CRSC · California Referenced Standards Code
How do the 12‑16 standards reference external standards (ASTM, ANSI, ASCE, CSA)?
The CRSC requires the Division of the State Architect to use **ANSI/ASCE/SEI 25‑16** for earthquake‑actuated gas shutoff devices and **ASTM F2138‑12(2017)** plus **ANSI Z21.93‑2017/CSA 6.30‑2017** (for up to **5 psig**) for residential excess‑flow valves; installations must follow the California Plumbing Code (CCR Title 24, Part 5).
Last reviewed: July 6, 2026
What the code requires — plain English
The Division of the State Architect requires that specific device types be certified to named external standards. For earthquake‑actuated automatic gas shutoff devices the controlling standard is ANSI/ASCE/SEI 25‑16 under § 12-16-101. For residential excess‑flow valves the controlling standards are ASTM F2138‑12(2017) and ANSI Z21.93‑2017/CSA 6.30‑2017 (for pressure up to 5 psig) under § 12-16-201. Each device installation must also comply with the California Plumbing Code (CCR Title 24, Part 5) as stated in § 12-16-101.1 and § 12-16-201.1.
The single most important rule: the CRSC names the exact external standard the Division of the State Architect uses for certification — you must use the cited standard for certification and follow the California Plumbing Code for installations.
Requirements in detail
Which external standards are adopted (and for what)
- Earthquake‑actuated automatic gas shutoff devices — adopt ANSI/ASCE/SEI 25‑16 as the applicable certification standard (§ 12-16-101). The language ties certification to the Division of the State Architect.
- Residential excess‑flow valves for natural gas service — adopt ASTM F2138‑12(2017) and ANSI Z21.93‑2017/CSA 6.30‑2017 (the latter specified for pressure up to 5 psig) as the applicable certification standards (§ 12-16-201).
Installation requirement
- Regardless of certification to the named standard, each installation of a customer‑owned device that satisfies the standard must be made in accordance with the California Plumbing Code (CCR Title 24, Part 5) (§ 12-16-101.1 and § 12-16-201.1).
Decision‑relevant dimensions (quick reference)
| Referenced standard | Device type / scope | Key threshold / note | Code Reference |
|---|---|---|---|
| ANSI/ASCE/SEI 25‑16 | Earthquake‑actuated automatic gas shutoff devices | Certification standard used by Division of the State Architect | § 12-16-101 |
| ASTM F2138‑12(2017) | Excess flow valves for natural gas service | Certification standard used by Division of the State Architect | § 12-16-201 |
| ANSI Z21.93‑2017 / CSA 6.30‑2017 | Excess flow valves for natural and LP gas | Applies for pressure up to 5 psig (explicitly listed) | § 12-16-201 |
| — | Installation of certified, customer‑owned devices | Must follow California Plumbing Code (CCR Title 24, Part 5) | § 12-16-101.1, § 12-16-201.1 |
How to read the CRSC language
- The CRSC language is directive: "shall be the applicable standard used by the Division of the State Architect for the certification of these devices." That means the named standard is the required benchmark for certification by that agency, not an optional guidance document.
Exceptions & special cases
- The sections retrieved do not list exceptions to the requirement that those specific standards are used for certification; the text uses mandatory language ("shall be the applicable standard") for each device type.
- The CRSC sections provided do not describe alternate certification pathways, grandfathering, test lab accreditation, or administrative procedures the Division of the State Architect follows to issue a certification. Those procedural details are not covered in the retrieved text and must be obtained from the Division or other implementing regulations.
Common mistakes
- Assuming any edition of a standard is acceptable. The CRSC cites specific editions/years (for example, ANSI/ASCE/SEI 25‑16 and ASTM F2138‑12(2017) / ANSI Z21.93‑2017), so confirm you are using the edition named in the section.
- Confusing certification requirements with installation rules. Certification follows the named external standard; installation must follow the California Plumbing Code as required by § 12-16-101.1 and § 12-16-201.1.
