Test block ! Only for testing the BLL with the test block !

• Wood chips: standard chips of wood (forest wood chips) according to EU-norm

CEN/TS 14961 class P16 and P45.

• Coarse chips: for coarse wood chips P45 but with fewer fines.

• Industrial chips: for industrial chips of wood without barks and fines (similar

P63)

Definition of wood chips classes

The stated numbers refer to the particle size that goes through round gaps of the

corresponding diametres (e.g. P16: 16 mm).

o P16 minimum 80% of the bulk is between 3,15 and 16 mm

o P45 minimum 80% of the bulk is between 3,15 and 45 mm

o P63 minimum 80% of the bulk is between 3,15 and 63 mm

Compression of wood chips

The BLL is calibrated for normally compressed wood chips. If the measured wood

chips are compressed to a much lesser or greater extent, this will cause measuring

imprecisions. Normally compressed wood chips are defined in norm CEN/TS 15103

(determination of the bulk density).

3.0 DETERMINATION OF THE MATERIAL REFERENCE MOISTURE

The principle is a comparison measurement with the dehydration method according

to CEN/TS 14774. Take the measured sample and weigh it. Dry it out in an oven

and weigh it again.
