This webinar will provide an overview of criteria that can be used to demonstrate the equivalence of alternatives to the ½-inch gypsum or 5/8-inch wood structural panel membrane that is required by Act 1 of 2011. This act eliminated sprinkler requirements, but required a protective floor membrane, the installation of which comes with its own set of challenges. This requirement has driven many builders to seek alternatives, which in turn has caused many code officials to struggle with approval. This webinar, which is an update and re-delivery of a previous PHRC webinar, will clarify acceptable paths for demonstrating equivalence, will explore acceptable testing procedures that determine equivalence, and will provide an overview of applicable portions of Act 1 of 2011 and ASTM E 119 – Standard Test Methods for Fire Tests of Building Construction and Materials. The webinar will also explore changes/updates to demonstrating compliance using AC14 - Acceptance Criteria for Prefabricated Wood I-Joists.

Learning Objectives

Following completion of this webinar, participants will be able to:

• Understand what testing procedures are used and accepted when determining equivalence related to the International Building Code‘s defined burn times of ½ inch drywall

• Explain the portions of Pennsylvania’s Act 1 of 2011 that relate to the elimination of the 2009 IRC’s required fire sprinkler systems, as well as, the requirement of protection of residential floor systems against flame spread

• Evaluate the literature of AC 14 (Acceptance Criteria for Prefabricated Wood I-Joists) to determine required the burn times associated nominal 2 x 10 joists and how that relates to determining equivalency to prefabricated wood I-joists

• Compare ASTM tests that are commonly used for fire related testing and what variable each test is attempting to determine
