标准范围

ISO 17554:2005规定了一种小规模方法，用于评估在通风良好的条件下，使用外部点火器，在水平方向暴露在受控辐射加热水平下的基本平坦试样的质量损失率。质量损失率由试样质量的测量确定，并通过数值推导得出。点火时间（持续燃烧）也在本测试中测量。质量损失率可用于间接测量许多产品的热释放率。

ISO 17554:2005 specifies a small-scale method for assessing the mass loss rate of essentially flat specimens exposed in the horizontal orientation to controlled levels of radiant heating with an external igniter under well-ventilated conditions. The mass loss rate is determined by measurement of the specimen mass and is derived numerically. The time to ignition (sustained flaming) is also measured in this test. Mass loss rate can be used as an indirect measure of heat release rate for many products.
