标准范围

规定了实验室样品、用于测定某些几何特性的粗样品以及物理和物理化学试验（包括测定水分含量和干燥样品）的制备。其原理是对样品进行研磨和筛分，直到完全通过孔径为0.2mm的筛网。在约300°C下混合和干燥。取代ISO建议R 802-1968。

Specifies the preparation of laboratory samples, crude samples for the determination of certain geometric properties and physical and pysico-chemical tests including the determination of moisture content and dried samples. The principle consists in grinding and sieving of the sample until passing completely through a sieve of meshes having apertures of 0,2 mm. Mixing and drying at about 300 °C. Replaces ISO Recommendation R 802-1968.
