FS178-15	2603.7, 2603.7.1, 2603.7.2, 2603.7.3; IMC: 602.2.1.6, 602.2.1.6.1, 602.2.1.6.2, 602.2.1.6.3	Revises section 2603.7 “Foam plastic insulation used in plenums as interior finish or interior trim in plenums,” deletes without substitution section 2603.7.1 “Separation required,” deletes without substitution section 2603.7.2 “Approval,” deletes without substitution section 2603.7.3 “Covering,” revises section 602.2.1.6 IMC “Foam plastic insulation in plenums as interior finish or interior trim,” deletes without substitution section 602.2.1.6.1 “Separation required,” deletes without substitution 602.2.1.6.3 IMC “Covering,” and deletes without substitution section 602.2.1.6.2 IMC “Approval” to generate identical language in both the IBC and IMC code sections.  The code change was further modified by the Committee.  The modification keeps reference to compliance with Section 2603.9 as an alternative.  Also, the code change was further modified by public comment.  This public comment simply combines both proposals, as accepted by the technical committees and generates identical language into both code sections

Cost Impact: Will not increase the cost of construction. The proposal will potentially eliminate redundant testing to additional standards other than UL 723, ASTM E84, and NFPA 286.
