UL 962 Certification: What It Means for Office Pods

Short version: UL 962 is the North American safety standard for household and commercial furnishings that contain electrical parts — powered desks, illuminated furniture and, since its recent revisions, enclosed office pods and privacy booths. ClarityCastle’s Base-line pods (Solo, Meeting and Office sizes S, M and L) have been evaluated by UL Solutions to UL 962, Edition 5 (UL Certificate of Compliance UL-US-2585396-0, issued September 24, 2025).

What does UL 962 stand for?

UL 962 is the Standard for Household and Commercial Furnishings, published by UL Standards & Engagement and used for certification by UL Solutions. The current version is Edition 5, dated October 21, 2022, with its most recent revision and ANSI approval on June 18, 2025. UL’s furniture engineers say the standard dates back to the late 1990s; before the 2022 edition, the fourth edition from 2014 was in force.

“UL” itself is Underwriters Laboratories, founded in Chicago in 1894 by electrical engineer William Henry Merrill Jr. after he inspected the wiring at the 1893 World’s Columbian Exposition. In 2022 the organization split into three bodies: UL Solutions (testing and certification), UL Standards & Engagement (writes the standards) and UL Research Institutes.

What UL 962 covers

The standard applies to furnishings rated 600 V AC or less that contain electrical components. Its scope includes motor-operated furniture, electrified and non-electrified furniture, home-office furnishings, commercial tables and work surfaces, electrified building components such as illuminated mirrors and — most relevant here — enclosed rooms and pods. It excludes patient-care products (UL 60601-1), portable lamps (UL 153) and infant products, which have their own standards.

UL describes UL 962 as covering three families of hazard: electrical, flammability and personal injury. In practice, a UL 962 evaluation looks at:

Electrical safety of the integrated wiring, receptacles, luminaires, power supplies and any HVAC or fan equipment, including the cord-and-plug connection or the junction box for permanent wiring.
Stability and mechanical strength — the unit must not tip, and ceilings, desks and seating are load-tested.
Fire performance of materials — panels, fabrics, laminates and adhesives are evaluated for flame-spread and smoke-developed indices using UL 723 (the same test behind ASTM E84 “Class A” ratings). For rooms, the maximum flame-spread index is 200 and the maximum smoke-developed index is 450; a product over the smoke limit must be marked accordingly.

Why the recent revisions matter for office pods specifically

In its 2021–2022 revisions UL added requirements to UL 962 written specifically for “prefabricated privacy booths and sleep capsules” — the product category ClarityCastle sells. Among the additions UL has published:

Doors must swing outward or slide, and any lock must be openable from both sides — nobody can be locked inside.
Pods need a fire-suppression strategy: an open-grid ceiling that lets the building’s sprinklers reach inside (with 18–36 inches of clearance depending on sprinkler type and layout), a listed drop-out ceiling, or a self-contained suppression system.
Integrated wiring, outlets, lighting and ventilation are evaluated as part of the whole product rather than piece by piece.

UL’s reasoning is simple: a pod that arrives fully built bypasses the permit-and-inspection process that a built wall would go through, so the code authority cannot see the concealed wiring. A third-party listing is the substitute. In UL’s own words, certification “demonstrates compliance with model installation codes and may result in faster inspections.”

That connects to two rules facility teams already live with. OSHA’s 29 CFR 1910.303(a) requires workplace electrical equipment to be “approved,” which OSHA interprets as certified by a Nationally Recognized Testing Laboratory. And NEC 110.3(B) requires listed equipment to be installed according to its listing instructions — the item an Authority Having Jurisdiction (AHJ) checks first.

ClarityCastle's UL 962 evaluation

Representative samples of our Base-line pods — product designation “Rooms,” models S, M and L — were evaluated by UL under product category IYNE (Furniture, Powered and Nonpowered) against UL 962, Edition 5. Those three models map to our Solo phone booth, our private office pods and our meeting room pods.

A note on wording, because it matters to inspectors: a Certificate of Compliance confirms that representative samples met UL’s requirements. The right to apply the UL Mark to each unit comes from UL’s Follow-Up Services program, which is a separate, ongoing surveillance agreement with the factory. If your project’s AHJ requires the mark on the unit itself, tell us up front and we will document exactly what ships on your pod.

UL Product iQ — the free database at productiq.ulprospector.com lets you search by file number (E546110), category code (IYNE) or model. AHJs get upgraded access, including confirmation letters.
Look at the unit — UL says code officials should look for the UL Certification (Listing) Mark on the product.

UL Listed vs. UL Recognized vs. ETL

You will see several marks on pods in the market. UL Listed / UL Certified means the complete end product was tested to a standard. UL Recognized applies to components (a power supply, a fan) that are meant to be built into a larger certified product — it is not a listing for the pod itself. ETL is the mark of Intertek, a different NRTL that tests to the same UL 962 standard; AHJs in all 50 states accept it. What matters is the standard number and that the whole pod, not just its parts, was evaluated.

Fun facts

UL’s first test report was signed on March 24, 1894, in a lab above a fire-insurance patrol station in Chicago, with $350 worth of equipment and two employees.
UL’s first published standard, in 1903, was for tin-clad fire doors. Today UL Standards & Engagement maintains more than 1,700 standards and documents.
The Standard Time-Temperature Curve that fire labs worldwide still use to rate walls and doors came out of UL’s 1917–1919 column fire research and became a U.S. standard in 1920.
UL 962 has a sibling, UL 962A, that covers furniture power distribution units — the cord-and-plug power strips built into desks.

Frequently asked questions

Is UL 962 required by law?

UL 962 is a voluntary standard, but the rules that reference NRTL-certified electrical equipment — OSHA 1910.303 and NEC 110.3 — are not. In commercial buildings, an uncertified powered pod can be flagged at inspection, and UL notes the alternative is a paid Field Evaluation of the installed unit.

Does UL 962 replace local fire code?

No. UL says code authorities should still be consulted about local requirements, and some AHJs require sprinkler coverage inside every pod regardless of listing. See our office pod questions page for how we handle sprinkler clearance on installs.

Does UL 962 say anything about acoustics or air quality?

No. Acoustic performance is tested separately (our figure is ~30 dB speech-level reduction, tested to ASTM C423) and chemical emissions fall under programs such as GREENGUARD Gold.
