This document specifies a test method for the determination of the resistance of fire dampers to heat, and for the evaluation of their ability to prevent fire and smoke from spreading from one fire compartment to another through an air distribution system. This document describes the test requirements related to intumescent fire dampers. It is intended for intumescent fire dampers that are expected to be classified as EI dampers. Without the addition of a mechanical damper, they are unable to achieve the “S” classification, which includes a leakage limit imposed at ambient temperature. This document is not intended to be used for dampers used only in smoke control systems, for testing fire protection devices which only deal with air transfer applications, or for dampers used in suspended ceilings, as the installation of the damper and duct can have an adverse effect on the performance of the suspended ceiling, requiring other methods of evaluation. NOTE      "Air transfer" is a low-pressure application through a fire separation door (or wall, floor) without any connection to an air duct.

This document specifies a test and assessment method for determining the contribution of fire protection systems to the fire resistance of circular and rectangular solid steel bar. ISO 834-10 and ISO 834-11 cover other section shapes such as angles, channels and flats. This document is not intended to be used for twisted wire or for cold or hot rolled steel bar which is primarily used for the reinforcement of concrete. This document is applicable for the protection of solid bar up to a maximum diameter of 130 mm and in the case of rectangular bar the maximum side length shall be limited to 130 mm with a maximum aspect ratio of 2:1 against the shorter length side. Beyond these limits, the solid steel bars are covered in ISO 834-10 and ISO 834-11. This document is intended to be used with any applied fire protection system, including multi-layered systems, that have demonstrated their integrity/stickability when tested on floor beams and hollow sections under load, and assessed in accordance with ISO 834-11. This document does not incorporate results from a loaded test on a tension member. Guidance for conducting a fire test on a steel bar under a tensile load is provided in Annex C. This document contains the fire test methodology to provide data on the thermal characteristics of the fire protection system when exposed to the standard temperature/time curve specified in ISO 834-1. It also contains an assessment method for the analysis of the test data. The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes over the range of thicknesses of the applied fire protection system tested. The assessment procedure is used to establish: — on the basis of temperature data derived from testing steel bars, any practical constraints on the use of the fire protection system under fire test conditions, (the physical performance); — on the basis of the temperature data derived from testing steel bars, the thermal properties of the fire protection system, (the thermal performance). The limits of applicability of the results of the assessment arising from the fire test are defined together with permitted direct application of the results to different steel types and sizes of steel bar over the range of thicknesses of the applied fire protection system tested. This document describes testing in both the vertical and horizontal orientations at the discretion of the sponsor.

This document specifies a test and assessment method for determining the contribution made by fire protection systems to the fire resistance of structural steel beams, I and H sections, in the horizontal plane containing openings in the web which may affect the structural performance of the beam. It is applicable to beams subjected to three or four sided fire exposure. For any cellular beam with a single web opening or where the web openings are considered to be of small diameter in relation to the web depth the applicability of this document is intended to be determined by a structural engineer This document adopts the principle of establishing ratios of temperatures between and around openings in the web of a beam with the temperatures of a solid portion of that beam. This is with the intention that these data can be utilised within a structural model to derive the value and location of the associated limiting temperature of the beam at the fire limit state. The limiting temperature is then used in conjunction with data for the fire protection material determined from ISO 834-10 and ISO 834-11 to determine the necessary thickness of fire protection material for beams with web openings. This document applies to fire protection materials that have already been tested and assessed in accordance with ISO 834-10 and ISO 834-11 and is not intended to be used in isolation. It covers fire protection systems that include both passive and reactive materials which follow the section profile as defined in this document. This document includes the use of a multi-temperature analysis (MTA) derived from ISO 834-11 as the basis for determining the thickness of fire protection for beams with web openings. This document contains an assessment method, which prescribes how the analysis of the test data should be made and gives guidance on the procedures that could be undertaken. The assessment procedure can be used to establish: a) The thermal response of the fire protection system on cellular beams, (the thermal performance) on the basis of the temperature data derived from testing unloaded steel sections. b) The temperature ratio between the web post and the web reference temperature, which will vary depending on the web post width. c) The temperature ratio between points around the web openings and the web reference area. d) A structural model that can be used to derive limiting temperatures for cellular beams.

