ASTM E814 PDF

More E The performance of a firestop system is dependent upon the specific assembly of materials tested including the number, type, and size of penetrations and the floors or walls in which it is installed. An F rating shall be based upon flame occurrence on the unexposed surface, while the T rating shall be based upon the temperature rise as well as flame occurrence on the unexposed side of the firestop system. These ratings, together with detailed performance data such as the location of through-openings and temperatures of penetrating items are intended to be one factor in assessing performance of firestop systems. Scope 1. Firestop systems are intended for use in openings in fire-resistive walls and floors that are evaluated in accordance with Test Methods E

Scope 1. Firestop systems are intended for use in openings in fire-resistive walls and floors that are evaluated in accordance with Test Methods E However, this test method shall not be construed as determining the performance of the firestop system during actual fire conditions when subjected to forces such as failure of cable support systems and falling debris.

The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. These notes and footnotes excluding those in tables and figures shall not be considered requirements of the standard.
