaves, decking and related procedures) are listed and cross‑referenced in the Chapter 7 tables and in the California Referenced Standards material; those SFM test methods are cited by the CWUIC sections addressing exterior walls, decks and roof/soffit details (see the SFM 12‑7A listings and the detailed test summaries) .
