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
08-11-2006Jozef De Corte
WHAT in INDUSTRY ?
• APPLYING PRATICAL PRESCRIPTIONS• ATG = Belgian Technical Agreements• INTERNAL CONTROL• EXTERNAL CONTROL - INSPECTION• CERTIFICATION ( not always )
08-11-2006Jozef De Corte
CRITERIA for ATG
• Knots• Splits • Pith• Annual growth rings• Slope of grain• Deformation• MC• Wane• Appearance of stain and mould• etc
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
STRENGHT RELATION
• Belgian ���� EN 1912
• S6 => C18• S8 => C24• S10 => C27 ( future => C30 )
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
PARTICLE BOARDS
• Reference doc is Belgian ATG– see EN 13986
• Technical requirements– strength
• Fysical requirements– MC; Swelling; etc
• Chemical requirements– Emissions formaldehyde
08-11-2006Jozef De Corte
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
08-11-2006Jozef De Corte
OTHERS
• PRESERVATIVE WOOD TREATMENT– Reference doc is Belgian ATG
• WAITING for CE - MARKING– WINDOWS– DOORS– etc
08-11-2006Jozef De Corte
CONCLUSION
• QUALITY CONTROL IS DONE TO FULFIL REQUIREMENTS– national for the moment– European in the future
• VERY LITTLE SPONTANIOUS CONTROL
• NO RESEARCH IN PROGRESS
