Scratches and surface marks on glass are a common concern in construction projects. The key question is:

When is a scratch acceptable, and when does it require glass replacement?

The answer is not subjective. It is defined by European standards (EN), which set clear acceptance criteria for glass surfaces.

Not Every Scratch Is a Defect

According to European specifications:

• Certain surface marks and scratches are within acceptable tolerances
• Evaluation depends on
  – the type of glass
  – the installation location
  – the viewing distance
• Not every visible mark justifies glass replacement

Proper assessment must always be based on standards—not personal judgment.
