Key Features

• Comprehensive Testing Protocols: The standard outlines rigorous testing procedures to simulate long-term ageing effects on electrochromic glazings, ensuring they meet high-performance standards.
• Durability Assurance: By adhering to the guidelines in BS ISO 18543:2021, manufacturers can guarantee the longevity and reliability of their electrochromic glazing products.
• Industry Compliance: This standard helps manufacturers and builders comply with international regulations and quality benchmarks, promoting safety and efficiency in building projects.

Why Choose BS ISO 18543:2021?

Electrochromic glazings are a revolutionary technology in the building industry, offering dynamic control over light and heat transmission through windows. However, their performance can degrade over time due to environmental factors. The BS ISO 18543:2021 standard is essential for ensuring that these advanced materials maintain their functionality and aesthetic appeal throughout their lifespan.

Accelerated Ageing Test

The accelerated ageing test described in this standard is designed to replicate the long-term effects of environmental exposure on electrochromic glazings. This includes factors such as UV radiation, temperature fluctuations, and humidity. By simulating these conditions, the test provides valuable insights into the durability and performance of the glazing materials.

Requirements and Criteria

The standard sets forth specific requirements and criteria that electrochromic glazings must meet to be considered compliant. These include:

• Optical Properties: Ensuring that the glazing maintains its ability to modulate light transmission effectively.
• Mechanical Integrity: Verifying that the glazing remains structurally sound and free from defects such as delamination or cracking.
• Environmental Resistance: Confirming that the glazing can withstand prolonged exposure to environmental stressors without significant degradation.

Benefits of Compliance

Adhering to the BS ISO 18543:2021 standard offers numerous benefits for manufacturers, builders, and end-users:

• Enhanced Product Quality: Products that meet the standard's requirements are proven to be of higher quality and reliability.
• Increased Marketability: Compliance with international standards can enhance a product's appeal in the global market.
• Customer Confidence: End-users can trust that compliant products will perform as expected, providing peace of mind and satisfaction.

Conclusion

The BS ISO 18543:2021 standard is an invaluable resource for anyone involved in the production, specification, or use of electrochromic glazings in building applications. By following the guidelines and requirements set forth in this standard, stakeholders can ensure that these innovative materials deliver consistent performance and durability, contributing to the overall success and sustainability of building projects.

Invest in the future of building technology with the BS ISO 18543:2021 standard, and ensure that your electrochromic glazing products stand the test of time.

BS ISO 18543:2021

This standard BS ISO 18543:2021 Glass in building. Electrochromic glazings. Accelerated ageing test and requirements is classified in these ICS categories:

• 81.040.20 Glass in building

This document specifies the accelerated ageing test and requirements for electrochromic glazings intended to either control direct or indirect solar transmission, or both. The electrochromic glazings can be assembled as insulating glass unit, laminated glass or combination of both.

The test method described in this document is only applicable to chromogenic glazings that can be switched between different transmission states using an electrical stimulus. This test method is not applicable to other chromogenic glazings such as photochromic and thermochromic glazings, which do not respond to electrical stimulus.

This test method is applicable to any electrochromic glazing fabricated for use in buildings such as in doors, windows, skylights, exterior wall systems and glazing exposed to solar radiation. The materials used for constructing the electrochromic glazing and for electrochromically changing its optical properties can be inorganic or organic materials.
