标准摘要
[中文适用范围]： 建立了测量耐火制品和原材料真密度的方法。 它定义为一定量干燥材料的质量与其真实体积的比值，并通过以下表达式计算： 是恒温控制浴温度下所用液体的密度，m1、m2、m3 是质量按照第7条确定。 [外文原描述]： Establishes a method for measuring the true density of refractory products and raw materials. It is defined as the ratio of the mass of a quantity of dried material to its true volume and is calculated from the expression is the density of the liquid used at the temperature of the thermostatically controlled bath, and m1, m2, m3 are the masses determined in accordance with clause 7.
