ASTM E3157-22

1.1 This guide is a compendium of information related to installing firestop systems in fire-separating elements. This guide is intended to be used to increase industry knowledge of national and international testing requirements, code prerequisites, and other supplemental tests that may be specified, which can affect the installation and performance of firestop systems.

1.2 This guide relates to the use of firestop systems tested, or evaluated, to Test Method E814 and other test methods addressing the same specific subject matter, such as CAN/ULC-S115; EN 1366-3; IMO Resolution MSC.307(88), FTP Code; IEEE 634; ISO 10295-1; UL 1479; etc.

1.3 This guide also addresses the use of firestop systems tested or evaluated to Test Methods E119 or other test methods that use a firestop system as a component of a typically larger test assembly, such as AS 1530.4; BS 476-21; BS 476;3 CAN/ULC-S101; ISO 834;4 NFPA 251; UL 263; etc.

1.4 This guide discusses the installation of firestop systems in membrane penetrations and through penetrations. The installation is typically performed by a firestop contractor (also known as a firestop installer or an installer). However, the quality of the installation is based on the information provided to the firestop contractor as well as the expertise and competence of the firestop contractor. A lack of information in the test report, listing, manufacturer''s instructions, or project documents can be the cause of a deficient installation.

1.5 The term "firestop system" refers to and includes both a membrane-penetration firestop system and through-penetration firestop system.

1.6 Information in this guide is applicable to firestop systems that accommodate single or multiple penetrating items.

1.7 This guide does not address the design aspects of locating and defining the dimensions of an opening; or the method to create the opening; or the inspection of the penetrating item prior to firestop material installation. However, locating and defining the dimensions of an opening and the method to create the opening are critical to a firestop system''s installation.

1.8 This guide does not address all the test methods needed to address proper performance of all firestop systems or firestop materials.

1.9 This guide does not address all the test methods needed to address proper performance of firestop systems in all installations. For a specific application of a firestop system one or more of the following are consulted when available:

1.10 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.

1.11 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.
