Where is NSF/ANSI 140 (carpet sustainability) cited in CALGreen?
For homeowners: CALGreen requires interior carpet and carpet cushion to meet the California Department of Public Health emissions test (Spec 01350) per § 4.504.3. NSF/ANSI 140 (carpet sustainability) is listed in the code’s referenced-standards table and is accepted as a voluntary option (Gold level) in the health-facility appendix, but it is not the mandatory emissions test in § 4.504.3.
Last reviewed: July 6, 2026
What the code requires — plain English
- The mandatory CALGreen rule for carpet systems in Chapter 4 is § 4.504.3: carpet (and carpet cushion) installed inside buildings must meet the California Department of Public Health (CDPH) emission testing method (California Specification 01350) — NOT NSF/ANSI 140 as the primary mandatory test in that section.
- Separately, NSF/ANSI 140-2014 (Sustainability Assessment for Carpet) is listed in CALGreen’s Referenced Standards pointing to § 4.504.3, and appears as an accepted option in the voluntary health‑facilities appendix (NSF/ANSI 140 at the Gold level).
The controlling mandatory requirement for carpet emissions is § 4.504.3 (CDPH Specification 01350); NSF/ANSI 140 shows up in the referenced-standards list for § 4.504.3 and as an accepted voluntary option in Appendix A for health facilities.
Requirements in detail
Mandatory chapter requirement (residential/nonresidential finish-material control)
§ 4.504.3 Carpet systems — All carpet installed in the building interior must meet the CDPH “Standard Method for the Testing and Evaluation of Volatile Organic Chemical Emissions from Indoor Sources Using Environmental Chambers,” Version 1.2 (California Specification 01350). Verification URL is referenced in the code text.
§ 4.504.3.1 Carpet cushion — Carpet cushion must also meet CDPH Specification 01350.
§ 4.504.3.2 Carpet adhesive — Carpet adhesives must comply with the limits shown in Table 4.504.1 (VOC limits table).
Where NSF/ANSI 140 appears in CALGreen
Referenced-standards list: NSF/ANSI 140-2014 (Sustainability Assessment for Carpet) is listed as a referenced standard and the table entry points to § 4.504.3 as the section that cites it. That establishes NSF/ANSI 140 as a recognized standard in the CALGreen references for carpet.
Appendix A (voluntary health-facility guidance): A6.504.8.4 Carpet systems explicitly lists acceptable carpet testing/product programs for interior installations; item 3 is NSF/ANSI 140 at the Gold level (along with Green Label Plus, CDPH 01350 and others) — this is a voluntary / appendix acceptance for health facilities.
Decision-relevant checklist (quick table)
| Decision factor | CALGreen requirement / value | Code reference |
|---|---|---|
| Mandatory emissions test for carpet (interior) | CDPH Spec 01350 (emission testing), required | § 4.504.3 |
| Mandatory emissions test for carpet cushion | CDPH Spec 01350 | § 4.504.3.1 0 |
| Carpet adhesive requirement | Meet Table 4.504.1 VOC limits | § 4.504.3.2 |
| NSF/ANSI 140 presence in code | Listed in Referenced Standards pointing to § 4.504.3 (NSF/ANSI 140‑2014) | Referenced standards table — § 4.504.3 (entry) |
| Where NSF/ANSI 140 is accepted as an option | Appendix A (voluntary health‑facility guidance): NSF/ANSI 140 (Gold level) listed as an accepted program for carpet systems | § A6.504.8.4 |
| Primary controlling mandatory spec for carpet VOCs | CDPH “Standard Method… Version 1.2, Jan 2017” (California Spec 01350) | § 4.504.3 |
(Use the CDPH site link in the code text for certification/testing lab information.)
Exceptions & special cases
If you are working under Appendix A (voluntary / health‑facility guidance) rather than the mandatory Chapter 4 provisions, NSF/ANSI 140 (Gold) is explicitly accepted there as one of several acceptable programs for interior carpet — but Appendix A is voluntary and applies to the listed OSHPD health‑facility contexts. This does not change the mandatory requirement in § 4.504.3, which specifies CDPH Spec 01350 for mandatory compliance.
