Door Closers ANSI & EN
Supplied by
About
- Door closers certified to both ANSI/BHMA A156.4 and EN 1154, covering surface, concealed and floor-spring types with the mounting templates for either standard. One product line then serves openings drawn to either code without a second set of fixing centres on site.
Application
Chosen on projects with mixed specifications, on operator-branded fit-outs inside a locally designed building, and by facilities teams standardising a spares holding across a portfolio built to different codes. Dual certification also simplifies approval where the authority having jurisdiction accepts either standard but wants a single documented basis for the whole schedule.
Standards & Reference 6 cited
ANSI/BHMA A156.4
Door controls: closers, graded by cycle testing. Grade 1 is the specification for high-traffic and fire-rated openings.
EN 1154
Controlled door closing devices: closer power size, and the closing behaviour a fire door depends on to latch every time.
EN 1155
Electrically powered hold-open devices for swing doors: how a fire door is legitimately held open and released on alarm.
UL 10C
The positive pressure fire test for door assemblies. Positive pressure drives hot gas through any gap between door and frame, which makes it the more demanding test and the one North American codes now call for.
NFPA 80
Not a test but a compliance standard: how fire doors are installed, inspected and maintained, including the annual inspection and the requirement that every fire door self-closes and positively latches.
EN 1634-1
The European fire resistance test for door and shutter assemblies, and the basis for CE marking a fire door. Built on a different pressure regime from UL 10C, so the two ratings are not interchangeable.
