What are membrane penetration firestop systems and how has the penetration firestop standard evolved to evaluate them? The changes include a new section for definitions relating to the various types of membrane-penetrations, a description of the test setup for membrane-penetrations, and the conditions of acceptance for membrane-penetrations. For example, when a firestop system protecting a plumbing pipe penetrates the gypsum membrane on one side of a fire-resistance-rated gypsum wall, this revised standard would be used to evaluate that firestop system. Penetration Firestop System A through-penetration firestop or a membrane-penetration firestop.
