General:

This standard describes acceptable methods for obtaining representative samples of wood preservatives under most phases of shipment, storage and use. Since samples may have to be obtained under varying conditions, it may be necessary or advisable to depart from the sampling routines described in this Standard. Good judgment, skill and experience are required to obtain representative samples in unique circumstances. It should always be remembered, however, that it is essential to obtain a sample or a composite of several samples in such a manner and from such locations that the sample or composite is truly representative of the material being sampled.
