This standard provides guidelines and recommendations for the sampling of wood chipsintended for the production of wood pulps.

This standard provides guidelines and recommendations for the sampling of wood chips intended for the production of wood pulps. The procedure covers both the selection of the gross sample from a lot or shipment, mixing the sample, and the preparation of individual samples for laboratory testing from the gross sample.
