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:

 
QFQQuartersawn, no defects, no decolorations, straight grain. Also available as QFQ 1bis, see QF1b.
QF1aVisible 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'.
QF1bUp 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.
QF2Unlimited 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.
QF3Unlimited 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.
QF4/5All defects allowed except sapwood; unlimited knots, small fillable gaps, cracks, decoloration uneven thickness and widht (small variation allowed), wormholes in mature wood, etc.
SpintAll 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.