- Ignoring the pressure limit language. For excess‑flow valves the CRSC explicitly pairs ANSI Z21.93‑2017/CSA 6.30‑2017 with the qualification "with Pressure up to 5 psig" — don’t certify a valve for higher pressure under that particular reference without confirming applicability. 5 psig is the decision threshold called out in § 12-16-201.
Worked example — concrete scenario
Scenario: A manufacturer seeks DSA certification for a residential excess‑flow valve intended for a low‑pressure natural gas service at 4 psig and for customer installation.
Step 1 — Identify the certification standard: the CRSC requires certification to ASTM F2138‑12(2017) and ANSI Z21.93‑2017/CSA 6.30‑2017 (for pressure up to 5 psig) for excess flow valves (§ 12-16-201). Because 4 psig ≤ 5 psig, the ANSI/CSA standard listed applies.
Step 2 — Confirm the valve meets the referenced test/specification requirements in those standards (manufacturer testing and documentation). The CRSC text requires the Division of the State Architect to use those standards for certification — the manufacturer must provide evidence of compliance to those standards to the DSA.
Step 3 — Installation requirement: when the customer or installer installs the certified valve, the installation must conform to the California Plumbing Code (CCR Title 24, Part 5) as required by § 12-16-201.1. So the installer should follow the Plumbing Code provisions for fuel‑gas piping, connections, labeling, and inspection.
Note: The CRSC text does not provide the DSA’s internal certification checklist or exact documentary evidence required; obtain that administrative detail directly from the Division of the State Architect.
Related provisions (CRSC sections)
- § 12-16-101 — Earthquake‑actuated automatic gas shutoff devices; adopt ANSI/ASCE/SEI 25‑16 for certification.
- § 12-16-101.1 — Installation of customer‑owned earthquake‑actuated devices must follow the California Plumbing Code (CCR Title 24, Part 5).
- § 12-16-201 — Residential excess‑flow valves; adopt ASTM F2138‑12(2017) and ANSI Z21.93‑2017/CSA 6.30‑2017 (up to 5 psig) for certification.
- § 12-16-201.1 — Installation of customer‑owned excess‑flow devices must follow the California Plumbing Code (CCR Title 24, Part 5).
If you need: I can extract the exact quoted lines of § 12-16-101 and § 12-16-201 for inclusion in a submittal or prepare a one‑page checklist to show a manufacturer/installer what to provide to the Division of the State Architect.

Frequently asked questions
What exact edition of the ASCE/ANSI standard does § 12-16-101 require?
The CRSC names ANSI/ASCE/SEI 25‑16 in § 12-16-101 as the applicable standard for certification. Confirm you are referencing the 2016 edition.
Does § 12-16-201 allow using only ASTM F2138 instead of the ANSI/CSA standard?
No — § 12-16-201 lists both ASTM F2138‑12(2017) and ANSI Z21.93‑2017/CSA 6.30‑2017 as the applicable standards used by the Division of the State Architect for certification. Use the standards cited by the section.
If my valve is rated at 6 psig, does the ANSI Z21.93/CSA 6.30 standard still apply?
The CRSC explicitly ties the ANSI Z21.93‑2017/CSA 6.30‑2017 reference to "with Pressure up to 5 psig" in § 12-16-201. For 6 psig you cannot rely on that pressure‑limited reference alone; you must review ASTM F2138 and consult the Division of the State Architect for the correct certification path.
Are installation rules included in the same sections as the certification rules?
The sections include installation direction: § 12-16-101.1 and § 12-16-201.1 require that each installation of a customer‑owned device that satisfies the standard shall be in accordance with the California Plumbing Code (CCR Title 24, Part 5).
Where can I find DSA’s procedural requirements for submitting a device for certification?
Procedural details (forms, lab accreditation, submission checklists) are not included in the retrieved CRSC text. Contact the Division of the State Architect or their program guidance for administrative steps.
