scope:

This guide provides the recommended sequence for using the referenced ASTM test methods for assessing the durability of absorptive electrochromic coatings (ECCs) within sealed insulating glass units. Cross sections of typical electrochromic windows (ECWs) have three to five-layers of coatings that include one to three active layers sandwiched between two transparent conducting electrodes (TCEs, see Section 3). Examples of the cross-sectional arrangements can be found(Footnote 2) in "Evaluation Criteria and Test Methods for Electrochromic Windows." (For a list of acronyms used in this Standard, see Appendix X1, Section X1.1).

This guide is applicable only for layered (one or more active coatings between the TCEs) absorptive ECCs on vision glass (superstrate and substrate) areas planned for use in IGUs for 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.

The ECCs used in this guide will ultimately be exposed (Test Method E 2141) to solar radiation and deployed to control the amount of radiation by absorption and reflection and thus, limit the solar heat gain and amount of solar radiation that is transmitted into the building.

This guide is not applicable to other types of coatings on vision glass with other chromogenic coatings, for example, photochromic and thermochromic coatings.

This guide is not applicable to IGUs that will be constructed from superstrate or substrate materials other than glass.

The test methods referenced in this guide are laboratory test methods conducted under specified conditions.

The values stated in metric (SI) units are to be regarded as the standard.

There is no comparable International Standards Organization Standard.

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.
