标准范围

ISO 12989-2:2004涵盖了铝生产行业中使用的成型碳电极的空气反应性和除尘的热重分析（TGA）。可以使用多种类型的仪器，具有不同的热条件、样本容量、结构材料和用于确定质量损失和后续反应速率的程序。该试验方法设定了标准反应时间和温度，并提供了一种数学方法来规范暴露表面上的气体速度，从而使在不同类型的仪器上获得的结果具有相关性。

ISO 12989-2:2004 covers the thermogravimetric analysis (TGA) of air reactivities and dusting of shaped carbon electrodes used in the aluminium-production industry. Many types of apparatus are available, with various thermal conditions, sample-size capability, materials of construction and procedures for determining the mass loss and subsequent rate of reaction. This test method sets standard reaction times and temperatures, and provides a mathematical method to normalize the gas velocity over the exposed surfaces, such that results obtained on different types of apparatus are correlatable.
