Section 407.3.1 clearly defines the requirements for corridor doors in healthcare. It says "...shall provide an effective barrier to limit the transfer of smoke..."
Section 710.5.2 says "where required elsewhere in this code.....doors shall be tested in accordance with UL 1784 w/ artificial bottom seal...."
The only place in the code that I see another relative reference to the requirement for UL 1784 is 715.4.3 and 7184.108.40.206 which only applies to RATED corridor doors (20 min or greater) and smoke barriers.
1. Do you consider the statement in 407.3.1 listed above to be sufficient direction to lead you to section 710.5.2 thus requiring smoke seals and UL 1784 compliance for doors in smoke partitions.
