Scope

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.
