Impact resistance |
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 edgeFootnote (1) (top). |
Chemical resistance |
± 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%. |
