This Standard deals with fine ceramics. This Standard specifies a test method for the determination of the self-cleaning performance of materials that contain a photocatalyst or have photocatalytic films on the surface, and which are usually made from semiconducting metal oxides such as titanium dioxide.
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.
This European standard specifies a test method for the evaluation of the photocatalytic self cleaning performance of materials showing photocatalytic activity, usually based on semiconducting metal oxides such as titanium dioxide, by the measure under solid/solid conditions of the de-colourisation ability of a test sample under illumination with ultraviolet light (UV-A), previously coloured by spreading on it a dye solution and dried This European standard is intended for use with opaque and rough surfaces of different kinds, such as construction materials in flat sheet, board or plate shape, that are the basic forms of materials for various applications. This European standard also applies to fabric, plastic or composites containing photocatalytic materials that are not soluble in acetone. This European standard does not apply to photocatalytic glass, granular materials (unless they are deposited in compact films or layers over flat solid surface) and flat non porous materials. The method evaluates only the self cleaning ability of the material under ultraviolet light irradiation. It cannot be applicable to evaluate other performance attributes of photocatalytic materials, i.e., decomposition of water contaminants in liquid or gas phases contacting the material, and antifogging and antibacterial actions.
This part of this European Standard describes the methodologies to be used in a laboratory air tight chamber to test prototype or commercial air cleaner systems with a maximum flow rate of 1,000 m3/h used for the indoor air remediation. It applies to the treatment of atmospheres that are representative of the air inside buildings and workplaces. This protocol applies solely to photocatalytic systems alone or to combined systems that include a photocatalytic function. This photocatalytic function is demonstrated by verifying the mineralisation of model VOCs to form CO2.
