ISO 12543-2:2021

Overview

ISO 12543-2:2021 is an international standard from ISO’s series on glass in building, specifically focusing on laminated safety glass. This document establishes the performance requirements for laminated safety glass, providing guidelines that help ensure product safety, durability, and compliance for use in construction. The standard defines aspects such as impact resistance, durability under various environmental conditions, and proper designation. These requirements are essential for manufacturers, suppliers, architects, building professionals, and regulatory authorities to maintain quality and safety in glazed building applications.

Key Topics

ISO 12543-2:2021 addresses several important aspects of laminated safety glass performance:

• Impact Resistance
  Specifies performance under pendulum impact tests, distinguishing laminated safety glass from standard laminated glass.

• Durability Testing
  Sets out procedures for high-temperature, humidity, and radiation tests to assess how laminated safety glass withstands environmental aging.

  • Short and long high-temperature test options
  • Humidity tests for both general and fire-resistant laminated safety glass
  • Radiation tests for exposure to solar effects

• Component Parts
  Reference to ISO 12543-1 for definitions and descriptions of laminated glass components.

• Dimensions and Edge Finishing
  Requirements for dimensions and edge finishing are specified in ISO 12543-5.

• Acoustic Properties
  Option for testing acoustic insulation performance, referencing ISO 22897 and ISO 16940.

• Appearance Standards
  Guidance on acceptable appearance and surface condition is found in ISO 12543-6.

• Product Designation
  Specifies how laminated safety glass should be designated by type, thickness, and dimensions, making identification clear and consistent.

Applications

Laminated safety glass manufactured and tested in accordance with ISO 12543-2:2021 provides robust performance for a range of building and architectural applications. Practical uses include:

• Building Facades and Glazing
  Ensures safety and structural integrity in exterior and interior building elements.

• Windows and Doors
  Used where enhanced impact resistance and security are required, such as in schools, hospitals, offices, and residential buildings.

• Overhead and Sloped Glazing
  Prevents shattering hazards in areas such as skylights and canopies.

• Balustrades and Partitions
  Delivers sturdy, safe barriers while maintaining visibility.

• Fire-Resistant Installations
  Covers specialized applications where fire-resistant laminated safety glass is required by building codes.

Implementing ISO 12543-2:2021 helps organizations demonstrate compliance with international norms, support risk reduction in the built environment, and facilitate global trade in glass building products.
