Overview

This standard defines a test method to establish the self-cleaning performances for coatings on glass which utilize sun, rain or a combination of sun and rain to enhance the cleanliness of the glass. The standard applies to coated glass for use in outdoor building applications. The test is designed to be applicable for coatings on glass which use hydrophilic or photocatalytic active functionalities to enhance the cleanliness of the glass. The test procedure does not specifically address the durability of the coating's self-cleaning functionality. The test method was developed to be performed on monolithic samples of the products. In the case of a double-coated product (that is, a glass that has a self-cleaning coating on one side and another coating on the other side), it would be necessary to obtain the corresponding glass with only the self-cleaning coating on one side (or to remove the coating on the back side by polishing, provided that the self-cleaning coating on the opposite side is not damaged in the process). If this is not possible, additional protection should be applied to the coating on the reverse side (for example, a protective film with electrostatic or low-adhesion charge or by installing double glazing). In the case of tinted glass and absorption layers (a self-cleaning coating or double coatings), radiation absorption may affect the opacity measurements. The test shall be performed with clear glass and extrapolation shall be performed for tinted glass and absorption coatings.
