Notes:

Footnote 1

Note that the increase in creep in mm at 20°C and 30°C in Tables 4.2.1.1 and 4.2.2.1 is small and within the error of measurement. This same minor deviation is reflected in Table 4.2.3.1 as % increase, which amplifies the slight deviation. In addition, note that the irrecoverable creep in Table 4.2.3.1 met the criteria, which is an important performance factor. These test values are deemed to pass the target criteria for use in OSB sheathing panels.

Footnote 2

Note that the increase in secondary creep in mm between the values recorded at 20°C and 30°C reported in Tables 4.2.1.1 and 4.2.2.1 is small and within the error of measurement. This minor deviation is reflected in Table 4.2.3.1 as % increase, which amplifies the slight deviation. In addition, note that the irrecoverable creep in Table 4.2.3.1 met the criteria, which is an important performance factor. These test values are deemed to pass the target criteria for use in OSB sheathing panels.
