| General quality classification
When talking about quality standards in wood appereance, it is not quite obvious in the world of parquet
flooring. There exist some definitions of prime and quartersawn but for the rustic qualities it's mostly
confusing and difficult to compare between manufacturers. That's why we adhere to the standards of the
French APECF for oakwood. This classificiation qualifies the wood according to its exterior characteristics: |
| |
QFQ | Quartersawn, no defects, no decolorations, straight grain. Also available as QFQ 1bis, see QF1b. |
QF1a | Visible side without defects, on 20% of the boards, a maximum of one knot of maximum 10 mm is allowed
per length of 1 m (shorter planks accordingly). Straight grain, no sap, heartwood, crosswood. Compare
to 'prime'. |
QF1b | Up to 2 sound knots of maximum 12 mm per running meter allowed, grain mostly straight, no sap, heartwood,
decoloration, crosswood, insectholes, deformations. Compare to 1bis. |
QF2 | Unlimited small knots allowed plus 3 sound knots as a maximum per running meter with a maximum diameter
of 25 mm or 1/3 of the plank's widht (prevails which is more severe). Shifting grain and small
decoloration of the wood allowed. No sap, heart or non natural decoloration. |
QF3 | Unlimited small knots allowed plus 3 sound knots per running meter which are maximum half the plank
widht in diameter, limited to 40 mm. Shifting grain and natural decoloration of the wood, no sap,
heartwood allowed. |
QF4 | All defects allowed except sapwood; unlimited knots, small fillable gaps, cracks, decoloration
uneven thickness and widht (small variation allowed), wormholes in mature wood, etc. |
QF5 | All that is not suitable for the other qualities. No sap wood but else every defect allowed like insect holes
cracks, open and closed nuts, colour faults. Because this is very nervous wood, no guarantee is given
towards constant measure; thickness and width may differ. Some surfaces may not be machined. |
Spint | All previous standards are without sap on the visible side, on a small number of planks a trace of
sap is allowed on the backside, up to maximum 60 % of its thickness. |
