1. Scope 1.1 This test method covers testing procedures for through penetration firestop systems. This test method is intended for the following uses: 1.1.1 To determine relative movement capability in two separate and distinct planes of movement for different types of firestop systems, 1.1.2 To standardize a comparison of movement capability by establishing test parameters that fix most test parameters to standardized values, in order to allow variables of interest (i.e. type of firestop system) to be examined as the sole variable , 1.1.3 To provide the user with information on amplitudes of relative movement between the penetrating items and substrate (wall or floor assembly) penetrated. 1.2 This test method is intended to be used only as part of a specification or acceptance criteria due to the limited movements tested.
Penetration firestop systems have been tested in accordance with ASTM E814 for 20 years or more. UL, just one agency listing penetration firestop systems, has over 7000 systems listed based on fire testing to UL1479 (ULs functional equivalent to E814). Installers and building owners have over the years asked questions about the impact of penetrating movement on these installed firestop systems. The fire tests (E814, UL1479) do not address movement, as they require the penetrating item to be rigidly supported on both sides of the test assembly. This test standard would provide a standardized method to start answering some of the questions regarding the ability of installed firestop systems to experience some degree of movement and continue to be relied upon to perform their firestopping function. This standard will not answer all questions related to movement. However, starting from a zero knowledge base, it can at least begin to quantify how much movement an installed and fully cured (if applicable) firestop system can withstand before some degree of damage occurs that will place the firestopping ability of the firestop system into question. The test provides a simplified and standardized test arrangement, as the greatest need at this time is to develop a growing knowledge base to understand how many of the 7000+ systems already tested and listed over the past two decades would be expected to perform if the penetrating item is moved for a given amplitude in a given direction. The standard would be used by firestop product manufacturers and testing laboratories to determine how much movement different firestop systems could withstand before their fire resistance rating is questioned. The results of the test could be used by specifiers, designers and installers to aid in the selection of suitable firestop systems based on the degree of expected movement of the penetrating item over the life of the building.
