The results do mean something - quantitatively! Consider, for example, that we decide to set a limit of 0.1% of unacceptable particles in a defined batch. 2 unacceptable particles would then be the most that could be tolerated in a batch of 2000 (2 being 0.1% of 2000). We now have to ensure that the sample size examined contains at least 2000 particles. As shown previously there will be at least 2000 particles in the total number of fields specified for each normal particle size.
