BOULES | Grain | Knots | Red coloration | Splits | Other particularities |
---|---|---|---|---|---|
F B-A | Straight-grained | Not accepted | Accepted if limited to 20 % of the board width |   | Accepted if limited to 30% of boards in a batch: intergrown sound knots, non-straight splits, bark pockets, sound dead knots. They will give rise to the usual volume reductions at the time of measurement. 70% of all boards in any batch must be free from any defects on one side. |
F B-AR | Definition as for FBA with no limits to red coloration, which must however be regular and not too dark. |   | |||
F B-1 | Tolerance of light curve in grain | Intergrown sound knots accepted in up to 50% of the boards | Limited to 25% of the width of the board | Non-straight splits, bark pockets and deterioration will give rise to the usual volume reductions at the time of measurement. Only one of these defects is acceptable on any one board. | Accepted, as long as 50% of the boards remain clear |
F B-1R | Definition as for FB1 with no limits to red coloration, which must however be regular and not too dark. |   | |||
F B-2 | Reasonable curve with slight presence of slope grain | Intergrown sound knots accepted in up to 70% of boards | Limited to 33% of the width of the board | Non-straight splits, bark pockets and deterioration due to fungal and insect attack are tolerated with volume reductions unless one board does not present more than two of these defects | Accepted, as long as 50% of the boards remain clear |
F B-2R | Definition as for FB2 with no limits to red coloration |   | |||
F B-3 |   | Intergrown sound knots accepted with no limit on the diameter |   |   | All other defects are accepted with no limit on the diameter. Bark pockets, rotten knots, cat's paws, stains and shakes will give rise to the usual volume reductions. |
SQUARE EDGED | Knots | Red heart | Other particularities |
---|---|---|---|
F F-A | Not accepted | Not admitted | Bow tolerance 15 mm/m |
F F-AR (3-4 clear sides freshly sawn) |
Definition as for FFA with no limits to red coloration. Red heart tolerated upon commercial agreement |   | |
F F-1 | On one side or edge 2 intergrown sound knots are accepted, limited to 25% of the pieces of the batch. These knots must not exceed 1/4 of the width of the piece or 20 mm | Not admitted | Bow tolerance 15 mm/m. All other defects or singularities on the other 3 sides are not admitted. |
F F-1R | Definition as for FF1 with no limits to red coloration |   | |
F F-2 | On each side and edge 3 intergrown sound knots are tolerated unless they are bigger than 1/3 of the width of the piece or 40 mm | Not admitted | Other defects are permitted except bark pockets, stain, rot, fungal attack, insect attack. Bow tolerance 15 mm/m. |
F F-2R | Identical to FF2 with no limits to red coloration |   |
