UNE 118028:2018
This standard specifies a practical system for dividing tobacco and tobacco products batches (not necessarily homogeneous) both, within a single laboratory or between different laboratories, for subsequent chemical tobacco analysis. The main objective is the procurement of similar samples as far as possible for carrying out collaborative analysis. Note: This system does not intend that the obtained samples be representative of the sampled population, but that they are similar as much as possible, so that they are useful for comparing the results in collaborative analysis.
