Medical gas certification means ASSE 6010 — the Medical Gas Systems Installers credential in the ASSE/IAPMO/ANSI Series 6000, whose 2024 edition parallels NFPA 99-2024.
You earn it through a certification body such as NITC and renew it every three years; your state can add an endorsement of its own on top.
ASSE does not publish the 6010 course hours or exam format publicly, so this page separates what is verified from what only the standard and your state board confirm.
What is ASSE 6010 medical gas certification?
ASSE 6010 is the credential standard for Medical Gas Systems Installers — the tradespeople who install the piped medical gas systems in hospitals, clinics and other health-care facilities.
It is one standard in the ASSE/IAPMO/ANSI Series 6000, whose 2024 edition parallels NFPA 99-2024, the edition of the Health Care Facilities Code the series is aligned with.
The installer credential sits inside a family of separate roles.
The 2024 series defines 6005 generalist, 6015 cryogenic installer, 6020 inspector, 6030 verifier, 6035 cryogenic verifier, 6040 maintenance, 6050 and 6055 instructors, 6060 designer, and 6070 design instructor — each its own credential.
Inspectors and verifiers (ASSE 6020 and 6030) are their own track, and this page stays on the installer role.
One thing to know before you plan around it: the ASSE 6000 standard text is a paid document, and ASSE's public pages do not publish the 6010 course hours, exam format or experience prerequisites, so our research could not verify them.
What the public record does show is the credential's role in the system — it is the layer state medical gas rules are written around.
Alabama's endorsement requires ASSE 6010 by name, and Kansas requires the appropriate ASSE Series 6000 certification for medical gas piping work.
Who can take the ASSE 6010 certification?
The straight answer: ASSE/IAPMO's public pages do not publish the experience prerequisites for 6010 — the standard text is sold, not posted — so our research cannot confirm them, and neither should anyone quoting a specific years-of-experience rule from memory.
Confirm current prerequisites, training and exam arrangements with ASSE International or a certification body such as NITC before you plan around a particular requirement.
What the state rules do show is who ends up holding the credential: people already in the licensed pipe trades.
Alabama's medical gas piping endorsement requires a current third-party ASSE 6010 installer certification plus an apprentice, journeyman or master credential from the Alabama Plumbers and Gas Fitters Examining Board (PGFB).
Georgia issues its Statewide Medical Gas Piping Certification to licensed master or journeyman plumbers.
Iowa requires a separate board-approved certification to install or repair medical gas piping, with applicants needing a valid NITC (or equivalent) certification.
New Jersey's certification for medical gas piping work is open to licensed masters, journeymen who completed a USDOL apprenticeship, and apprentices with 3+ years.
The practical read: med gas installation is institutional pipe work, close kin to a pipefitter career, so the usual base is a plumbing licence or an active apprenticeship in a licensed state, with the 6010 credential added on top of it.
Where licensing is local rather than statewide, your city or county sets that base licence.
Prerequisites: confirm with the certifying body, not a forum
The course and the brazing test
The gap first: ASSE does not publish the 6010 course structure on its public pages — the standard that defines it is a paid document — so no hour total for ASSE 6010 itself can be confirmed here.
What the public record does show, in exact numbers, is what states require in their own medical gas programs.
Those are the figures you can plan around.
Read those rules side by side and the shape is consistent, even where the stated basis differs: Georgia's program is built on the ASSE 6000 series and NFPA 99, Texas's classroom hours on NFPA 99, and Florida's course on NFPA 99C.
Purging and brazing get tested shop time of their own — Texas writes at least 4 hours of shop work on assembly, purging and brazing into its requirement, and Georgia runs a braze test as part of its program.
And the requirement does not always stop at the initial credential: Georgia requires holders to braze at least once every 12 months.
Note that each of these hour totals belongs to that state's program, not to ASSE 6010 itself — a provider advertising a specific course length is quoting its own course, so ask what it certifies you for.
What the state programs require
Renewing medical gas certification
ASSE certifications must be renewed every three years, and recertifying up to six months early loses no time.
That is the certifying body's cycle, and it applies to the 6010 credential the same way it does across the ASSE series.
The state layer renews on its own terms, and it can attach work the ASSE cycle does not.
New Jersey's medical gas piping installer certification renews every three years for $150, with the initial certification also $150 in the first year of the triennial cycle.
Texas endorsements renew every three years, and the Medical Gas endorsement requires at least 2 hours of CPE to renew.
Georgia's rule that holders braze at least once every 12 months is a recency condition on top.
Louisiana's Medical Gas installer and verifier licences must recertify each NFPA 99 code cycle under the ASSE 6000-series standards.
Minnesota issues medical gas certifications with 4 CE hours per licence period.
So plan two calendars: the certifying body's three-year recertification, and whatever your state board attaches to the endorsement — CE or CPE hours, a practical recency requirement, or a recert on the code cycle.
Confirm both with the bodies that issued your credential and your endorsement.
Where medical gas certification is legally required
Two layers decide this.
The code layer is NFPA 99, the Health Care Facilities Code — the ASSE Series 6000-2024 is aligned with its medical gas requirements.
Edition matters: NFPA lists 2027 as the current edition of NFPA 99, but Medicare-participating hospitals must follow the 2012 edition, as incorporated by CMS in 42 CFR 482.41, and states may adopt other editions.
Which edition governs your project is a question for the authority having jurisdiction, not for a career guide.
The licence layer is state law, and it is where the certification becomes mandatory.
Two of the states our research covers write the ASSE credential straight into their rules: Alabama's medical gas piping endorsement requires a current third-party ASSE 6010 installer certification, and Kansas allows medical gas piping to be installed only by a plumber licensed under its state standards who also holds the appropriate ASSE Series 6000 certification.
Others run their own program instead of naming ASSE: Iowa requires a separate board-approved certification, with a valid NITC (or equivalent) certification; Oklahoma treats medical gas as a mechanical — not plumbing — journeyman category requiring certification under the current NFPA 99 standard or an approved medical gas certification; New Jersey requires a separate Master Plumbers Board certification for medical gas work in health-care, dental and veterinary facilities; Montana offers a Medical Gas Endorsement for plumbers requiring proof of completing a board-approved training program; and Louisiana issues Medical Gas installer and Medical Gas Verifier licences through the State Plumbing Board of Louisiana (SPBLA).
Read the list for what it is — the states our research covers, each rule that state's own.
A state absent from it is not a state with no requirement; our research simply did not confirm one.
The authority that says what your job requires is your state licensing board, or the city or county where licensing is local.
Once the credential and endorsement are on your licence, the work shows up in plumber jobs at hospital contractors and mechanical shops.
