Flooring & Furniture
This user group provides technical information for manufacturers, woodworkers, importers and distributors of tropical woodflooring, decking, wooden cabinets, furniture and crafts. Depending on local interest, this user group could support joint programs with other user groups to source, develop and promote value-added products with lesser-used tropical timbers.
ITTO seeks expressions of interest from local producer organizations, woodworker groups and senior technical specialists to participate in the editorial panel for this user group. Please contact: Ramon Carrillo, firstname.lastname@example.org
- ABC of Website - Janka Hardness, Techology Keys - "The Janka hardness of wood samples in air dry condition (12%M.C.), is used for species searches and comparisons.
Refers to the load required to embed a steel ball half inch in diameter to half its thickness on the side grain or the end grain.
The sorting ranges used by the original database are used. Values are based on results of Janka side grain tests expressed in kgf as follows. (test protocol and machines explained elsewhereHardness / Janka)
Very low: Less than 305 kgf
Medium: 305 to 610
Fairly high: 610 to 915
High: 915 to 1220
Very high: Over 1220"
