标准范围

规定了两种测定粒度大于2mm的粒状耐火材料体积密度（颗粒密度）的方法。方法1（真空汞法）拟作为参考方法。方法2为滞留吸水法。这两种方法可能给出不同的结果。因此，任何关于舱底密度值的声明应附有所用方法的说明。测定样品体积、选择和制备样品、计算体积密度和提交试验报告时，应使用相同的方法。

Two methods for the determination of the bulk density of granular refractory materials (grain density) having a grain size larger than 2mm are specified. Method 1 (mercury method with vacuum) is intended as a referee method. Method 2 is the arrested water absorption method. The two methods may give different results. Any statement of the value of a bilk density shall therefore be accompanied by an indication of the method used. The same method shall be used for the determination of the volume of the sample, for selecting and preparing the sample, for calculating the bulk density and for presenting the test report.
