GDI 303: Discoloration Defects

GDI 303 covers Heavy Pitch and Seams, two discoloration defects that require added instructions for proper grade application.

Syllabus

GDI 303: Heavy Pitch for Finish and Premium

In the grades of Finish and Premium there may be some tear drop like accumulations of heavy pitch at the black knots. This will be limited to pocket size in a board free of most other defects.

In Premium, there may be some heavy pitch accumulated with a bark seam. This will be measured as part of the allowable bark seam.

GDI 303: Seams

If a seam extends to an edge of a board, and is open from one wide face through the edge to the other wide face, it is limited as an edge break.

Open voids in a bark seam will be limited as holes.
