16 - PRODUCT OR PIECE SPECIFICATIONS
Use the following criteria for determining the classification of dead1
logs, use in future contracts, and for current log scale contracts that
have the classification of “dead” logs. Use this criteria for all
species.
1. In the judgement of the scaler2, the log must be from
a dead tree or a dead portion of a live tree that was dead
when cut3, and
2. The segment must contain a deductible defect in the
scaling cylinder due to at least one of the following causes
that has originated in the sapwood.
a. Rotten sapwood, of the true sapwood variety, and
not associated with fire scar, lightening scar, frost
crack, catfaces, and so forth. 4
b. Weather checks.
c. Massed wormholes (large variety).
1
Any timber which does not meet the dead criteria is considered
"live".
2
Contracting Officer must notify scaler of any "live" material
which due to delay in delivery to the mill appears to be dead.
3
This is usually evident by the lack of pitch beads in the sapwood
on the cut end.
4
See chapter 30 for log defects and deductions.
