Penetration of preservative Wood taken as sample
Heartwood No treatment required Figure 1 — Sampling location in round and part-round wood if a defined penetration depth is required If the requirement is for complete penetration, it is necessary for the borer to penetrate to the geometrical centre of the cross-section (see Figure 2).
Figure 2 — Sampling location in round and part-round wood if complete penetration is required

Figure 3a - Sampling location in samples containing both sapwood and heartwood Figure 3b - Sampling location in samples consisting entirely of sapwood or if it is impossible to identify any heartwood before sampling Figure 3 — Sampling location in sawn and profiled wood if a defined penetration depth is required If full sapwood penetration is required, borings shall be taken, as far as possible, in the radial direction and where the depth of sapwood is greatest. From sampling units consisting entirely of sapwood or if it is impossible to identify any heartwood before sampling, the boring shall be taken equidistant from the sides and perpendicular to the face being sampled to a depth of half the thickness of the sampling unit (see Figure 4).
