ASTM D6113-10 使用锥形量热计测定电缆或光缆用绝缘材料的火灾试验反应特性的标准试验方法

This test method is used to determine the heat release rate and a number of other fire-test-response characteristics as a result of exposing insulating materials contained in electrical or optical cables to a prescribed heating flux in the cone calorimeter apparatus. Quantitative heat release measurements provide information that is potentially useful for design of electrical or optical cables, and product development. Heat release measurements provide useful information for product development by giving a quantitative measure of specific changes in fire performance caused by component and composite modifications. Heat release data from this test method will not be predictive of product behavior if the product will not spread flame over its surface under the fire exposure conditions of interest. The fire-test-response characteristics determined by this test method are affected by the thickness of the material used as test specimen, whether as a plaque or as coating on a wire or cable. The diameter of the wire or cable used will also affect the test results. A radiant exposure is used as an energy source for this test method. This type of source has been used for comparison with heat release rate and flame spread studies of insulating materials constructed into cables when burning in a vertical cable tray configuration (Test Methods D5424 and D5537) (2-9). No definitive relationships have been established. The value of heat release rate corresponding to the critical limit between propagating cable fires and non-propagating fires is not known. This test method does not determine the net heat of combustion. It has not been demonstrated that this test method is capable of predicting the response of electrical or optical fiber cables in a full scale fire. In particular, this test method does not address the self-extinguishing characteristics of the cables in a full scale fire.1.1 This is a fire-test-response standard. 1.2 Several fire-test-response characteristics, including the time to sustained flaming, heat release rate, total heat released, effective heat of combustion, and specific extinction area; are measured or calculated by this test method at a constant radiant heating flux. For specific limitations see also 5.7 and Section 6. 1.3 The tests are conducted by burning the electrical insulating materials contained in electrical or optical fiber cables when the cable test specimens, excluding accessories, are subjected to radiant heat. 1.4 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 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 or regulatory limitations prior to use. For specific precautionary statements, see Section 7. 1.6 This standard measures and describes the response of materials, products, or assemblies to heat and flame under controlled conditions, but does not by itself incorporate all factors required for fire hazard or fire risk assessment of the materials, products or assemblies under actual fire conditions. 1.7 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

The lists of components and materials are useful in enhancing the user''s understanding of the technology and construction of fiber-optics cables and the development of performance standards for cables. This guide is intended for use by all parties involved with fiber optics: materials suppliers, cable manufacturers, and end-users.1.1 This guide is intended to provide a list of materials commonly used in components that provide insulation, jacketing and strength in fiber-optic cables. Where these materials are covered by ASTM standards, an appropriate reference is made. Due to changing technology, not all materials being used are necessarily listed here. 1.2 This guide does not include materials used in components for optical purposes (optical fiber and its coating) or external metallic armoring (such as for a barrier to rodents). 1.3 This guide offers two general lists of materials: 1.3.1 A subdivision of fiber-optic cable construction into components that are used for insulation, jacketing, or strength, with a generic material classification for specific applications in each component (see Section 5); and 1.3.2 An alphabetical list of the generic material classifications, showing ASTM standards where they exist (see Table 1).

Ionizing environments will affect the performance of optical fibers/cables being used to transmit spectroscopic information from a remote location. Determination of the type and magnitude of the spectral variations or interferences produced by the ionizing radiation in the fiber, or both, is necessary for evaluating the performance of an optical fiber sensor system. The results of the test can be utilized as a selection criteria for optical fibers used in optical fiber Raman spectroscopic sensor systems. Note 18212;The attenuation of optical fibers generally increases when they are exposed to ionizing radiation. This is due primarily to the trapping of radiolytic electrons and holes at defect sites in the optical materials, that is, the formation of color centers. The depopulation of these color centers by thermal or optical (photobleaching) processes, or both, causes recovery, usually resulting in a decrease in radiationinduced attenuation. Recovery of the attenuation after irradiation depends on many variables, including the temperature of the test sample, the composition of the sample, the spectrum and type of radiation employed, the total dose applied to the test sample, the light level used to measure the attenuation, and the operating spectrum. Under some continuous conditions, recovery is never complete.1.1 This guide covers the method for measuring the real time, in situ radiation-induced alterations to the Raman spectral signal transmitted by a multimode, step index, silica optical fiber. This guide specifically addresses steady-state ionizing radiation (that is, alpha, beta, gamma, protons, etc.) with appropriate changes in dosimetry, and shielding considerations, depending upon the irradiation source. 1.2 The test procedure given in this guide is not intended to test the other optical and non-optical components of an optical fiber-based Raman sensor system, but may be modified to test other components in a continuous irradiation environment. 1.3 The values in SI units are to be regarded as standard. 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.
