Before any elevator, escalator, or automated material-handling system can legally carry a patient, a staff member, or a specimen in a U.S. hospital, it must pass a formal sequence of acceptance tests, be inspected and witnessed by the authority having jurisdiction (AHJ), and receive a state or local operating certificate. This Article covers that gauntlet — the code-mandated tests, who runs and witnesses them, the inspection and certification mechanics, and the documentation that proves a unit is safe to operate — distinct from the broader operational readiness and owner-handover activities covered by the sibling Article on activation readiness and handover.

Why VT certification is a hard gate, not a punch-list item

Vertical transport is one of the few building systems that cannot be quietly turned over with open items. An elevator or escalator that has not passed acceptance testing and received its operating certificate may not legally be placed in service for public or patient use. In a hospital this is doubly consequential:

• Life-safety dependency. Elevators are integral to the building's fire-protection and egress strategy — firefighters' emergency operation (Phase I recall / Phase II in-car operation), occupant-evacuation elevators where provided, fire-service access, smoke-control interlocks, and emergency-power transfer all run through the elevator controller. A failed VT acceptance test is frequently also a failed life-safety interface, which can block the building's certificate of occupancy.
• Clinical-flow dependency. Patient/stretcher elevators, service cars, pneumatic tube, and AGV systems are the circulatory system of a multi-story hospital. An uncertified bank of cars means a tower floor cannot accept patients, a surgical suite cannot be supplied, and a pharmacy cannot move STAT medications.

Because certification is a true gate, the VT testing-and-certification milestone belongs on the project critical path and on the activation timeline — not in the general commissioning backlog. The AHJ's witnessed inspection date, the certificate issuance lead time, and any re-inspection cycle are schedule risks that an owner/PMO should track explicitly.

The governing codes and who the AHJ is

VT acceptance testing in the United States is governed primarily by the ASME A17.1 / CSA B44, Safety Code for Elevators and Escalators, which most states and cities adopt by reference (often with state amendments and a specified edition). Companion and intersecting standards include:

• ASME A17.1 / CSA B44 — the core safety code; defines acceptance-test requirements for new installations and the periodic/category tests thereafter.
• ASME A17.2, Guide for Inspection of Elevators, Escalators, and Moving Walks — the inspector's procedural manual that operationalizes how A17.1 tests are actually performed and witnessed.
• ASME A17.3 — safety code for existing elevators (relevant on renovation/modernization scopes).
• ASME A18.1 — Safety Standard for Platform Lifts and Stairway Chairlifts (LULA elevators, platform lifts — common in clinics and smaller facilities).
• IBC (International Building Code) — elevator hoistway, machine room, fire-service access elevators, occupant-evacuation operation, and the building-level requirements that the elevator must satisfy as part of the egress/fire strategy.
• NFPA 72, National Fire Alarm and Signaling Code — the fire-alarm initiating devices (lobby/hoistway/machine-room smoke and heat detectors) that drive Phase I recall; the elevator-recall interface is tested jointly with the fire-alarm acceptance test.
• NFPA 70 (NEC), Article 620 — wiring, controls, and disconnects for elevators, dumbwaiters, escalators, moving walks, and platform lifts; NEC Article 700/701/708 and NFPA 110 for the emergency/standby power source feeding the cars; NEC Article 517 for health-care electrical systems generally.
• NFPA 101 (Life Safety Code) / NFPA 99 (Health Care Facilities Code) — elevator life-safety interfaces, and (for the building) the broader egress and essential-electrical-system requirements that the elevator participates in.
• ADA / ICC A117.1 — accessibility: car size, door timing, leveling tolerance, control heights, audible/visual signals, and door reopening — verified at acceptance.
• ASHRAE 170 and the FGI Guidelines — sit upstream of VT in design (clearances, finishes, ventilation of machine rooms) but inform what an inspector or surveyor will scrutinize in a clinical context.

Who the AHJ is varies by jurisdiction and is the single most important thing to confirm early on a project:

• In most states, an elevator inspection authority sits within a state department (Labor, or Buildings/Construction) or with the municipality. The AHJ may employ its own inspectors or accept inspection by a QEI-certified (Qualified Elevator Inspector, certified under ASME QEI-1) third party whose report the state then uses to issue the certificate.
