Footnote 3

Performance result allowed based on the manufacturer's gapping installation instructions.

Return to footnote 3 referrer

Footnote 4

Performance result allowed based on the full-scale structural impact test results.

Return to footnote 4 referrer

Footnote 5

Performance result based on testing at 400 mm o.c. support span width. As a result of failure to meet the requirement, the allowable support span was reduced to 300 mm o.c.

Durability -MOE	Mean percentage losses in MOE and MOR after UV exposure and accelerated aging must be less than or equal to spruce lumber.	21.4	39.9^{Footnote (1)}
Durability - MOR		27.9	15.3
Decay resistance - % loss in weight	Mean percentage losses in weight and compressive strength after exposure to decay-causing fungi must be equal to or better than spruce heartwood.^{Footnote (2)}	Pass
Decay resistance - compressive strength		Pass
Termite resistance	Rating must be equal to or better than preservative-treated wood conforming to CSA 80.1-M97.	Pass

Results of Testing the Durability, Decay, Termite and Slip-resistance Properties of the Product
Property		Requirement	Result Parallel to Planks	Result Perpendicular to Planks
Slip resistance dry condition	longitudinal planks	> 0.5	0.3^{Footnote (3)}	0.3^{Footnote (3)}
Slip resistance wet condition	longitudinal planks	> 0.5	0.4^{Footnote (3)}	0.5

Notes:

Footnote 1

Performance result based on testing at 400 mm o.c. support span width. As a result of failure to meet the requirement the allowable support span was reduced to 300 mm o.c.

Return to footnote 1 referrer

Footnote 2

Decay resistance results were obtained using southern yellow pine, sweetgum and Amine copper quaternary (ACQ) treated wood; results, although not in strict conformance with the Technical Guide, deemed acceptable based on the installation height stipulated in the Conditions and Limitations section of this Report.

Footnote 3

These criteria may not meet all occupant expectations. Performance result allowed for the intended use, as the slip resistance is less than the reference value. The manufacturer may be contacted for further information.
