Standard Test Method for Fire Testing of Stacked Chairs

Standard Test Method for Fire Testing of Stacked Chairs

SCOPE
1.1 This is a fire-test-response standard.
1.2 This test method provides a means of determining the burning behavior of stacking chairs used in public occupancies by measuring specific fire-test responses when a stack of chairs is subjected to a specified flaming ignition source under well ventilated conditions.
1.3 This test method is limited to stacked chairs.
1.4 Test data are obtained describing the burning behavior following application of a specific ignition source, from ignition until all burning has ceased, a period of 1 h has elapsed, or flashover under test conditions appears inevitable.
1.5 This test method does not provide information on the fire performance of stacked chairs under fire conditions other than those conditions specified in this test method. In particular, this test method does not apply to smoldering ignition by cigarettes. See 5.11 for further information.
1.6 The rate of heat release of the burning test specimen is measured by an oxygen consumption method. See 5.11.4 for further information.
1.7 Other measurements are the production of light-obscuring smoke and the concentrations of certain toxic gas species in the combustion gases. See 5.11.5 for further information.
1.8 The burning behavior is documented visually by photographic or video recordings.
1.9 This standard is used to measure and describe 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.
1.10 Fire testing of products and materials is inherently hazardous, and adequate safeguards for personnel and property shall be employed in conducting these tests. This test method may involve hazardous materials, operations, and equipment.
1.11 Use the SI system of units in referee decisions; see Practice E 380. The units given in parentheses are for information only.
1.12 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.

Standard Test Method for Fire Testing of Mattresses

SIGNIFICANCE AND USE
5.1 This test method provides a means of measuring a variety of fire-test-response characteristics resulting from burning a test specimen, mattress or mattress with foundation. After ignition using a propane gas burner, the test specimen is permitted to burn freely under well-ventilated conditions. The most important fire-test-response characteristic measured in this test method is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. Annex A3 discusses the assumptions and limitations.  
5.3 This test method also provides measures of other fire-test-response characteristics, including smoke obscuration (as the rate of smoke release, total smoke released, or optical density of smoke), combustion gas release (as concentrations of combustion gases), and mass loss, which are important to making decisions on fire safety.  
5.4 In the majority of fires, the most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: (1) as part of fire hazard assessment calculations and (2) to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are also indicators of the toxicity of the atmosphere, but are less crucial for determining combustion completeness and are optional measures; however, fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (flaming source) is common in both accidental and intentional fires in public occupancies. The test method is thus applicable to mattresses in public occupancies. Such facilities include, but are not limited to, health-care facilities, old age convalescent and board and care homes, and college dormitories and residence halls.

Standard Test Method for Fire Testing of Upholstered Furniture

SIGNIFICANCE AND USE
5.1 This test method provides a means to measure a variety of fire-test-response characteristics resulting from burning a specimen of upholstered furniture. The upholstered furniture specimen is allowed to burn freely under well-ventilated conditions after ignition using a propane gas burner. The most important fire-test-response characteristic measured is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. The assumptions and limitations of oxygen depletion calorimetry are discussed in Annex A4, and in particular in A4.1.2.  
5.3 Other fire-test-response characteristics are measured, namely smoke obscuration and combustion gas release, as they are also important in making decisions on fire safety.  
5.4 The most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are less crucial for determining combustion completeness and are optional measures, but fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (a flaming source) is common in both accidental and intentional fires in public occupancies. This test method is thus applicable to upholstered furniture in public occupancies. Such facilities include, but are not limited to, jails, prisons, nursing care homes, health care facilities, public auditoriums, hotels, and motels.  
5.6 It has been shown that if the gas burner is used at a flow rate of 13 L/min for 80 s (equivalent to 19.3 kW), as is the case in California Technical Bulletin (CA TB) 133, it approximates the ignition propensity of five cru...
SCOPE

