采样是使用采样窃贼进行的。拆分是指使用拆分器（通常是琼斯取样器）将样品分成两等份，并在每一份样品上重复该程序，直到样品比试验所需量大25%。该方法可用于对均匀生产的磨粒进行对比试验。

Sampling is made using a sampling thief. Splitting means dividing into two equal portions using a splitter (commonly a Jones sampler) and repeating this procedure at each of the portions obtained until the sample is 25 % larger than the amount required for testing. The method may be used in the comparative testing of uniformly produced abrasive grains.
