"Tested for tough treatment: The BEKANT desk series have been tested according to the highest standards for professional office use (EN 527, ANSI/BIFMA X:5.5 for desks and EN14074, EN1730 and ANSI/BIFMA X:5.5 for conference tables) and meets our strict standards for quality and durability."
Galant's table tops are rebranded BEKANT recently, however it's the same stuff AFAIK.