1.2 The purpose of this test method is to determine the burning behavior of upholstered furniture used in public occupancies by measuring specific fire-test responses when the specimen of furniture is subjected to a specified flaming ignition source under well-ventilated conditions.  
1.3 Data are obtained describing the burning behavior from a specific ignition source until all burning has ceased, a period of 1 h has elapsed, or flashover appears inevitable.  
1.4 This test method does not provide information on the fire performance of upholstered furniture in fire conditions other than those conditions specified. In particular, this test method does not apply to smoldering ignition by cigarettes. See X1.6 for further information.  
1.5 The rate of heat release of the burning specimen is measured by an oxygen consumption method. See X1.6.4 for further information.  
1.6 The production of light obscuring smoke is measured and the concentrations of certain toxic gas species in the combustion gases are determined. See X1.6.5 for further information.

ASTM E1474-22(Test Method)
Standard Test Method for Determining the Heat Release Rate of Upholstered Furniture and Mattress Components or Composites Using a Bench Scale Oxygen Consumption Calorimeter

SIGNIFICANCE AND USE
5.1 This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus.  
5.2 Quantitative heat release measurements provide information that can be used for upholstery and mattress product designs and product development.  
5.3 Heat release measurements provide useful information for product development by yielding 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 does not spread flame over its surface under the fire exposure conditions of interest.  
5.4 Test Limitations—The test data are invalid if either of the following conditions occur: (1) explosive spalling; or (2) the specimen swells sufficiently prior to ignition to touch the spark plug, or the specimen swells up to the plane of the heater base during combustion.
SCOPE
1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter.  
1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heat fluxes. The specimen is oriented horizontally, and a spark ignition source is used.  
1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354.  
1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 This standard is used to measure and describe 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 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. For specific precautionary statements, see Section 6.  
1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.9 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 Guide for Selection of Fire Test Methods for the Assessment of Upholstered Furnishings in Detention and Correctional Facilities

SIGNIFICANCE AND USE
5.1 The information presented provides the user with guidance on identification of test methods, and related documents, which are potentially useful to determine fire-test-response characteristics of upholstery products, and the materials of which they are made, present inside detention cells, in detention and correctional facilities. Some information is given about every standard included, so as to allow a judgment as to the potential usefulness of the original method.  
5.2 The detention environment has some unique features which potentially require the use of modifications of standard test methods or the application of particular techniques. Some guidance to that effect is also presented.
SCOPE
1.1 This is a fire-test-response guide.  
1.2 This guide is intended to provide guidance for the selection of test methods that are applicable to determining fire-test-response characteristics of upholstered furniture items contained within a detention cell.  
1.3 This guide is intended for use by those interested in assessing the fire properties of the upholstery products and their component materials or composites, within cells and other areas (such as isolation lounges) of detention and correctional occupancies.  
1.4 This guide includes standard test methods promulgated by ASTM, NFPA, Underwriters Laboratories, trade associations and government agencies and other proposed test methods. It does not include industrial materials specification tests. The guide indicates some means by which modifications of standard test methods lead to potential achievement of certain testing goals.  
1.5 The values stated in SI units are to regarded as standard; see IEEE/ASTM SI 10 for further details. The units given in parentheses are for information only. Some individual standards referenced use inch-pound units for referee decisions.  
1.6 This guide contains four types of test methods, namely: (1) generic small-scale methods, (2) specific applications of small-scale test methods to particular products or composites of products, associated with upholstery items, (3) real-scale test methods where actual upholstery products are exposed to heat or flame, and (4) guides explaining the concepts involved with room-scale testing.  
1.7 The main fire-test-response characteristics investigated in this guide are: ignitability, ease of extinction, flame spread, heat release, smoke obscuration and toxic potency of smoke.  
1.8 This guide 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.  
1.9 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.10 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.  
1.11 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 F1550-22(Test Method)
Standard Test Method for Determination of Fire-Test-Response Characteristics of Components or Composites of Mattresses or Furniture for Use in Correctional Facilities after Exposure to Vandalism, by Employing a Bench Scale Oxygen Consumption Calorimeter

