Sampling may be from the right-hand side of the supplier’s vehicles (basic ad hoc sampling) or from the left-hand side (ad hoc sampling). The methods and tools of sampling are the same in both cases.
A cut perpendicular to the axis line is made in the selected specimen at a distance of at least 10 cm from the end (butt). The sample cut must reach the largest diameter of the sample (heartwood) and the sawdust chip thus obtained is collected and placed in a container used specifically for this purpose.
Particular care is taken to ensure that the collected sample does not contain other contaminants (water, chips of other material, etc.).
In case of road delivery, the number of samples should be 4 pcs per vehicle or 8 pcs on semi-trailers.
