Notes to Table 4.1.2.5:

Footnote 1

This test was conducted only on planks with solid sections. Only the specified planks (with solid sections) may be used as stair treads.

Return to footnote 1 referrer

Footnote 2

Test results are for a 50°C test condition for stair stringers spaced at 230 mm o.c. Three specimens were submitted for each test.

Return to footnote 2 referrer

Footnote 3

Applied through a 75-mm-diam disk positioned at the centre line of the plank and midway between stringers.

Return to footnote 3 referrer

Footnote 4

Applied through a 38-mm-diam disk positioned along the outside edge of the nosing at the stringer location.

Return to footnote 4 referrer

Footnote 5

Although the deflection is slightly higher than the allowed limit, the applied ultimate load was 150% higher than the minimum required ultimate load. Therefore, this deflection result was deemed acceptable.