This document explains a methodology to determine the applicability of the results of fire resistance tests to actual applications. It is applicable to those loadbearing and simple vertical and horizontal separating elements for which there is an ISO standard test procedure based upon the ISO 834 series for determining the fire resistance of a representative sample of the construction proposed for use in a specific building or just for general use. These elements are: —   loadbearing elements; —   non-loadbearing elements: —   partitions: —   stud construction partitions; —   composite panel/SIPS partitions; —   ceiling membranes (horizontal partitions): —   jointed ceilings; —   composite panel ceilings. Direct and extended applications of test results are the two possible ways to ensure that a modified element has an acceptable probability of obtaining the same fire rating as that of the original tested specimen. In both cases, these applications generally refer only to the fire rating that the building element can expect to reach if it, or a representative sample of it, were to be tested in a furnace according to the standard fire test conditions used in the reference test. One of the most common variations is in respect of the size of the element in use. Fire resistance testing furnaces have size restrictions and as a consequence, there is little confidence that the result obtained on an element of construction tested in accordance with the standard methods will behave in a similar manner when installed in the final building. This document does not provide guidance on the application and extension of results arising from testing carried out on door and window assemblies, linear gaps or service penetration seals, which is covered in ISO/TR 12470-2. For some, but not all of the critical parameters, a summary of the possible influences is incorporated in the given examples.

ISO/TR 12470-2:2017 explains a methodology to determine the applicability of the results of fire resistance tests to actual applications. ISO/TR 12470-2:2017 is applicable to those non-loadbearing elements for which there is an ISO standard test procedure based upon the ISO 834 series for determining the fire resistance of a representative sample of the construction proposed for use in a specific building or just for general use. These elements are: - fire resisting door assemblies (excluding lift landing doorsets): - timber; - steel; - fire resisting vertical glazing ? metal framed: NOTE The rheology of glass is such that gravity has a disproportional influence on fire glass when it is heated to high temperatures and as a consequence, it is not possible to provide generic guidance on the extended application of horizontal glazed elements. - timber framed; - linear gap sealing; - service penetration sealing. Fire resistance testing furnaces have fairly restricted size limitations and as a consequence, there is little confidence that the result obtained on an element of construction tested in accordance with the standard methods will behave in a similar manner when installed in the final building. Direct and extended applications of test results are the two possible ways to ensure that an element that is not identical to the tested construction will have an acceptable probability of obtaining the same fire rating as that of the original tested specimen. In both cases, these applications generally refer only to the fire rating that the building element can expect to reach if it, or a representative sample of it, were to be tested in a furnace according to the standard fire test conditions used in the reference test. The criteria and methodology used in evaluating ductwork and dampers is significantly different from those used to evaluate conventional separating elements and for this reason, these forms of construction are not included in the scope of this document. It is planned that a subsequent part of this document may include guidance on these elements.

The assessment detailed in ISO 834-11:2014 is designed to cover a range of thicknesses of the fire protection material, a range of steel sections characterized by their section factors, a range of design temperatures, and a range of valid fire resistance classification periods. ISO 834-11:2014 covers fire protection systems that include both passive (boards, mats, slabs, and spray materials) and reactive materials as defined in this document. The assessment procedure is used to establish: a) on the basis of the temperature data derived from testing loaded and unloaded specimens, a correction factor and practical constraints on the use of the fire protection system (the physical performance), and b) on the basis of the temperature data derived from testing unloaded short steel specimens, the thermal properties of the fire protection material (the thermal performance). The limits of applicability of the results of the assessment are defined together with permitted direct application of the results to different steel section sizes and strength grades (but not stainless steels) and to the fire protection system tested. The results of the tests obtained according to ISO 834‑10 and the assessment in this part of ISO 834 are directly applicable to steel sections of "I" and "H" cross-sectional shape and hollow sections. Results from analysis of I or H sections are directly applicable to angles, channels, and T-sections for the same section factor, whether used as individual elements or as part of a fabricated steel truss. The results of the assessment are applicable to fabricated sections. ISO 834-11:2014 does not apply to concrete-filled hollow sections, beams, or columns containing holes or openings of any type or solid bar.

ISO 834-10:2014 specifies a method for testing fire protection systems applied to structural steel members used in buildings as beams, columns, or tension members. It is intended for use in conjunction with the assessment protocol described in ISO 834‑11. It applies to steel sections (including hollow sections) and only considers sections without openings in the web. Results from analysis of I or H sections are directly applicable to angles, channels, and T-sections for the same section factor, whether used as individual members, e.g. bracing, or part of a fabricated structural system such as a steel truss construction. ISO 834-10:2014 does not apply to solid bar, rod, or concrete-filled hollow sections. ISO 834-10:2014 describes the fire test procedures that specify the tests which should be carried out to determine the ability of the fire protection system to remain sufficiently coherent and in position for a well-defined range of deformations, furnace, and steel temperatures, such that the efficacy of the fire protection system is not significantly impaired, and to provide data on the thermal characteristics of the fire protection system when exposed to the standard temperature/time curve specified in ISO 834‑1. In special circumstances, where specified in National Building Regulations, there can be a requirement to subject reactive fire protection materials to a smouldering curve. The test and the requirements for its use are described in ISO 834-10:2014 (Annex G). ISO 834-10:2014 is applicable to both passive and reactive fire protection systems as defined in the terms and definitions, which are installed or applied in such a way that they remain in place for the intended duration of fire exposure. The fire test methodology makes provision for the collection and presentation of data which is then used as direct input into ISO 834‑11 to determine the limits of direct application to steel sections of various shapes, sizes, and fire resistance periods.

