When inspecting Plexiglas, what should be checked for?

When inspecting Plexiglas, the focus should be on identifying crazing and discoloration. Crazing refers to the formation of tiny, fine cracks or surface defects that can develop due to stress, impact, or prolonged exposure to UV light. This condition can compromise the structural integrity and optical clarity of Plexiglas, making it critical to detect during inspections.

Discoloration may occur due to environmental factors, chemical exposure, or degradation over time, which can also affect visibility and lead to further degradation. Both crazing and discoloration can significantly diminish the performance and safety of the material, especially in applications where clear visibility is essential, such as in aircraft windows or cockpit panels.

Overall, looking for these defects helps ensure the Plexiglas continues to function effectively and meets safety standards required in aviation contexts.
