ISO 3536:2026

Overview

ISO 3536:2026 - Road vehicles - Safety glazing materials - Vocabulary is an internationally recognized standard developed by the International Organization for Standardization (ISO). This document provides a comprehensive and harmonized set of definitions and terminology regarding safety glazing materials used in road vehicles. By standardizing the vocabulary, ISO 3536:2026 facilitates clear communication and uniform understanding among stakeholders across the automotive and glass manufacturing industries, regulatory bodies, and enforcement agencies.

Safety glazing materials play a critical role in vehicle occupant protection, visibility, and durability. With advancements in automotive design and technology, having a current, shared vocabulary is essential for ensuring compliance with safety requirements and enabling innovation.

Key Topics

• Safety glazing material: Definitions and types of materials constructed or treated to minimize injury risk to vehicle occupants during impact.
• Types of glass and plastics:
  • Toughened (tempered) safety glass
  • Laminated safety glass
  • Glass-plastic and plastic safety glazing materials
  • Double glazed units and double windows
• Components and features:
  • Interlayers in laminated glass
  • Shade bands and opaque obscuration zones
  • Security and bullet-resistant glazing
• Optical properties and measurements:
  • Luminous transmittance and reflectance
  • Optical deviation, distortion, secondary images
  • Vision area, primary vision area, and transparent areas
• Glazing design characteristics:
  • Curved and flat pane definitions
  • Height of segment and radius of curvature
  • Design glazing outline and installation (rake angle)
• Testing and performance criteria:
  • Test specimens and head injury criteria (HIC)

Applications

The standardized terminology defined in ISO 3536:2026 is essential for several key automotive industry applications:
