Dimensional Stability:
During a linear expansion/contraction test program in which the bamboo planks were subjected to a 50% relative humidity change over a 48h period. The bamboo showed a change in width of 0.06% and thickness change of 0.54%. No sign of delamination was detected (Ortech Corporation).
 

Internal Bond Strength:
The internal bond strength of bamboo was determined to be 2107 Newtons (Ortech Corporation).
 

Coefficient for dry Contractedness:
The radial direction was tested to be 0.138 and the chord direction was 0.149 (Middle-Southern Woods University).
 

Abrasion Resistance:
According to ASTM 5230 "Taber Abrasion Test", the wear index for Silkroad™ bamboo is 270 (Forintek Canada Corp.).
 

Janka Ball Hardness:
Silkroad™ bamboo plank flooring was determined to have an average hardness rating of 2,113 using the ASTM D1037 Hardness Test. The following are the results of individual hardness (lbs) tests performed specifically on each Silkroad bamboo flooring grain and colour.

 

TVOC Testing:
Results from the ASTM D5116-90 "Standard Guide for Small-Scale Environmental Chamber Determinations of Organics from Indoor Materials/Products", indicate that the emission rate for total volatile organic compounds (TVOC's) was 0.017 mg/m².h. The Ecologo™ guideline is 0.05 mg/m² (Ortech Corporation).
 

Formaldehyde Testing:
According to the results from ASTM D5116-90 "Standard Guide for Small-Scale Environmental Chamber Determinations of Organics from Indoor Materials/Products", the formaldehyde emission rate was 0.033 mg/m².h. The air quality criteria of Canadian Carpet Institute is 0.05 mg/m².h (Ortech Corporation).
