What is ISO/TS 22107 about?
ISO/TS 22107 establishes a generally applicable (i.e., not application-specific) definition for dispersibility. ISO/TS 22107 identifies significant characteristics for evaluating dispersibility and lists examples of methods used to characterize dispersibility in various applications.
ISO/TS 22107 applies to processes that disperse powders into a liquid continuous phase while reducing the size of agglomerates or flocs down to the intended level, that homogenize an existing dispersed solid phase of a suspension or the mixture of two suspensions, or that exchange the original continuous phase in a suspension for another. Specific methods to disperse particles and to characterize the state of dispersion and/or homogeneity are only referenced, if necessary, for context.
ISO/TS 22107 is applicable to nano- and micro-sized particles across a range of product applications.
Who is ISO/TS 22107 for?
ISO/TS 22107 on the dispersibility of solid particles into liquids is beneficial for:
- Chemical engineers
- Organizations dealing with chemical technology
- Laboratories involved with applications/products that need to determine dispersibility
Why should you use ISO/TS 22107?
Dispersing particles is crucial for many end-use product properties such as colour, sensorial quality, polishing, film homogeneity, conductivity, therapeutic efficacy, opacity of paints and inks, as well as UV protection in cosmetics. Dispersions are evaluated over the life cycle of a product, beginning in the design stage, through production, and for the end product.
ISO/TS 22107 provides a generic definition of dispersibility based on literature sources and other consideration. Being independent of the end-application, this helps align perspective of all entities dealing with dispersibility of solid particles into a liquid, and manage functionality of the processes.
ISO/TS 22107 provides references of standards that discuss methods to characterize dispersibility. Therefore, the quality of the dispersed end-product, e.g. stability, tinting strength, gloss development, rheological behaviour, opacity/appearance can be assessed.
Overall, you will be able to maintain consistency in quality of end-products by complying with ISO/TS 22107 and the referenced documents while avoid misinterpretation and remove any ambiguity between entities dealing with chemical technologies
