Re-test the completed opening because a compliant component can still produce a deficient doorway. ## Potentially affected Accessible-route doors and gates changed by electric locks, latch hardware, closers, hinges, weather seals, operators, power transfers, or frame work. ## DSE recommendation Measure force and closing behavior after the complete hardware set is installed and adjusted, with fire-rated and local-code requirements resolved by qualified authorities. ## Article Bottom line: an electric strike, maglock, door-position switch, cable transfer, new seal, or access-control timing change can alter how a door opens, closes, and latches. The finished assembly should be measured again rather than accepted from component submittals. ## Source fact: accessibility standards specify closing time and opening force Sections 404.2.8 and 404.2.9 of the [2010 ADA Standards — Closing Speed and Opening Force](https://www.access-board.gov/ada/chapter/ch04/#40428-closing-speed) address closing speed and opening force. The standards specify a minimum closer sweep time from 90 degrees to 12 degrees, a separate minimum time for spring hinges, and a maximum force for opening specified non-fire-rated interior hinged, sliding, and folding doors. The text includes exceptions and treats fire doors differently for force. These criteria apply to the opening in operation. A closer’s model rating or an installer setting is not the same as a measurement after every latch, seal, hinge, and access-control component is engaged. ## Source boundary and applicability The Access Board standard is an authoritative federal source, but the correct requirement depends on doorway type, accessible route, fire rating, referenced standards, local adoption, existing-facility status, and authority having jurisdiction. The cited force provision does not set a universal five-pound maximum for every door. This article is not legal or code advice. ## Applicability questions - Is the door fire-rated, on an accessible route, or part of required egress? - Which closer, hinge, latch, lock, seal, operator, and transfer device affect movement? - Does access authorization fully release the latch before the user applies force? - Are measurements being taken at the correct location, direction, and door state? - Can seasonal pressure, temperature, flooring, or building airflow change performance? ## DSE recommendation: make operational measurement a closeout requirement The following steps are DSE recommendations based on the cited source. Have qualified door, accessibility, and fire/life-safety personnel identify the applicable criteria and measurement method. After final access-control programming and complete hardware adjustment, measure opening force and closing behavior in all relevant operating modes. Verify authorization, latch release, manual operation, relatching, door-position monitoring, and any automatic operator together. If adjustment improves force but prevents reliable latching or required fire-door behavior, stop and resolve the system-level conflict; do not defeat a closer, latch, or rated assembly. Re-test after seasonal commissioning where pressure or weather produces material variation. ## Verification and evidence Retain the applicable-criteria determination, door and hardware schedule, instrument identification, method, measured values, access-control state, environmental conditions, deficiency and correction record, and qualified sign-off. Add remeasurement to change control for strikes, maglocks, closers, seals, hinges, operators, fire interfaces, and unlock timing. ## Official references - [2010 ADA Standards, Sections 404.2.8 and 404.2.9 — Closing Speed and Opening Force](https://www.access-board.gov/ada/chapter/ch04/#40428-closing-speed) – United States Access Board ## Primary reference - Name: 2010 ADA Standards, Sections 404.2.8 and 404.2.9 — Closing Speed and Opening Force - Authority: www.access-board.gov - URL: https://www.access-board.gov/ada/chapter/ch04/#40428-closing-speed - Source publication date: Not stated by the source ## Citation and use Preferred citation: “Re-measure door force and closing speed after every hardware change,” DSE Security, https://update.dsesecurity.com/updates/remeasure-door-force-and-closing-speed-after-hardware-change/ Publishing principles: https://update.dsesecurity.com/updates/dse-updates-editorial-methodology/ Usage and citation policy: https://update.dsesecurity.com/usage/ Copyright © 2026 Detection Systems & Engineering.
