What is ISO 22551 about?
ISO 22551 establishes a test method for determining the antibacterial activity of indoor-light-active photocatalytic ceramics and other materials, produced by either coating or mixing of a light-active photocatalyst in a simulated indoor lighting environment. The testing method is used to obtain the antibacterial activity of indoor-light-active photocatalytic materials under indoor lighting condition by contact of a test piece with bacteria suspended in a dispersion medium simulating human sebum.
ISO 22551 is intended for use with different kinds of indoor-light-active photocatalytic materials used in construction, for example, flat sheets, board or plate shapes, which are the basic forms of materials for various applications.
ISO 22551 is applicable to indoor-light-active photocatalytic materials produced for antibacterial application. Other types of indoor-light-active photocatalytic materials applications, i.e., decomposition of water contaminants, self-cleaning, antifogging, and air purification, are non-applicable by this method.
NOTE-
ISO 22551 is not applicable to powder, granular, or porous indoor-light-active photocatalytic materials, as well as cloths or textiles.
Who is ISO 22551 for?
ISO 22551 on fine ceramics is useful for:
- Fine ceramics manufacturers
- Ceramic injection moulding industry
- Dental product manufacturers
- Chemical engineers
- Testing laboratories
- Biomedical applications
Why should you use ISO 22551?
Test method specified in ISO 22551 helps to evaluate the suppression of contact infection of bacteria using an indoor-light-active photocatalytic material under indoor lighting environment. This method is applicable to materials with smooth surfaces, such as flat sheet, board or plate-shaped materials. With the help of this standard, manufacturers can ensure good quality of the fine ceramic.
The accuracy of the ISO 22551 test results will help in improving product development and quality control of end-products and thereby build trust of your customers. The results of these tests will equip you with making an improved decisions regarding the right chemical composition required in fine ceramics as the specific engineering and industrial needs.
