标准范围

该程序包括在显微镜下检查少量样品，如果存在不同颜色或直径的颗粒，则分别选择几个颗粒，将选定的颗粒放置在两个玻璃显微镜载玻片之间，并在施加压力的同时，以往复运动的方式缓慢移动一个载玻片，持续10秒，检查玻璃表面是否有划痕。该方法的目的是评估样品在莫氏硬度计上的最小硬度是否为6。附录A给出了非金属喷砂清理磨料ISO 11126和ISO 11127的国际标准系列信息。

The procedure includes examining a small quantity of the sample under the microscope and, if grains of different colours or diameter are present, selecting a few grains of each, placing the selected grains between two glass microscope slides and, whilst applying pressure, slowly moving one slide over the other with a reciprocating motion for 10 s, examining the glass surfaces for scratches. The object of the method is to assess whether the sample has a minimum hardness of 6 on Mohs' scale. Annex A gives information on the international standards series for non-metallic blast-cleaning abrasives ISO 11126 and ISO 11127.
