Two samples of the three-ply laminated Oak Hardwood Flooring
(nominal thickness 13.5mm) were tested to the American National
Standard ANSJ/HPVA HP- I-2000 Hardwood plywood & Veneer
Association for Hardwood and Decorative Plywood for Adhesive
Bond Durability. Testing was conducted under two separate
adhesive Bond Types including Technical/Type I and Type
II. The first, having water resistant exterior-use durability.
The test for this included a cyclic boil/oven dry exposure
followed by shearing the glue line. And the second (Type
II) is rated for interior-use only. The test for this was
a cyclic soak at 24± 3 C followed by oven drying
and examining for delamination at the glue line after each
cycle. Ten specimens were tested from each sample for each
durability test.
Technical/Type I Requirements- Minimum tensile shear loads
are required depending on the percentage of fiber pull at
the glue line. For the tests conducted in this case, all
of the specimens delaminated at the glue lines completely
after the first boil/dry cycle. This is considered a failure
for rating this product under this durability.
Type II Requirements-Minimum amounts of glue line delamination
are required after each cycle. No delamination resulted
after completion of two cycles. This is considered passing
for rating this product under this durability.
