|
Hardness
|
Testing to ASTM 1037 procedures, bamboo displays an average hardness of 1642, which is harder than Red Oak and Rock Maple. Bamfox® Rustic Strand Woven Bamboo is harder than most Australian Species like Iron bark or Black Butt or Jarrah. Bamfox® Rustic Strand Woven Brinell hardness rating is 14.3.

|
Adhesive
|
With 0.02 mg formaldehyde per cubic meter of air, the adhesive off-gasses 6.5 times less formaldehyde than allowed under the stringent European (E1) standards, which are 0.13 mg per cubic meter of air. European standards are stricter than U.S. standards.

|
Dimensional Stability
|
Bamboo flooring produced a dimensional change coefficient of .00144 making it 2.5 times more stable than commonly used wood flooring.
|
|
|
Flammability
|
Using ASTM E648 Critical Radiant Panel Test, treated bamboo flooring passes with a Class 1 rating according to the NFPA "Life Safety Code" making it usable in all buildings.
|
|
|
Smoke Density
|
Testing to ASTM E622 where passing is 450 or less, bamboo flooring passes with a 270 rating in flaming mode, and a 330 rating in non-flaming mode.

Adhesive Specifications
|
With 0.02 mg formaldehyde per cubic meter of air, the adhesive used to laminate the bamboo strips which form Bamfox Bamboo flooring off-gasses 6.5 times less than allowed under the stringent European (E1) standards which are 0.13 mg per cubic meter of air. The European standards more strict than U.S. standards.
In November 1987, OSHA proposed the occupational standard for formaldehyde exposure be reduced from 3 parts per million (ppm) to 1 ppm, averaged over an 8-hour workday; this proposal became law. In May 1992, the law was amended with the formaldehyde exposure limit reduced to 0.75 ppm. (This information can be obtained through the Occupational Safety and Health Administration, Public Affairs Office, Room N3647, 200 Constitution Avenue, NW., Washington, DC 20210. Phone: 202-693-1999.) Given .75ppm regulations and .0155 for HIE adhesive product, HIE is 48 x less than the allowance by American standards.

Conversion to ppmv (Parts Per Million by Volume)
|
Conversions from 0.02mg of formaldehyde per cubic metre of air
to ppmv (Parts Per Million by Volume)
At ambient air pressure of 1 atmosphere and a temperature of 15.56°C (60°F):
0.02mg of formaldehyde per cubic metre of air = 0.0149 ppmv
At ambient air pressure of 1 atmosphere and a temperature of 21.11°C (70°F):
0.02mg of formaldehyde per cubic metre of air = 0.0152 ppmv
At ambient air pressure of 1 atmosphere and a temperature of 26.67°C (80°F):
0.02mg of formaldehyde per cubic metre of air = 0.0155 ppmv
The molecular weight of formaldehyde (30.03) was used in the conversions.
