1、Designation: E 2355 04Standard Test Method forMeasuring the Uniformity of an Absorptive ElectrochromicCoating on a Glazing Surface1This standard is issued under the fixed designation E 2355; the number immediately following the designation indicates the year oforiginal adoption or, in the case of re
2、vision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 The test described is a method for measuring theuniformity of an absorptive electrochromic coatin

Cross sectionsof typical electrochromic windows (ECWs) have three tofive-layers of coatings that include one to thre

Examples of the cross-sectional ar-rangements can be found2in “Evaluation Criteria and TestMethods for ElectrochromicWindows.” (For a list of acronymsused in this Standard, see Appendix X1, Section X1.1).1.
5、2 The test method is applicable only for layered (one ormore active coatings between the TCEs) absorptive ECCs onvision glass (superstrate and substrate) areas planned for use inIGUs for buildings, such as glass doors, windows, skylights,and exterior wall systems. The layers used for electrochromi-c

7、n and reflectionand thus, limit the solar heat gain and amount of solar radiationthat is transmitted into the building.1.4 The test method is not applicable to other types ofcoatings on vision glass with other chromogenic coatings thatcannot be held in a static colored or bleached state.1.5 The test
8、 method is not applicable to IGUs that will beconstructed from superstrate or substrate materials other thanglass.1.6 The test method is not applicable for measuring theuniformity of ECC coatings during the coloring or bleachingprocesses.1.7 The test method referenced herein is a laboratory testcond
9、ucted under specified conditions. This test method isintended for use in assessing the changes in uniformity of anECC on vision glass, which will be incorporated into an IGUand subjected to a series of tests for assessing the durability ofthe coating or the IGU unit, or both.1.8 The values stated in
10、 metric (SI) units are to be regardedas the standard.1.9 There is no comparable International Standards Organi-zation Standard.1.10 This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish
