No evidence of cracks or fissures when tested for impact at the perforated and non-perforated specimen face (sides) or the solid wide edge (top).

The 100 mm (4 in.), 150 mm (6 in.) and 200 mm (8 in.) specimens met the requirements. The 250 mm (10 in.) specimen met the requirements for both faces (sides), but did not meet the impact requirements for the solid wide edge^{Footnote (1)} (top).

± 2% maximum weight change

The specimens met the requirements when exposed to 12 different potentially damaging chemicals. Results ranged from a weight change of 0.09% to 0.15%.

The footing form and its accessories must remain within 10 mm of their original position after concrete placement and hardening.

The product met the requirements. A maximum displacement of 4.72 mm was observed.

No measurable leakage of concrete through the form.

The product met the requirements. No leakage of concrete through the form was observed.

The form must resist the anticipated loads imposed by the concrete placement.

The product met the requirements. The product resisted the loads imposed by the placement of concrete.

Comparative analysis to corrugated polyethylene pipe standard BNQ 3624-115, which has a minimum perforation area of 32 cm²/m.

The product met the requirements and has a total perforation area of 34.3 cm²/m for all product sizes.
