1 Scope This document specifies the accelerated ageing test and requirements for electrochromic ( EC ) glazings. The test method described in this document is only applicable to chromogenic glazings that can be switched using an electrical stimulus from high to low transmission states and vice versa. 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 vision glass (e.g. insulating glass unit, laminated glass) for use in buildings such as doors, windows, skylights and exterior wall systems and glazing exposed to solar radiation. The layers used for constructing the EC glazing and for electrochromically changing the optical properties can be inorganic or organic materials.
