Steps
When recommending or replacing a door closer, reference ANSI/BHMA A156.4, which sets cycle-testing and performance grades, with Grade 1 the baseline for demanding commercial/institutional traffic and lower grades intended for lighter-duty use.
Match the closer grade to the door's actual traffic and duty cycle rather than defaulting to the cheapest option, especially on doors code officials are likely to inspect.
If the door is part of a fire-rated assembly, confirm the specific closer model is listed for use on that rated assembly, not just A156.4 graded in general, before installing or swapping it.
Adjust closing force, latching speed, and sweep per the manufacturer's instructions and any applicable accessibility requirements, such as reduced opening force where required, rather than adjusting by feel.
Verify the currently active edition of A156.4 before citing specific numeric test thresholds to a customer, since BHMA standards are periodically revised.
Known gotchas
A156.4 grading and fire-door listing are two different approvals; a Grade 1 closer isn't automatically approved for a specific fire-rated door assembly unless it's also listed for that use.
Adjusting a closer's closing force to satisfy occupant complaints can inadvertently violate accessibility opening-force limits; check both code angles before finalizing an adjustment.
