Quality control in BELGIUM for wood and wood products

–Research–Industry


wood chain

• forestry• sawmilling = first transformation• wood industry = second transformation

– furniture– panels– construction elements– packaging– others


FOREST RESOURCES

• Belgian area: 3 052 600 ha

• Forest 646 000 ha• wooded land 26 000 ha• total area: 672 000 ha

• land area: 0,30 ha / inhabitant• forest area: 0,07 ha / inhabitant

UNIVERSITIES & INSTITUTES

• CTIB – TCHN in Brussels– Practical research– Certification– Inspections in industry

• UGent– strength caracteristics of poplar

• UCL in Louvain La Neuve– wood quality of european Douglas


RESEARCH• 1983 – 1987 : CTIB – TCHN

PhD ir. H. Coppens• determination of the mechanical

properties of Belgian wood• by measuring the proper frequency of

sawn timber• Non destructive method• Apparatus: Grindo Sonic• Correlation with mechanical testing


WHAT in INDUSTRY ?

• APPLYING PRATICAL PRESCRIPTIONS• ATG = Belgian Technical Agreements• INTERNAL CONTROL• EXTERNAL CONTROL - INSPECTION• CERTIFICATION ( not always )


CRITERIA for ATG

• Knots• Splits • Pith• Annual growth rings• Slope of grain• Deformation• MC• Wane• Appearance of stain and mould• etc


STRESS GRADED SOFTWOOD

• Reference doc is Belgian ATG• Approval by national body• Technical requirements

– strength• CE marking based on EN 14081

– from 1 - 09 - 2007• Inspection by CTIB - TCHN


STRENGHT RELATION

• Belgian �� EN 1912

• S6 => C18• S8 => C24• S10 => C27 ( future => C30 )


GLUED LAMINATED BEAMS• Reference doc is Belgian ATG

– see EN 386 and EN 14080• Approval by national body

• MC - overall range: 8 => 15 %- max range in beam: 4 %

• Mech. Strength => S6 or betterif in accordance with design values

• Inspection by CTIB - TCHN


TRUSSES

• Reference doc is Belgian ATG– see EN 14250

• MC � 30 % (in existing situation)( EN 14250 � 22 % )

• Strength: free choice if accordance with the design values

• Inspection by CTIB - TCHN in production


LOG BUILDING KITS

• Reference doc is Belgian ATG– or ETA see ETAG 012

• Approval by national body• MC : 12 to 14 %• Strength: => S6 or better• in accordance with design values• Inspection by CTIB - TCHN


TIMBER FRAME BUILDING KITS

• Reference doc is Belgian ATG– or ETA see ETAG 07

• Approval by national body• MC : no specification • Strength: vertical elements => S6• horizontal elem. => S8 • Inspection by CTIB - TCHN


FIRE RESISTING DOORS• Production of prototype• Fire test on prototype• Minimum requirements in according

with results• Density classes of wood

( � 400 kg/m3 or > 400 kg/m3 )• MC – maximum and range• Conformity with prototype

( technical design )


FLOORING

• Quality aspectsSTANDARD EN 13228 and othersonly as a volantary standardno external inspection

• Safety aspectsin frame of EN 14342


PARTICLE BOARDS

• Reference doc is Belgian ATG– see EN 13986

• Technical requirements– strength

• Fysical requirements– MC; Swelling; etc

• Chemical requirements– Emissions formaldehyde


DRYING of WOOD

• NO OFFICIAL REQUIREMENTS• NO INSPECTION

• PROMOTION to use EN-STANDARDS• but not easy to convince the drying

companies and the end users


OTHERS

• PRESERVATIVE WOOD TREATMENT– Reference doc is Belgian ATG

• WAITING for CE - MARKING– WINDOWS– DOORS– etc


CONCLUSION

• QUALITY CONTROL IS DONE TO FULFIL REQUIREMENTS– national for the moment– European in the future

• VERY LITTLE SPONTANIOUS CONTROL

• NO RESEARCH IN PROGRESS