SIGNIFICANCE AND USE
5.1 This test method provides a means to determine various fire-test-response characteristics, including the time to sustained flaming and the heat release rate, of composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus, after they have been vandalized in a prescribed manner, to expose the filling material.  
5.2 It is clearly impossible to predict the manner in which a mattress or furniture will be vandalized. The objective of this test method is to develop data indicating the effect of violating the integrity of the fabric (or the fabric plus interliner composite) protection and exposing the padding to the source of heat (see Appendix X3).  
5.3 Quantitative heat release measurements provide information which is useful for product design and product development, for mattresses or furniture destined for correctional occupancies.  
5.4 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 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.  
5.5 The use of test specimens simulating vandalism allows the investigation of the variation in response between the system as designed by the manufacturer and the way the system is occasionally present in actual use, with the filling material exposed to the incident energy.  
5.6 This test method allows alternative strategies to be employed for producing a product (mattress or upholstered furniture) with the required fire-test-response characteristics for the scenario under consideration.  
5.7 Limitations:  
5.7.1 The test data are invalid if any of the events in 5.7.1.1 or 5.7.1.2 occur.
5.7.1.1 Explosive spalling.
5.7.1.2 The specimen swells sufficiently prior to ignition to touch the spark plug or swells up ...
SCOPE
1.1 This fire-test-response test method is designed for use to determine various fire-test-response characteristics, including ignitability and heat release rate, from composites of mattresses or furniture, or correctional facilities, which have been vandalized in a prescribed manner to expose the filling material, by using a bench scale oxygen consumption calorimeter.  
1.2 This test method provides for measurements of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant radiant initial test heat flux of 35 kW/m2. See 5.7 for limitations.  
1.3 The apparatus used in this test method is also capable of determining heat release data at different initial test heat fluxes.  
1.4 The specimen is oriented horizontally and a spark ignition source is used.  
1.5 All fire-test-response characteristics are determined using the apparatus and the procedures described in Test Method E1354.  
1.6 The tests are done on bench-scale specimens combining the mattress or furniture outer layer components. Frame elements are not included.  
1.7 The vandalism is simulated by causing a prescribed cut on the outer layer of the composite, deep enough to expose the filling material to the incident radiation.  
1.8 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.  
1.9 This standard is used to measure and describe 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.  
1.10 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 ...

Standard Test Method for Determining the Heat Release Rate of Upholstered Furniture and Mattress Components or Composites Using a Bench Scale Oxygen Consumption Calorimeter

SIGNIFICANCE AND USE
5.1 This test method is used to determine the time to sustained flaming and heat release of materials and composites exposed to a prescribed initial test heat flux in the cone calorimeter apparatus.  
5.2 Quantitative heat release measurements provide information that can be used for upholstery and mattress product designs and product development.  
5.3 Heat release measurements provide useful information for product development by yielding 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 does not spread flame over its surface under the fire exposure conditions of interest.  
5.4 Test Limitations—The test data are invalid if either of the following conditions occur: (1) explosive spalling; or (2) the specimen swells sufficiently prior to ignition to touch the spark plug, or the specimen swells up to the plane of the heater base during combustion.
SCOPE
1.1 This fire-test-response test method can be used to determine the ignitability and heat release from the composites of contract, institutional, or high-risk occupancy upholstered furniture or mattresses using a bench scale oxygen consumption calorimeter.  
1.2 This test method provides for measurement of the time to sustained flaming, heat release rate, peak and total heat release, and effective heat of combustion at a constant initial test heat flux of 35 kW/m2. This test method is also suitable to obtain heat release data at different heat fluxes. The specimen is oriented horizontally, and a spark ignition source is used.  
1.3 The times to sustained flaming, heat release, and effective heat of combustion are determined using the apparatus and procedures described in Test Method E1354.  
1.4 The tests are performed on bench-scale specimens combining the furniture or mattress outer layer components. Frame elements are not included.  
1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.  
1.6 This standard is used to measure and describe 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 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. For specific precautionary statements, see Section 6.  
1.8 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.  
1.9 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 Fire Testing of Upholstered Furniture

