How to look up specific plumbing/product standards (NSF, CSA, ASME) in Chapter 6

Q: How do I confirm which edition/year of a standard CALGreen references?

Check the Chapter 6 table entry under § 601.1 — the table lists the standard number and, where provided, the edition or year used by the code. If the edition is not clear, check the requiring section or local adoption notes. file

CALGreen **§ 601.1** is an index: it lists NSF, CSA, ASME (and other) standards and shows the code sections that require them. Use § 601.1 to find the exact standard (and edition) and the “Referenced Section” column to jump to the section that contains the enforceable requirement (flow rates, certifications, test methods). If a standard is listed only as informational or not locally adopted, confirm local adoption before relying on it. file

What the code requires

Chapter 6 is the CALGreen Referenced Organizations and Standards chapter; § 601.1 says the chapter “lists the organizations and standards that are referenced in various sections of this document” and that standards are listed according to the promulgating agency. § 601.1 therefore is the index: it does not contain product performance numbers — it tells you which standard applies and where in the code that standard is required.

The single most important rule: use § 601.1 to find the standard name/acronym and the CALGreen (or other code) section that requires it — then read that requiring section for the actual performance or certification requirement.

Key defined terms (first mention)

§ 601.1 — the Chapter‑6 index of referenced standards (CALGreen).
Referenced Standard — the named standard (for example, NSF/ANSI, CSA, ASME entries) shown in Chapter 6 and paired with the CALGreen section(s) that use it.

Requirements in detail

Steps to look up a plumbing/product standard in CALGreen Chapter 6 (practical workflow)

Open Chapter 6 (Referenced Organizations and Standards) and locate § 601.1 — this is the table that lists standard acronyms/numbers and the CALGreen sections that reference them.
Find the standard acronym or number you need (e.g., NSF, CSA, ASME A112.x). The table’s “Referenced Section” column tells you which CALGreen (or other) code section requires that standard.
Go to the CALGreen section shown in the “Referenced Section” column (or to the referenced technical code section, e.g., Plumbing Code) and read that section to learn the actual requirement (flow rate, certification, installation rule, etc.). Note: Chapter 6 itself is an index; performance or certification details live in the sections that call the standard.
If the referenced section points to a technical code (plumbing, mechanical, etc.), open that code and read the specific product/fixture requirement (the technical code contains the normative test, flow rate, or certification reference). Example: faucets are required to comply with ASME A112.18.1/CSA B125.1 in the Plumbing Code section covering faucets.

Decision-relevant checklist (quick table)

Decision question	How to use Chapter 6 to answer it	Code Reference
Which standard covers my product (NSF / CSA / ASME)?	Look up the standard acronym or number in the Chapter 6 table under § 601.1.	§ 601.1
Where in the code is that standard required?	Read the “Referenced Section” column next to the standard entry in the table — it points to the section that requires the standard.	§ 601.1
Does Chapter 6 itself set numeric limits (e.g., gpm)?	No — Chapter 6 is an index. Go to the referenced CALGreen/plumbing section it points to for numeric values (e.g., flow rates).
Is the referenced standard automatically part of the enforceable code?	Not always. Some referenced standards are included for convenience and may not be part of the code unless adopted by the local jurisdiction — check Chapter 8 notes and local adoption.

How Chapter 6 is organized (what to expect)

The table in § 601.1 lists the standard acronym/number, the standard title, and the Referenced Section where the standard is required. Use the row for NSF, CSA, or ASME to see the exact standard number and where it’s used.
Standards are grouped by the issuing organization (NSF entries together, ASME entries together, etc.).

Exceptions & special cases

Informational-only entries: CALGreen sometimes includes referenced standards “for convenience” and notes that they are not part of the code unless adopted by a local jurisdiction — confirm local adoption before relying on an informational standard.
Multiple editions: Chapter 6 typically lists a specific edition/year for a referenced standard. If you need a different edition, verify whether the code text that references the standard permits later editions or explicitly fixes the edition. The Chapter 6 table shows the edition where provided.
Cross-code calls: CALGreen may list a standard that is used by another technical code (e.g., Plumbing Code). The chapter’s “Referenced Section” may point you to the plumbing code section number — you must read that plumbing code section to get the performance requirement or installation detail. file

Common mistakes

Assuming Chapter 6 contains the technical requirement. False — § 601.1 is an index; it only lists standards and where they’re referenced. Always follow the referenced (requiring) section for the actual rule.
Skipping local adoption checks. Some standards listed in CALGreen are informational until a jurisdiction adopts them — check Chapter 8 and the local adopting authority.
Confusing acronym search with exact standard number. If you search just “ASME” you may miss that the code actually requires ASME A112.18.1 (a specific ASME standard). Use the precise standard number from § 601.1 to find the right requirement.
Not following cross-references. If § 601.1 points to a Plumbing Code section (for example § 417.1 for faucet fittings), read that plumbing section — it contains the compliance language and any numeric limits.

Worked example — concrete scenario

Scenario: You are specifying a public lavatory faucet and need to confirm which standard(s) it must meet.

Search Chapter 6 (§ 601.1) for “ASME A112.18.1” or the acronym “ASME.” The Chapter 6 table will show the standard entry and list the CALGreen or other code section that references it.
The table entry for ASME A112.18.1 will point to the requiring section; for faucets CALGreen points you to the plumbing/fixture requirement (CALGreen/Plumbing Code reference). For example, the Plumbing Code’s faucet/fixture section § 417.1 states that “Faucets and fixture fittings shall comply with ASME A112.18.1/CSA B125.1.” Read § 417.1 for the compliance statement.
If you also need a numeric flow rate (for a kitchen or public lavatory), the Plumbing Code or CALGreen water‑efficiency section will contain the gpm limits (e.g., kitchen faucet default to 1.8 gpm in applicable CALGreen/Plumbing provisions) — but that numeric value is in the requiring section, not in § 601.1. Confirm the exact numeric value and any default behavior from the requiring section (see the plumbing code example for kitchen faucet flow-rate language).

Numbers in the example above (like 1.8 gpm) are found in the requiring plumbing/CALGreen sections — § 601.1 only tells you where to look. file

Related provisions

§ 601.1 — Chapter 6 table of referenced organizations and standards (the index you must use).
Chapter 5, Division 5.3 — Water efficiency / appliance performance cross-references often called by plumbing sections (see table of contents and chapter headings).
Chapter 8 notes on referenced standards (explains informational vs. adopted standards).
Plumbing Code sections that implement the standards referenced in Chapter 6 (examples: § 417.1 for faucets; § 420.2 for sink/kitchen faucet flow limits) — those are the sections you will be directed to from § 601.1. file
