1.1 This practice describes the required smoldering ignition fire properties for seating, upholstery, and padding materials used for vehicles associated with amusement rides and devices. 1.2 This practice includes an annex with an example of an optional open flame test method for padding materials. 1.3 This practice also contains a non-mandatory appendix with optional guidance for the procedure to follow in the event that an optional fire hazard analysis is to be conducted for vehicles used on amusement rides and devices. 1.3.1 In the event that such a fire hazard analysis is to be conducted, it needs to include considerations related to heat release, smoldering, and flaming ignition, flame spread and smoke release. 1.3.2 The appendix contains specific recommendations of standardized fire test methods that are suitable (but not required) for determining material properties related to heat release rates, smoldering, and flaming ignition, flammability, and smoke release for materials. 1.4 This practice is not a fire test method. 1.5 This practice does not require the conduction of a fire hazard analysis. 1.6 This practice does not address the use of active fire protection measures, such as fire sprinklers, or smoke, fire, or heat detectors. 1.7 This practice does not address the probability of any fire scenario associated with amusement rides or devices resulting in a hazardous event. Thus, this practice does not address the potential risk associated with any fire scenario. Practice F2291-21 includes general requirement to assess and mitigate hazards for all rides and devices. 1.8 This practice shall not apply to: 1.8.1 Materials specified for amusement rides or devices other than those associated specifically with the ride vehicle assembly. 1.8.2 Materials used for the construction of facilities. 1.8.3 Fluids and lubricants. 1.8.4 Vehicles used on water slides or other aquatic devices. 1.9 The values stated in SI units, see IEEE/ASTM SI-10-16 , are to be regarded as standard. The values given in parentheses, if any, after SI units are provided for information only and are not considered standard. 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. ====== Significance And Use ====== 4.1 This practice requires that seating, upholstery, and padding materials used for vehicles associated with amusement rides and devices exhibit adequate smoldering ignition properties. 4.1.1 Noncombustible materials are permitted to be used as seating, upholstery, and padding materials, and do not require testing for smoldering ignition. 4.2 The structural components or framing associated with a vehicle or ride are not considered seating, upholstery, or padding materials. 4.3 Annex A1 provides an optional open flame test suitable for seat padding materials. 4.4 Appendix X1 provides non-mandatory guidance for conducting an analysis of fire scenarios associated with the operation of vehicles associated with amusement rides and devices. The conduction of a fire hazard analysis is not a requirement of this practice. The purpose of Appendix X1 is to provide manufacturers, owners, and operators with criteria and references for fire properties of materials used in vehicles either following construction or major modifications of an amusement ride or device. 4.5 This practice does not address the probability of occurrence of a hazardous event in any fire scenario associated with amusement rides or devices. Thus, this practice does not address the potential risk associated with any fire scenario. Practice F2291 -21 includes general requirement to assess and mitigate hazards for all rides and devices. 4.6 The requirements in this practice are not intended to supersede any additional or alternate requirements provided by the authority having jurisdiction.