SIGNIFICANCE AND USE
5.1 This test method provides a means to measure a variety of fire-test-response characteristics resulting from burning a specimen of upholstered furniture. The upholstered furniture specimen is allowed to burn freely under well-ventilated conditions after ignition using a propane gas burner. The most important fire-test-response characteristic measured is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. The assumptions and limitations of oxygen depletion calorimetry are discussed in Annex A4, and in particular in A4.1.2.  
5.3 Other fire-test-response characteristics are measured, namely smoke obscuration and combustion gas release, as they are also important in making decisions on fire safety.  
5.4 The most important gaseous components of smoke are the carbon oxides, present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat release measurements. Other toxic combustion gases, which are specific to certain materials, are less crucial for determining combustion completeness and are optional measures, but fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (a flaming source) is common in both accidental and intentional fires in public occupancies. This test method is thus applicable to upholstered furniture in public occupancies. Such facilities include, but are not limited to, jails, prisons, nursing care homes, health care facilities, public auditoriums, hotels, and motels.  
5.6 It has been shown that if the gas burner is used at a flow rate of 13 L/min for 80 s (equivalent to 19.3 kW), as is the case in California Technical Bulletin (CA TB) 133, it approximates the ignition propensity of five cru...
SCOPE
1.1 This is a fire-test-response standard.  
1.2 The purpose of this test method is to determine the burning behavior of upholstered furniture used in public occupancies by measuring specific fire-test responses when the specimen of furniture is subjected to a specified flaming ignition source under well-ventilated conditions.  
1.3 Data are obtained describing the burning behavior from a specific ignition source until all burning has ceased, a period of 1 h has elapsed, or flashover appears inevitable.  
1.4 This test method does not provide information on the fire performance of upholstered furniture in fire conditions other than those conditions specified. In particular, this test method does not apply to smoldering ignition by cigarettes. See X1.6 for further information.  
1.5 The rate of heat release of the burning specimen is measured by an oxygen consumption method. See X1.6.4 for further information.  
1.6 The production of light obscuring smoke is measured and the concentrations of certain toxic gas species in the combustion gases are determined. See X1.6.5 for further information.  
1.7 The burning behavior is visually documented by photographic or video recordings, whenever possible.  
1.8 The system of units to be used in referee decisions is the SI system of units, see IEEE/ASTM SI-10 only. The units given in parentheses are for information only.  
1.9 This standard is used to measure and describe 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.  
1.10 Fire testing is inherently hazardous. Adequate safeguards for personnel and property shall be employed in conducting these tests.

Standard Test Method for Fire Testing of Stacked Chairs

SIGNIFICANCE AND USE
5.1 This test method provides a means of measuring a variety of fire-test-response characteristics resulting from burning a stack of five stacking chairs. After ignition using a propane gas burner, the test specimen is permitted to burn freely under well-ventilated conditions. The most important fire-test-response characteristic measured in this test method is the rate of heat release, which quantifies the intensity of the fire generated.  
5.2 The rate of heat release is measured by the principle of oxygen consumption. Annex A3 discusses the assumptions and limitations.  
5.3 This test method also provides measures of other fire-test-response characteristics, including smoke obscuration (as the rate of smoke release, total smoke released or optical density of smoke), combustion gas release (as concentrations of combustion gases), and mass loss, that are important to making decisions on fire safety.  
5.4 In the majority of fires, the most important gaseous components of smoke are the carbon oxides present in all fires. They are indicators of the toxicity of the atmosphere and of the completeness of combustion. Measurement of concentrations of carbon oxides are useful for two purposes: as part of fire hazard assessment calculations and to improve the accuracy of heat-release measurements. Other toxic combustion gases, which are specific to certain materials, are also indicators of the toxicity of the atmospheres, but are less crucial for determining combustion completeness and are optional measures; however fire hazard assessment often requires their measurement.  
5.5 The type of ignition chosen (flaming source) is common in both accidental and intentional fires in public occupancies. This test method is thus applicable to stacked chairs in public occupancies. Such facilities include, but are not limited to, health-care facilities, old-age convalescent and board and care homes, college dormitories and residence halls, and hotels and motels.
