chunkwood
wood cut ci brooken with sharp cutting devices in which most of the matenal has a typical particle length. substantially longer and more coarse than wood chips
NOTE Chunkwood has a typsal length o150 mm to 150 mm.
4.39
combined simple
sample consisting of all the increments taken from a sub-lot
NOTE The increments may be reduced by division before being added to the combined sample.
4.40
common sample
sample collected for more than one intended use
(Adapted from ISO 13909:2001)
4.41
complete tree
harvested tree, Induding limbs and root system
NOTE See also whoJe Iree
4.42
contamination
make Impure by exposure to or addition of a poisonous or polluting substance to a fuel
4.43
cork residues
biomass reskiues from cork production
4.44
critical control point
point within or between processes at which relevant properties can be most readily assessed
NOTE Critical control points also otter the greatest potential for quality improvement.
4.45
crop production residues
agncultural residues originating from crop production, harvesting, and processing in farm areas
NOTE It andudes among others wood, straw, stalks. and husks.
4.46
cross-cut ends
short pieces of woody biomass which occur when the ends of logs or sawn timber are cross cut off, with or without bark
4.47
customer
client
organization or person that receives a product
[Adapted from EN ISO 9000:2005]
4.48
cut biofuel
solid bio(uel cut into pieces
NOTE See also chuntrwood, firewood, ctic,ed straw, and smawood.
4.49
cutter chips
wood chips made as a by-product of the wood processing industry, with or without bark
4.50
delivery agreement
contract for fuel trade, which specifies ag. origin and source. quality and quantity of the fuel, as well as deIivw, temis
4.51
delivery lot
soJid bio fuel batch on which the essential quality requirements for solid b.ioft,el are focused
NOTE I The deftveiy lot can be an mdividual delivery lot, which is an agreed quantity of solid biatuel (e.g. a package, shipload or truck load), or continuous delivery, where several loads are delivered to the end-user during an agreed period of time (usualy daffy or weeldy delivery).
NOTE 2 In contmuous delivery, the delive,y lot is the emount 01 solid biofuel detivered during a specified period of time. e.g.
24 h. isiless otherwise agreed by supplier and end-user. if the delivery lot In continuous delivery is more than 1 500 m3 — 2 000 m’ Ni 24 h. N is reccininended that it should be divided Nito two or more inckvidual lots.
4.52
demolition wood
used wood arising from demolition of buildings or civil engineering installations
[Adapted from EN 13965-1:20041
4.53
densifled biofuel
compressed biofuel
solid biofuei made by mechanically compressing biomass to increase its density and to mould the solid bioluel into
a specific size and shape such as cubes, pressed logs. biofuel pellets or biiofuel bnquetfes
NOTE See also biiofuet briquette and blot uel pellets.
4.54
density
ratio of mass to volume
NOTE 1 It will always be stated whether the density refers to the density of individual partides or to the bulk density of the material and whether the mass of water m the materiel is induded.
NOTE 2 See also basic densy, bulk densliy and pftrticle densi.
4.55
dry ash free
dry ash free basis
calculation basis Ni which the solid fuel Is tree from moisture and inorganic matter
4.55
dry
dry basis
calculation basis Ni which the solid fuel is tree from moisture
(Adapted front ISO 121 3-2:1992)
4-57
dry matter
matenal after removal of moisture under specific conditions
4.58
dry matter content
portion of dry matter in the total materiall on mass basis
NOTEExpressed as a percentage of the total mass of the solid biofuel.
4.59
edgings
parts of woody biomass which occur when trimming sawn timber and which show a remainder of the originalrounded surface of the tree, with or without bark
4.60
end-user
consumer (private person, enterprise, utility, etc.) using fuel for energy purposes
4.61
energy crops, fuel crops
woody or herbaceous crops grown specifically for their fuel value
NOTE 1See also energy forest trees,energy grass,energy plantation trees.NOTE 2 Fuel crops is a not recommended synonym.
4.62
energy density
ratio of net energy content and bulk volume
NOTE The energy density is calculated using the net calonific value determined and the bulk density.
4.63
energy forest trees
woody biomass grown specifically for its fuel value in medium to long rotation forestry
4.64
energy grain
grain used for energy purpose.