ISO 834-12:2012 specifies the procedures to be followed for determining the fire resistance of non-load-bearing separating elements when exposed to heating on one face when the specimen size is such that a less than full scale fire resistance furnace is justified. This condition is particularly found in the testing of separating elements in transport applications since the end-use dimensions of the barrier products are often smaller than those specified in other parts of ISO 834. Specimen sizes requiring less than full size resistance furnaces are also found when testing elements to be fitted into a separating element, such as pipe penetration systems, ducts, dampers and cable transits. The test is not appropriate for the evaluation of curtain walls (non-load-bearing external walls suspended from the ends of floor slabs) or walls containing doors or glazing. Tests of walls containing doors are covered by ISO 3008; tests of walls containing glazing are covered by ISO 3009. The application of this test to other untested forms of construction is acceptable when the construction complies with the direct field of application as given in ISO 834-12:2012 or when it is subjected to a field of extended application analysis in accordance with ISO/TR 12470.

This part of ISO 10295 provides guidance in respect of a structured method of characterizing the penetrating seal under test utilizing a series of defined parameters, each one being determined by the use of a selected series of test configurations in conjunction with simulated services. The level of characterization being sought is dependent upon the classification requirement of the system, which in turn determines the complexity of the test program. It is also intended the test method addresses the influence the supporting construction has on the performance of the seal system. The methods described apply to the determination of data relating to single component penetration seals where the penetration service does not melt out within the appropriate period of exposure to a fully developed fire. The selection of the appropriate system depends upon many factors. Of particular importance is the size of the penetration, since penetration seal systems are frequently penetration size (or size range) specific. This is a guidance document, its purpose being to determine the critical parameters relating to the performance of the seal being evaluated. Such parameters can then be used as a basis for interpolation and/or extrapolation of the seal's performance. The procedures used have been developed utilizing small square penetrations, single component penetration seals, and cylindrical conductors; however it is possible to generate a similar series of tests using rectangular cross-section conductors if this is more appropriate to end use. This part of ISO 10295 provides a structured approach designed to establish — the mode of failure; — the parameters critical to the performance of the penetration seal under test. The mode of failure and critical parameters are ascertained using test configurations appropriate to the potential performance of the product, in conjunction with clearly defined standard penetrations. The results gained from the application of this technical report are designed to assist a suitably qualified person to develop a direct and extended field of application for the penetration seal under test using in particular, the principles and methodology given in ISO/TR 12470. Using the field(s) of application so generated, it should be possible to classify the penetration seal, thus facilitating its incorporation into specifications. The test configurations recommended in this part of ISO 10295 are not appropriate for evaluating multicomponent penetration seals. This part of ISO 10295 is not appropriate for characterizing all types of penetration seals, e.g. pipe closers/collars and some gland systems, for which evaluation using ISO 10295-1 is more appropriate. This part of ISO 10295 does not address the distance required between services that can generate their own heat. When a live service is being evaluated, it is necessary to give consideration to the distance required between penetrations.

ISO 10295-1:2007 specifies the heating condition, method of test and criteria for the evaluation of the ability of a penetration sealing system to maintain the integrity and insulation of a fire separating element at the position at which it has been penetrated, for example by a service. ISO 10295-1:2007 assesses the effect of such penetrations on the integrity and insulation performance of the element concerned, the integrity and insulation performance of the penetration sealing system, the insulation performance of the penetrating service or services, and where appropriate, the integrity failure of a service. ISO 10295-1:2007 does not provide information concerning the influence of the inclusion of such penetrations and sealing systems on the load-bearing capacity of the element. It is possible that a penetration seal is a component of, or contributes to the performance of, a system to which special requirements apply. In such cases additional tests, relevant to the system and its function, can be necessary. Examples are chimneys and fire-rated ducts in air distribution systems. ISO 10295-1:2007 is not intended to provide quantitative information on the rate of leakage of smoke and/or hot gases or on the transmission or generation of fumes. Such phenomena are to be noted in describing the general behaviour of specimens during test. ISO 10295-1:2007 does not provide information on the ability of the seal to withstand stresses that can be caused by the movement or displacement of the penetration services in practice.

