: It explicitly states that it applies only to architectural security systems—like windows, doors, and barriers—and to Personal Protective Equipment (PPE) such as body armor. Increased Rigor

A plastic panel that stops a bullet when new but becomes brittle after two years of sun exposure will no longer pass certification.
