Installation, certification and related referenced standards (12‑16 series)

This hub explains CRSC 12‑16: DSA‑administered installation and certification standards for gas shutoff and excess‑flow devices and the national standards they reference.

Last reviewed: July 6, 2026

Overview

The 12‑16 series of the California Referenced Standards Code sets product certification and installation requirements for gas‑safety devices and related engineered components administered by the Division of the State Architect (DSA). Key DSA standards in this group include the California standard for earthquake‑actuated automatic gas shutoff systems and the California standard for residential excess‑flow actuated automatic gas shutoff valves, which identify the external consensus standards used for certification and testing. See § 12‑16‑101 for the ASCE requirement for earthquake‑actuated shutoff devices and § 12‑16‑201 for the ASTM/ANSI requirements for excess‑flow valves .

These provisions matter because they tie device certification, accepted test methods and installation references to specific national standards (ASCE, ASTM, ANSI/CSA) and to California Building/Plumbing Code chapters where installations must conform. The code cross‑references these chapters and indicates the enforcing authority and applicable Title 24 provisions for installations and approvals (see the chapter listing for 12‑16 and its Title 24 references) .

Stakeholders — manufacturers, testing labs, design professionals and permitting officials — rely on the 12‑16 series to identify which consensus documents DSA uses for product approval and what installation code provisions apply (for example, installations are required to conform with CCR Title 24, Part 5) .

    12-3-1.3 These requirements cover releasing systems intended for use on the interior side of doors or windows in all climatic locations.

    12-3-1.4 These requirements do not evaluate the ability of the releasing system or obstructions to resist an external forced entry attack.

    12-3-1.5 These requirements do not evaluate the ability of the releasing system or obstructions to be opened or removed from the exterior of the residential dwelling unit by emergency response personnel during rescue operations.

    12-3-1.6 Products covered by these requirements are intended for installation in dwelling units to protect door and window openings that are designated by the California Building Standards Code to be used as the secondary means of escape from the living area.

    12-3-1.7 Products covered by these requirements are not intended to be used to protect doors in means of egress path for nonresidential occupancies, the common egress path of multifamily residential dwelling units or the primary means of egress path in a single-family dwelling unit.

    1. The specimen shall be suspended vertically with its lower edge 2 inches (51 mm) above the top of a [3] / 8 inch (9.5 mm) diameter Bunsen Burner. The test shall be performed in a draft-free area.

    2. The flames from the burner shall be 4 inches (101 mm) long and shall be adjusted with sufficient air supply to eliminate any yellow flame tips but without any distinct inner blue cone.

    3. The specimen shall be exposed to the flame at each corner and at not less than one other point along the lower edge. Each exposure shall be of sufficient duration to determine if the material will ignite and continue to burn, but shall be not less than 20 seconds.

    4. The criteria for acceptance shall be as follows: (A) There shall be not more than intermittent flaming appreciably beyond the area exposed to the test flame. (B) Flame shall not reach the top of the specimen. (C) On removing the test flame there shall be not more than 1 second of after flaming except there may be nonprogressive flaming of short duration in areas of accumulated char which were directly exposed to the test flame.

    Section 12-7-502

    (a) Framed rigid combustible decorative material. Rigid combustible decorative material and assemblies of materials not more than [1] / 4 inch (6 mm) in thickness used for folding doors, room dividers, decorative screens and similar applications, and which are installed with all edges protected, shall conform to the following:

    1. All exposed edges shall be protected with frames of metal or other noncombustible material, or solid wood of minimum [1] / 4 inch (6 mm) dimension.

    2. The total square foot area of the material shall not exceed ten percent of that of the floor area of the room in which the material is installed.

    3. When tested as follows, flames shall not reach the top edge of the specimen. The test shall be conducted in a draft free area, on a specimen of the material 12 inches by 12 inches (305 mm by 305 mm) suspended at a 45-degree angle from the horizontal with the upper and lower edges in a horizontal plane. The test flame shall be 3 inches (76 mm) long from a Bunsen burner of approximately [1] / 2 -inch (13 mm) inside diameter with the air supply completely shut off. The burner shall be positioned so that its top is 1 inch (25 mm) vertically below a point on the lower surface of the test specimen, 1 inch (25 mm) up from its lower horizontal edge and midway between the inclined edges. The exposure to the test flame and the duration of test shall be for a period of 2 minutes.

Frequently asked questions

Who is the responsible authority for standards in the 12‑16 series?

The Division of the State Architect (DSA) administers the 12‑16 standards; the standards themselves identify DSA as the certifying authority for the earthquake‑actuated and excess‑flow device standards .

Do installations of certified devices still need to follow Title 24 building/plumbing provisions?

Yes. Each installation of a customer‑owned device that satisfies the DSA standard must be installed in accordance with the applicable California Plumbing/Building Code (CCR Title 24, Part 5) as noted in § 12‑16‑101.1 and § 12‑16‑201.1 .

What external consensus standards are referenced in these sections?

Examples include ANSI/ASCE/SEI 25‑16 for earthquake‑actuated automatic gas shutoff devices and ASTM F2138 and ANSI Z21.93/CSA 6.30 for excess‑flow valves; these are named explicitly in the respective sections for DSA certification .
