该欧洲标准定义了一种测试方法，以建立玻璃上的涂层的自洁性能，其利用太阳，雨水或太阳和雨水的组合来增强玻璃的清洁度。 欧洲标准适用于EN 1096 1和EN 1096 2中定义的A类涂层玻璃，用于室外建筑应用。该测试旨在适用于使用亲水或光催化活性官能团的玻璃上的涂层，以增强玻璃的清洁度。 测试程序没有具体说明涂层自洁功能的耐久性

This European 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 European Standard applies to class A coated glass as defined in EN 1096 1 and EN 1096 2 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.