The Referenced Standards table lists many standards; an appearance in the referenced list does not itself override the specific text of the controlling mandatory section — you must follow the mandatory text in § 4.504.3 unless an authority adopts the appendix or otherwise permits an alternate compliance path.
Common mistakes
- Assuming that because NSF/ANSI 140 is in the referenced-standards table for § 4.504.3, it is the mandatory test for carpet. That is incorrect — § 4.504.3 itself requires CDPH Specification 01350 for mandatory carpet emission testing.
- Confusing Appendix A voluntary options (health‑facility guidance) with mandatory Chapter 4 requirements. Appendix A lists NSF/ANSI 140 Gold as an option for certain voluntary health‑facility measures — it does not replace the mandatory text of § 4.504.3.
- Forgetting to verify carpet cushion separately — § 4.504.3.1 requires cushion to meet CDPH Spec 01350 as well.
Worked example — applying the rule
Scenario: You are specifying carpet for a 10,000 ft² office interior (mandatory Chapter 4 obligations apply).
- The code requires the carpet product to meet CDPH Spec 01350 emissions testing per § 4.504.3 — so obtain a product certification/report showing compliance to CDPH 01350 (emissions chamber testing, Version 1.2).
- The carpet cushion must also meet CDPH Spec 01350 per § 4.504.3.1 — confirm cushion documentation separately.
- Any carpet adhesive used must conform to the VOC limits found in Table 4.504.1 as required by § 4.504.3.2 — check the adhesive technical data sheet and invoice.
- Although NSF/ANSI 140 (Gold) is listed in the Referenced Standards for § 4.504.3 and is an accepted voluntary option in the health‑facility appendix, unless your project is using that Appendix A voluntary pathway (e.g., specific OSHPD health‑facility guidance), the mandatory path is CDPH 01350. If you are in a health‑facility project using voluntary Appendix A measures, NSF/ANSI 140 (Gold) can be accepted per A6.504.8.4.
Related provisions (CALGreen sections)
- § 4.504.3 — Carpet systems; mandatory CDPH emission testing requirement (California Spec 01350).
- § 4.504.3.1 — Carpet cushion; CDPH Spec 01350 required.
- § 4.504.3.2 — Carpet adhesive; see Table 4.504.1 VOC limits.
- § 4.504.4 — Resilient flooring emissions threshold (related low‑emitting flooring requirements).
- § A6.504.8.4 — Appendix A voluntary guidance (health facilities): lists acceptable carpet programs including NSF/ANSI 140 (Gold).
- Referenced Standards table entry: NSF/ANSI 140‑2014 is listed as associated with § 4.504.3 in the standards table.

SINGLE-FAMILY RESIDENTIAL BUILDINGS— MANDATORY FEATURES AND DEVICES
Frequently asked questions
Is NSF/ANSI 140 the mandatory carpet standard in CALGreen?
No. The mandatory requirement in § 4.504.3 is CDPH Specification 01350 (emissions testing). NSF/ANSI 140 appears in the referenced standards table and as a voluntary Appendix A option for health facilities, but it is not the mandatory emissions test in § 4.504.3.
Where in CALGreen is NSF/ANSI 140 explicitly accepted?
NSF/ANSI 140 (Gold level) is explicitly listed as an accepted program for carpet systems in Appendix A — A6.504.8.4 (voluntary health‑facility guidance).
If a product is NSF/ANSI 140 Gold certified, does it automatically comply with § 4.504.3?
Not automatically. § 4.504.3 requires CDPH Spec 01350 for mandatory compliance. NSF/ANSI 140 Gold is a separate sustainability certification and appears as an appendix-accepted option for certain voluntary health‑facility measures; you still must meet the mandatory requirements in the controlling text unless your adopting authority accepts the appendix option.
What documentation should I collect for inspections?
For mandatory compliance under § 4.504.3 collect product certification or laboratory reports showing compliance with CDPH Spec 01350 for carpet and cushion, and product data/invoices showing adhesive VOC compliance to Table 4.504.1. Appendix A suggests verification methods (manufacturer’s product spec, field verification) for voluntary programs.
