ISO/TC 256/WG 7 - Functional pigments and extenders

This document specifies sample preparation methods to determine the size distribution of separate particles of a single pigment or extender, which is dispersed in a liquid by application of a standardized dispersion procedure, using an ultrasonic device, shaker device or wet jet mill. The sample preparation methods described are optimized for measurements carried out with a particle sizing technique based on sedimentation. This technique relies on particle migration due to gravitation or centrifugal forces and requires a density contrast between the particles and the liquid phase.

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.

ISO 18473-3:2018 specifies requirements and corresponding methods of test for fumed silica in powder form for silicone rubber application. This document is applicable to untreated and surface treated fumed silica.

ISO 18473-1:2015 specifies requirements and corresponding methods of test for surface treated nanoscale calcium carbonate in powder form for sealant application.

ISO 18473-2:2015 specifies requirements and corresponding methods of test for nanoscale titanium dioxide in powder form for sunscreen application. This part of ISO 18473 covers the surface modified, TiO2.

ISO 10601:2007 specifies the requirements and corresponding test methods for manufactured and natural micaceous iron oxide (MIO) pigments, in dry form, used primarily in protective coatings for steelwork.

Specifies the requirements and corresponding test methods for manufactured and natural MIO pigments, in dry form, used primarily in protective coatings for steelwork. In accordance with current practice, the general requirements have been sub-divided to give those that are essential and those that are conditional upon prior agreement between the interested parties.
