| Impact resistance |
— |
The cladding system shall be capable of withstanding the applied impact loads without deterioration in the performance or safety of the system. |
Pass |
| Acid rain resistance |
— |
The surface shall not have any defects and/or occurrences of new voids. |

| Wind load resistance |
— |
The cladding system shall be capable of resisting and transmitting to its points of support, the positive and negative forces, that are generated by the design wind loads without any fracture or permanent deformation of the surfaces resulting from such design wind loads. |
Pass |
| Durability |
— |
The durability of the cladding is assessed by observing changes in appearance (e.g., cracking, crazing) and by measuring the loss of flexural strength. |
Pass |
| Accelerated weathering resistance |
— |
No visual surface or physical change such as cracking, flaking or other deleterious effects after 2000 hours UV exposure |
Pass |