ISO 10294-5:2005 describes the test requirements related to intumescent fire dampers. It identifies the minor modifications needed to adapt the test method described in ISO 10294-1 (which was intended for mechanical dampers) to suit intumescent fire dampers. Additional tests are included to give an assessment of the operational reliability of intumescent fire dampers. This test is intended for intumescent fire dampers that will be classified as EI dampers in accordance with ISO 10294-2. Without the addition of a mechanical damper, they are unable to achieve the "S" classification, which includes a leakage limit imposed at ambient temperatures.

ISO/TR 12471:2004 gives a review of the advances that have been made in measuring and understanding how structural materials respond to fire in terms of changes in their elevated temperature, and physical and mechanical characteristics, and to identify areas where further work is necessary to generate the data required. Analytical methods for heat transfer are combined with mechanical models to calculate structural behaviour from single elements up to complete frames under real fire and ISO Standard furnace heating conditions. ISO/TR 12471:2004 reviews advances in computational analysis and indicates how these can be used with probabilistic analysis to provide a risk-based approach to structural fire engineering design.

ISO/TR 15656:2003 provides guidance for evaluating the predictive capability of calculation models for structural fire behaviour. It is specific to models that are intended to predict the fire resistance or fire endurance of structural members or assemblies. Such models include models simulating the thermal behaviour and mechanical behaviour of fire-exposed load-bearing and/or separating structures and structural elements. In ISO/TR 15656:2003, the term model includes all calculation procedures that are based on physical models. These mechanistic-based or physical models encompass all the physical, mathematical and numerical assumptions and approximations that are employed to describe the behaviour of structural members and assemblies when subjected to a fire. In general, such physical models are implemented as a computer code on a digital computer. The application and extension of results from calculation methods are generally limited to performance resulting from standard tests. Aspects of ISO/TR 15656:2003 are applicable to calculation procedures not based on physical models. Mechanistic-based models can often be used to calculate the behaviour of structures in non-standard fire exposures. The process of model evaluation is critical in establishing both the acceptable uses and limitations of fire models. It is not possible to evaluate a model in total; instead, ISO/TR 15656:2003 is intended to provide methodologies for evaluating the predictive capabilities for specific uses. Documentation of suitability for certain applications or scenarios does not imply validation for other scenarios.

ISO 3009:2003 provides a test method for determining and assessing the fire resistance performance of both insulated and uninsulated glazed elements of building construction, when those elements are exposed to heating on one face. It is applicable to glazed separating elements such as screens, walls of glass blocks and other light-transmitting assemblies used in vertical, inclined or horizontal orientations, and to all separating elements containing glazing intended to be assessed in accordance with ISO 834-1, except for doors and shutter assemblies, which are intended to be tested in accordance with ISO 3008. It is directly applicable to planar elements, but also gives guidance on the testing of non-planar elements such as pyramids.

ISO 12472:2002 specifies a test method for determining the effective sealing capability of intumescent materials or systems in the context of sealing door-to-frame clearances in timber door assemblies. The method is suitable for evaluating the efficacy of exposed intumescent sealing systems used in conjunction with timber fire resisting doors of up to 1 h fire resistance. It is not suitable for comparing concealed intumescent seals. The results can be applied to proven, single-acting, single-leaf, latched, timber door assemblies of sizes up to that given in the field of direct application.

ISO 834-9:2002 specifies test procedures for determining the fire resistance of non-loadbearing ceiling elements, which possess fire resistance independent of any building element above them, when exposed to heating from below the ceiling. It is applicable to self-supporting ceilings and to ceilings suspended from, or fixed directly to, a supporting construction. It is not applicable to ceilings used as a horizontal fire barrier for the protection of a loadbearing element above, in which case performance is assessed as an integral part of the complete assembly using ISO 834-5.

ISO 834-8:2002 specifies the procedures to be followed for determining the fire resistance of non-loadbearing vertical separating elements when exposed to heating on one face. This test is neither appropriate for the evaluation of curtain walls (non-loadbearing external walls suspended from the ends of floor slabs) nor for walls containing doors or glazing. For tests of walls containing doors refer to ISO 3008. For tests of walls containing glazing refer to ISO 3009. The application of this test to other untested forms of construction is acceptable when the construction complies with the direct field of application as given in ISO 834-8:2002 or when it is subjected to a field of extended application analysis in accordance with ISO/TR 12470.
