the minimum cutting 300mm and longer with 2 faces/edges defect free,
except following 1-4.
Following defects shall be permitted on either face/edge:

1. Resin streak : one, 0.5mmW, 100mmL
2. Sloping grain : not restricted
3. Stain : insufficient to impair a natural finish
4. Surface checks : No specified number, 0.5mmW, 50mmL




F/J GRADE

Each piece yields 50% or better of its length in clear cuttings
within the minimum cutting 150mm or longer with 2 faces/edges
defect free, except following 1-4.

3. No.3 CUTTING 55% ~ 65%
4. F/J GRADE 5% ~ 10%

*The reason why wider boads could increase the value of the board in comparison to narrower boards. The wider width board is graded according to the overall defects present. A wider board could increase its value to the customer, if it is ripped down into a variety of narrower cuts, cutting around the defects present, and producing higher value cuts.
