units with a transport packaging that is suitable for convenient load securing.”

QUANTIFIED RIGIDITY PROVED BY CERTIFICATE
F t t b d h i ti f t l dFor cargo transport by road: harmonisation of control procedures
Look for cargo securing solutions and make sure:
Products are not damaged by lashings
Products are not damaged under inertia forces
Conform EU packaging directive
Safety during transport
No waste of time for lashing
No unsafe situations during lashing

Conclusion after 2000 acceleration testsall load units can be rigidifiedgacceleration tests can help to reduce packaging cost
Conclusion after 2 years of optimized transport packagingdamage of transported goods is reduced by 25 to 50%damage of transported goods is reduced by 25 to 50%acceleration tests available in Belgium, Germany, Spain,
