​ECE Regulation R43 was developed by the United Nations Economic Commission for Europe (UNECE) and specifies the requirements for safety glazing materials used in vehicles. The purpose of this regulation is to ensure that all glazing components—such as side windows and windshields—provide adequate visibility, sufficient durability, and the necessary protection for vehicle occupants.

This regulation covers various aspects of safety glazing, including material properties, optical quality, and impact resistance.

​

Key elements of ECE R43 include:

• Material Requirements:
  The regulation defines the types of materials that can be used for automotive glazing and ensures that they meet the required standards for strength, durability, and resistance to environmental factors such as UV radiation and temperature variations.
  

• Optical Qualities:
  ECE R43 sets strict standards for the optical quality of glazing to ensure transparency and distortion-free visibility. These standards include requirements for light transmission, refractive properties, and the absence of visual defects.
  

• Impact Resistance:
  The regulation mandates rigorous testing to evaluate the impact resistance of glazing materials, ensuring they do not shatter dangerously in accidents or similar conditions. This includes tests such as stone impact, headform impact, and fragmentation pattern analysis.
  

• Marking and Certification:
  Manufacturers are required to mark all safety glazing materials with an appropriate code indicating compliance with ECE R43. This marking serves as proof of conformity with safety standards and provides assurance to consumers.
