This document specifies requirements and corresponding test methods for nanoscale titanium dioxide (TiO2) in either powder or suspension form for photocatalytic application. This document is applicable to modified nanoscale titanium dioxide for photocatalytic application. NOTE Such modification can be surface treatment, coating, doping and combination thereof.
Abstract
Overview
EN ISO 18473-4:2023 (ISO 18473-4:2022) defines requirements and test methods for nanoscale titanium dioxide (TiO2) supplied as powder or suspension for photocatalytic applications. It covers modified nano‑TiO2 (surface treatment, coating, doping or combinations) and establishes classification, designation, sampling, marking and test reporting requirements relevant to manufacturers, suppliers and users of photocatalytic functional pigments.
Key topics and technical requirements
- Scope and forms: Applies to nanoscale TiO2 in powder or suspension form for photocatalytic use; modifications (coatings, doping, surface treatment) are included.
- Classification: Crystal structure is classified as anatase or mainly anatase with low rutile content.
- Designation: Materials can be designated by median primary particle size (d50) and other agreed characteristics.
- Essential requirements (summary of Table 1):
- Median primary particle size (d50): ≤ 100 nm (reported by TEM; D10, D50, D90 number‑based distribution and TEM image).
- Specific surface area: ≥ 35 m2/g (BET method, ISO 9277).
