ASTM E2355 – Standard Test Method for Measuring the Uniformity of an Absorptive Electrochromic Coating on a Glazing Surface (Withdrawn 2019)

1.1 The test described is a method for measuring the uniformity of an absorptive electrochromic coating (ECC) in a static colored or bleached state on a glazing surface, which is or will be one of two or more glazings in a preassembled permanently sealed insulating glass unit (IGU).

1.2 The test method is applicable only for layered (one or more active coatings between the TCOs) absorptive ECCs on vision glass (superstrate and substrate) areas planned for use in buildings, such as glass doors, windows, skylights, and exterior wall systems. The layers used for electrochromically changing the optical properties may be inorganic or organic materials between the superstrate and substrate and may include laminates.

1.3 The test method is not applicable to other types of coatings on vision glass with other chromogenic coatings that cannot be held in a static colored or bleached state.

1.4 The test method is not applicable to IGUs that will be constructed from superstrate or substrate materials other than glass.

1.5 The test method is not applicable for measuring the uniformity of ECC coatings during the coloring or bleaching processes.

1.6 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.

1.7 There is no comparable International Standards Organization Standard.

1.8 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory requirements prior to use.
