This classification system is intended to encourage uniformity in reporting properties; to provide a common language for communications between suppliers and consumers; to guide engineers and designers in the test methods commonly used for commercially available materials; and to be versatile enough to cover new materials and test methods as they are introduced. This system is based on the principle that nonmetallic gasket materials can be described in terms of specific physical and mechanical properties. This enables the user, or producer, to characterize a nonmetallic gasket based on properties that are important for the application.1.1 This classification system provides a means for specifying or describing pertinent properties of commercial nonmetallic gasket materials. Materials composed of asbestos, cork, cellulose, and other organic or inorganic materials in combination with various binders or impregnants are included. Materials normally classified as rubber compounds are not included, since they are covered in Classification D2000. Gasket coatings are not covered, since details thereof are intended to be given on engineering drawings or in separate specifications. Facing materials for laminate composite gasket materials (LCGM) are included in Classification System F104. Assembled LCGMs are covered in Classification F868. 1.2 Since all of the properties that contribute to gasket performance are not included, use of the classification system as a basis for selecting materials is limited. 1.3 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.

The methods and procedures set forth in this guide relate to the extension of the fire test results to firestop systems that have not been tested. Users of this guide must have knowledge and understanding of the provisions of Test Method E119 and Test Method E814 including those pertaining to conditions of acceptance. In order to apply some of the principles described in this guide, reference to the original fire test report will be necessary. In Test Method E814, the specimens are subjected to specific laboratory fire test exposure conditions. Differences between the tested assembly and the as-built assembly impact the fire-test-response characteristics. Substitution of different test conditions also impacts the fire-test-response characteristics. The extension of data is valid only for the fire test exposure described in Test Method E814. This guide shall not be used to extrapolate the fire resistance rating to a higher value. Limitations: The extension of fire resistance data is to be used only for changes to the tested specimen that fall within normal and reasonable limits of accepted construction practices. Conclusions derived from using this guide are valid only if the identified change is the only change in the construction or properties of the components. Evaluation of changes to the fire-resistive assembly in which the firestop is installed is governed by the Extension of Data principles in Guide E2032. The statements in this guide are based on a single change to a system. Note 28212;It is possible that multiple changes have a different cumulative effect than that of individual changes evaluated separately. The principles contained herein may provide useful information for the application of sound engineering principles to evaluate the effect of multiple differences between tested and installed firestops. Extensions of data using this document shall be done by individuals possessing the following minimum qualifications and attributes: an understanding of the Test Method E814 test procedure, an understanding of the fire behavior of firestop materials, knowledge of the elements of the construction to be protected, and an understanding of the probable behavior of the underlying construction and the recommended firestop system protecting it, were they to be subjected to testing in accordance with Test Method E814. The person performing evaluations based on tested or listed firestops shall be one of the following: the firestop manufacturer''s knowledgeable and qualified technical personnel, a registered professional engineer, or Fire Protection Engineer, knowledgeable in firestopping systems, an independent testing agency or a listing agency, or technical personnel with experience in firestopping.1.1 This guide covers the extension of results obtained from fire tests performed in accordance with Test Method E814 to applications that have not been tested.

5.1 Residential duct systems are often field designed and assembled. There are many joints, often of dissimilar materials that require both mechanical connection and air sealing. Without this sealing, duct systems would be extremely leaky and hence inefficient. While some duct sealants are rated on their properties at the time of manufacture or during storage, none of these ratings adequately addresses the in-service lifetime. This test method has been developed to address this durability issue. 5.2 This standard applies to products which list duct sealing as one of their uses. This includes duct tape (cloth, metal foil, or plastic backed), mastics, and sprayed/aerosol sealants. It does not apply to caulks or plaster patches that are not intended to be permanent duct sealing methods. 5.3 The standard duct leak site is a collar to plenum connection for round duct that is 10 to 20 cm [4 to 8 in.] in diameter. This perpendicular connection was chosen because almost all residential duct systems have this type of connection and in field observations of duct systems, it is often this type of connection that has sealant failure. 1.1 This test method describes an accelerated aging test for evaluating the durability of duct sealants by exposure to temperatures and static pressures characteristic of residential duct systems. 1.2 This test method is intended to produce a relative measure of the durability of duct sealants. This standard does not measure durability under specific conditions of weather and building operation that might be experienced by an individual building and duct system. Instead it evaluates the sealant method under fixed conditions that do not include the manifold effects of installation practice. 1.3 This test method only addresses sealants not mechanical strength of the connections. 1.4 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. For specific hazard statements see Section 7.

The hot compression properties of a gasket material, including creep resistance and compression set, are a major factor with regard to the selection of a given material for use in a particular sealing application. The significance of the test method is based, in part; on the assumption that if a material exhibits too much creep at elevated temperature that it will no longer function as effectively as a seal. This assumption can only be used as a guide; however, since exact yield or failure points are difficult to define for gasket materials (which are usually viscoelastic in nature). Two or more materials can be compared to determine differences in their hot compression properties. A sample of material can be compared to an established standard or previously determined characteristics on original lots of the same material, for quality assurance purposes. Samples are to be tested with a raised profile insert or calibration ring described in 6.3 and Fig. 1 so that the area (2042 mm2 (3.17 in.2)) remains constant during the test. FIG. 1 Test Assembly for Determining Hot Compression1.1 This test method covers a means of measuring the hot compression properties of a gasket material by measuring its creep under a constant load at both room temperature and while increasing the temperature. Short term creep properties including both cold and hot creep, total creep and compression set of a gasket material can be determined. 1.2 The values stated in SI units are to be regarded as standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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.
