Just from the numbers, and Mark's guesses, I'd guess... Raumgewicht: 0.75-0.95 Specific Gravity >Zugfestigkeit: 120-140 N/mm^2 Compression parallel to grain >Druckfestigkeit: 55-82 N/mm^2 Compression perpendicular to grain >Biegfestigkeit: 115-160 N/mm^2 Static bending fiber stress proportional limit >Härte n.Brinell 12% Feuchtigkeit : H BII = 71 - 81 N/mm^2H BI = 30 - 35 >N/mm^2 Hardness/Brittle ness at 12% RH It would be nice to know, though. Can anyone lend us their German for a minute? Ron N
