Standard Guide for Extension of Data from Penetration Firestop System Tests Conducted in Accordance with ASTM E814

SIGNIFICANCE AND USE
4.1 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.  
4.2 Users of this guide must have knowledge and understanding of the provisions of Test Methods E119 and Test Method E814 including those pertaining to conditions of acceptance.  
4.3 In order to apply some of the principles described in this guide, reference to the original fire test report will be necessary.  
4.4 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.  
4.5 The extension of data is valid only for the fire test exposure described in Test Method E814.  
4.6 This guide shall not be used to extrapolate the fire resistance rating to a higher value.  
4.7 Limitations:  
4.7.1 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.  
4.7.2 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.  
4.7.3 Evaluation of changes to the fire-resistive assembly in which the firestop is installed is governed by the Extension of Data principles in Practice E2032.  
4.8 The statements in this guide are based on a single change to a system.
Note 2: 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.  
4.9 Extensions of data using this document shall be done by individ...
SCOPE
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. Test Method E814 evaluates the duration for which test specimens will contain a fire, retain their integrity, or both during a predetermined fire test exposure. Firestops are intended for use in fire-resistive walls and floors that are evaluated in conformance with Test Methods E119.
Note 1: Data obtained from firestops tested in accordance with Test Methods E119 with positive pressure can also be used.  
1.2 This guide is based on principles involving the extension of test data using simple considerations. The acceptance of these principles and their application is based substantially on an analogous worst-case proposition.  
1.3 These principles are only applicable to temperature conditions represented by the standard time-temperature curve described in Test Method E814, for systems falling within the scope of Test Method E814. This test method is a fire-test-response standard.  
1.4 The types of building constructions which are part of this guide are as follows: floors, walls, partitions, floor/ceiling and roof/ceiling assemblies.  
1.5 This guide applies to:  
1.5.1 a single penetrating item, or  
1.5.2 multiple penetrating items.

ASTM F2378-05(2023)(Test Method)
Standard Test Method for Sealability of Sheet, Composite, and Solid Form-in-Place Gasket Materials

SIGNIFICANCE AND USE
5.1 This test method is designed to compare sealing characteristics of gasket materials under controlled conditions by providing a precise measure of leakage rate at different press loads up to 32 MPa (4640 psi).  
5.2 This test method is suitable for measuring leakage rates from 0.1 mL/min to as high as 5 L/min for gases.  
5.3 This test method evaluates leak rates after time periods (typically 30 min) that result in a steady state leakage rate condition. Holding gasket materials under load and internal fluid pressure until steady state is achieved is required to obtain reproducible results.  
5.4 If the fluid being used in the test causes changes, such as swelling, in the gasket material, it may affect results and diminish repeatability.
SCOPE
1.1 This test method covers a means of evaluating the sealing properties of sheet, composite, and solid form-in-place gasket materials (see Classification F104 or F868) at room temperature, and may be used for fluid (gas or liquid) leak rate measurements. It utilizes relatively short hold times and is not intended to predict long-term performance in application.  
1.2 This test method is suitable for evaluating the sealing characteristics of a gasket material under different press loads by measuring the leakage rate. This test method may be used as an acceptance test when the producer and user have agreed to specific test conditions for the following parameters: (1) test medium, (2) internal pressure of the medium, (3) press load on the gasket specimen, and (4) the surface finish of the platens.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Standard Test Method for Creep Relaxation of Laminated Composite Gasket Materials

SIGNIFICANCE AND USE
4.1 This test method is designed to compare related materials under controlled conditions and their ability to maintain a given compressive stress as a function of time. A portion of the torque loss on the bolted flange is a result of creep relaxation. Torque loss can also be caused by elongation of the bolts, distortion of the flanges, and vibration; therefore, the results obtained should be correlated with field results. This test method may be used as a routine test when agreed upon between the user and the producer.
SCOPE
1.1 This test method provides a means of measuring the amount of creep relaxation of a laminated composite gasket material at a predetermined time after a compressive stress has been applied.  
1.2 Creep relaxation is measured by means of a calibrated bolt with dial indicator.  
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM F145-72(2023)(Practice)
Standard Practice for Evaluating Flat-Faced Gasketed Joint Assemblies

SIGNIFICANCE AND USE
4.1 Gasket compressions produced by bolt loads in a flanged joint are important in the application engineering of a joint assembly. They are related to the ability of a gasket to seal, to maintain tightness on assembly bolts, and to a variety of other gasket properties that determine the service behavior of a joint assembly. Thus, being able to determine the degree of compression in a gasket under the bolt loading will permit one to make qualitative predictions of the behavior of a joint assembly when it comes in contact with the application or service environment. With the plug test, bending of a flange facing between bolt centers can be measured; however, in a few highly distortable flanges the maximum bending between bolt centers may not be detected.  
4.2 The variation in gasket compressions at selected points in a flat-face joint assembly reveals the degree of flange distortion or the ability of the flange to distribute satisfactorily the compressive forces from bolt loads throughout the gasket.
SCOPE
1.1 This practice permits measurement of gasket compression resulting from bolt loading on a flat-face joint assembly at ambient conditions.  
1.2 The values stated in SI units are to be regarded as the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM F1087-02(2023)(Test Method)
Standard Test Method for Linear Dimensional Stability of a Gasket Material to Moisture

SIGNIFICANCE AND USE
3.1 Gasket materials undergo several processing steps from point of manufacture to installation in a flange. Many applications require close control of dimensional change. An accurate test method for determining the relative stability of various materials is needed for design and quality assurance purposes. This test method is useful towards that end. It simulates the extreme storage conditions that a material may undergo prior to installation. Samples are allowed unrestricted expansion or contraction, and so this test method should not be used to predict behavior clamped in a flange or other applications, or during specific processing steps.  
3.2 This test method measures linear change, and may need to be modified if the test specimen is not flat, homogeneous, or free of voids.
SCOPE
1.1 This test method covers a procedure to determine the stability of a gasket material to linear dimensional change due to hygroscopic expansion and contraction. It subjects a sample to extremes, that is, oven drying and complete immersion in water, that have shown good correlation to low and high relative humidities.2  
1.2 The values stated in SI units are to be regarded as the 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
