I am looking for any procedural guide on the proper way to test door force opening pressure. I would prefer a NFPA referenced standard but any would do at this point. The doors being tested are the stairwell egress doors, while the pressurization fan is on. We have the tool just need a procedure on how to use it. Thanks John

OHHH I am not an engineer, so you can discount my reply if you want, and I cannot do math.
