Penetration refers to the amount of agent per cubic meter; the NTRA EU standard specifies 12 kilograms of agent per cubic meter. The sapwood part of the tree can be completely saturated with the high-pressure treatment agent. The core of a tree contains resin, which prevents preservatives from penetrating; however, the resin itself has antiseptic properties
