低可燃性床垫和床垫套件放热率测量用标准试验法

[中文适用范围]： 本国际标准提供了一种全尺寸测试方法，用于测定床垫或床垫和床基的放热速率和总放热量。测试样本通过暴露在一对模拟燃烧床上用品的燃气燃烧器下点燃。测量能力设计用于低可燃性的床垫组，即放热速率峰值低于300千瓦。本国际标准适用于床垫和床垫与床基组。本国际标准不适用于床垫垫、枕头、毯子或其他用于床垫顶部的物品。本国际标准是一个性能标准，不规定任何特定组件、阻燃化学品或材料的使用，也不规定任何可能导致床垫组性能改进或退化的设计特征。附录A描述了一项分析，表明通过限制床火灾的规模可以实现的生命损失潜在减少。 [外文原描述]： ISO 12949:2011 provides a full-scale test method for determining the heat release rate and total heat release from a mattress or a mattress and foundation. The test specimen is ignited by exposure to a pair of gas burners that simulate burning bedclothes. The measurement capability is designed for mattress sets of low flammability, i.e. having a peak rate of heat release below 300 kW. ISO 12949:2011 applies to mattresses and mattress and foundation sets. ISO 12949:2011 does not apply to mattress pads, pillows, blankets, or other items used on top of a mattress. ISO 12949:2011 is a performance standard and does not prescribe the use of any specific components, fire retardant chemicals, or materials, and does not prescribe any design features that might lead to improved or degraded performance of a mattress set.
