ISO 18543 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 units, laminated glass, or a combination of both.
The test method described in ISO 18543 is only applicable to chromogenic glazings that can be switched between different transmission states using an electrical stimulus. This test method is applicable to any electrochromic glazing fabricated for use in buildings such as indoors, windows, skylights, exterior wall systems and glazing exposed to solar radiation.
ISO 18543 on the accelerated ageing test and requirements for electrochromic glazings is useful for:
Electrochromic glazings perform several important functions in a building envelope, including:
Therefore, it is important to understand the relative serviceability of these glazings.
ISO 18543 is intended to provide a means for evaluating the durability of electrochromic glazings
ISO 18543 provides you with the rapid but realistic cycling between high and low light transmission states and environmental parameters that are typically used in weatherability tests such as simulated solar exposure and high temperature, which are realistic for the intended use of electrochromic glazings. ISO 18543 helps you manufacture high-quality electrochromic glazings.
