标准编号：ISO 8840:2021

中文名称：耐火材料 粒状材料体积密度的测定（颗粒密度）

英文名称：Refractory materials — Determination of bulk density of granular materials (grain density)

发布日期：2021-09

标准范围

This document specifies three methods for the determination of the bulk density of granular refractory materials (grain density) having a grain size larger than 2 mm:
— Method 1: mercury method with vacuum;
— Method 2: arrested water absorption method;
— Method 3: vacuum method with spin dryer option according to ISO 5017.
Method 1 is intended as the reference method.
